I was hesitant to utilize Quest Diagnostics for lab work due to all the poor reviews. The receptionist was a tad short in tone, but she was efficient and helpful. The phlebotomist (Mariana? Italian lady) was absolutely a charming delight. She drew blood painlessly and quickly, and she was engaging and so sweet. I did have an appointment, and they honored me before those that were there before me. I appreciate that since I did make the appointment and have to return to work. I was in and out in fifteen minutes. read more

I was sent here from Muir Health from across the street. There were two lab orders. Upon arriving I gave both lab orders to the receptionist at the front desk. I gave her my new and current insurance card. They pulled up my old health insurance plan in their computer which was gone for two months. I told them to process the claim under the new insurance plan because that one was the one that was the most current. The technician draws blood and there was a large hematoma at the injection site for several days afterwards. The size was over 3 inches. Then I get the results from the two lab orders. One was never performed because they dropped the vial of blood and it broke on the floor. The insurance company sent me an explanation of benefits for the claim submitted to them for my service here from 3/25/26. The claim was processed by this office using my old insurance which i clearly told them was no longer being used or paid for because my employer put me on a new plan with better benefits. I told them to process the claim using my new insurance. They did not listen and used the incorrect information from my old plan. The health plan should not be paying for a claim this way. This was my first and last time I go here for any blood work. If they send you here from across the street from the hospital or urgent care go somewhere else. read more

I debated about leaving this review as I understand that businesses, even those in the healthcare industry, are struggling at the moment. I made an appointment online a week prior. The sign on the wall said this location was "appointment only". I waited for 30min. Okay fine, things happen, I get it. What truly frustrated me was this: the receptionist asked me to confirm my FULL name, address, birthdate and THE SPECIFIC TEST I was taking in front of everyone in the waiting room. Actually, she just read it ALOUD from the computer. This is extremely inappropriate: 1) violation of my privacy; 2) did you train your employees on HIPAA?; 3) where is my right to consent? Are there really no better ways to confirm a patient's identity and purpose of visit? I chose Quest for convenience and this location for proximity, however I will NOT revisit. Absolutely horrendous customer service, punctuality and professionalism. read more

I've come to Quest Diagnostics a few times now, and for the most part, I have generally had a good experience. At certain times, one of the receptionists has gotten a little snooty. Other than that, the staff is really great; especially the phlebotomists. It's best to schedule an appointment if you can because this place can get PACKED, especially during peak hours which is around lunch time. I've waited for an hour and a half one time because I walked in without an appointment. If you make and appointment, you will save so much time and hassle, trust me!There's lots of seating available, but they can get full when it gets super busy. You can check in using the computer screen at the front desk and they will call you up if they need any additional information. The rooms and restrooms are kept really clean. The phlebotomists that I've worked with have always been very professional and courteous. They are quick and they make you feel very comfortable even if you are afraid of needles. It's a great place to get your lab work done. read more

See all

Not only they don't answer their phone. It's near impossible make an appointment. They say walk-ins available. Nobody helps you. The self check in system does not work. Nobody is there to help you, they don't open the door. They close before the hour is posted. read more

Sindy was my phlebotomist and she was amazing. She actually had to take 14 vials of blood and I barely felt it. Usually phlebotomists can have a hard time holding the needle steady for such a long draw, but Sindy was so steady and gentle. No bruise or marks left over. She was also very friendly and explained things to me thoroughly. I had a lot of questions about the billing and the different tests being done (since there were so many), and she was very patient and helpful. The woman who was working at the front desk was also very helpful and friendly. Unfortunately, I didn't get her name, but she was there around 1045-1130am on 11/20/20, so hopefully management knows who she is! She was also very patient and helpful and my situation was a bit weird with all my tests and she made sure everything was done correctly. The lab is very clean and quiet, no real complaints about the experience otherwise! read more

I've been here several times, but this is my first review. I will start out by saying the staff here have always been very nice. Unfortunately, every time I go, I get in late. Every time. If you get in on time, you're lucky! Why make an appointment at all if you cannot get in at the correct time? I didn't get in this time over 10 minutes past my appointment time. They removed my name from the list of people waiting before I was actually taken back to get the blood draw. My blood draw required 14 hours of fasting. Nobody asked me about fasting or confirmed that I had fasted for the correct number of hours before actually performing the blood draw. This is super important, because if someone was supposed to fast and didn't do it and they took the samples anyway, the results would be incorrect!!!! Tabitha was the one who drew my blood today. First time I've seen her there. I have donated blood NUMEROUS times and had blood draws performed, and her needle placement was the worst. It was not only uncomfortable but it HURT. She said nobody ever told her that before. Right. She also complained that their office had been understaffed for several days. read more

3 stars. I tried the day before my test to find out if I had to fast and their phone system directed me to leave a message and someone would return my call. That didn't happen. My dr office is impossible to get through to so I ended up fasting "just in case. " I get there for my appointment which having saved me no time btw. Everyone in the waiting room was still seen before me and my appointment was started late so....not going to waste time doing that again. But when I DID get back my associate was wonderful. Kind and efficient she found a vein with no problem and I was done and on my way lickity split. So...three stars. read more

I just want to say a Big "Thank You" to Jordynn the receptionist at Lab Quest . I went in to get lab work because my HMO decided I didn't need lab work ordered by an outside Doc...Jordynn so so professional and so friendly and made me feel at home! I was already nervous because of the lab draw I had to have! Arian the lab tech was Wonderful! So friendly.and reassuring. I actually felt in good hands! Arian was Professional,Knowledgeable, Confident. As a retired nurse just watching Arian do the blood draw I new she new what she was doing!Painless! Thank You so much ladies for making my experience The Best!! read more

No they change the system everything you have to do to check in what should I don't have a problem with it and they make it to one machine and people behind you in the line some old folks they don't understand how to open as information in and the lady sitting behind a countdown very rude but she don't have a breakfast in the morning and unbelievable that will be my last visit to this place I will go to John Mayer hospital much nicer much better place and very good access to your health so I request from everybody this place is the worst specially the lady work in the back in the register read more

Waits never more than 10 minutes. Waiting room very clean. Good pandemic spacing, and personnel friendly and professional.

They are apparently permanently closing the Concord location as of 9/9/22. There is no indication of an alternative Concord location opening. If that is true, then the closest location will be on La Casa Via in Walnut Creek - a long drive in rush hour traffic first thing in the morning. Sigh. read more

Stay away, stay away! I've got a fixed list of basic exams I needed done to apply for a certain position. Quoted in a couple of close by labs and this one came up a little cheaper. Came to the lab, paid, got the exams done and left. To my surprise two months later I receive an additional charge at home. I thought it was a mistake and ignored. Two weeks later I receive an agressive call from their precolection department saying my doctor requested aditional axams and I have to pay otherwise they would push me to collection and blablabla. Wait what? My doctor didn't requested anything, I came up with this list of exams myself, my doctor did not request anything. Person kept screaming at me and saying I need to talk to my doctor, no matter how many times I said this list of exams are for an application, doctor did not request anything. Please be aware if you care for your money. read more

I arrived at 9:15 am and was told it would be a 35 minute wait. One hour later I'm still waiting to be seen. The staff appears to be on the older side so maybe they have a hard time managing their time and are unable to handle too many tasks at a time. read more

I've had a great experience every time I've come here. I have a needle phobia and my veins roll which makes blood draw difficult. I've had two separate phlebotomists draw on me 3 different times and they were both understanding and helpful. I would definitely recommend this place. read more

35 minute wait after my appointment time of 810 and arriving prior to 8 am. Was texted at 815 they were ready for us and then not called back until 845. How are you running 35 minutes behind after being open for 40 minutes?! The worst part- I would not recommend coming here for your child as they are not all skilled enough to draw blood they don't know how to find the vein without multiple attempts and people. read more

I'm still dealing with long-neglected health issues after ignoring myself for years. Last Saturday, it was bloodwork. I've been putting off this bloodwork for about two months, the whole 12 hour fasting thing is tough for me. This Quest has Saturday hours, which is nice (8a-12p.) There were only 2 people there ahead of me, and yet somehow I got called in before them. Cool, bc I'm really hungry at this point, and want to be done and off for breakfast. Needles don't bother me, I've had a ton of bloodwork done in my lifetime, I don't mind seeing that vital fluid flowing into the vials. But for those of you who aren't fans, the Phlebotomist here is well-versed in small talk to keep your mind off of it. The waiting room was dark, there were lights above the reception desk, but nowhere else. Good variety of magazines. read more

I came to this lab at 9:30am and its 11:24am now and I'm still waiting. 2hr wait is unacceptable! They need to get more staff. Every time you come you need to show them your insurance card. I'm a regular here and you would think with today's computers they would have a database of people like many other doctors and labs do :-( This is not very efficient nor convenient for the customer. I had my blood drawn in this lab about 6x and each time it went well so I have no complaints about the nurses and their work. I would give them 5-star if the wait was under 20 min like everywhere else but over 2 hrs - come on people!!! I tried to make appointment but the lady at the front desk gave me a sticky note and told me to call 877 number. I asked her if I can just make an appointment right there and she said no :-( I went to run an errand and tried calling the location numerous times. They never answered the phone. Now I'm finally inside. It took 2 hrs and 15 min. It's also very cold inside :( read more

First tip - you must have your insurance card. Each time you visit they need to photocopy your ins card & attach it to your paperwork. This will seem aggravating, but now that you know why they ask you each time, it won't be irksome. The Process Once you step inside, go to the desk. It's a small space. You can't miss it. Don't expect to be greeted with a happy smile. Depending on the clerk, you might be ignored. Sign in on the sheet that's on a clipboard. It'll be there. After awhile they'll call you up to ask for your paperwork. If your doctor faxed paperwork over, tell them and they'll look for it. Sometimes they will ask your doctor name even though you'll be thinking "isn't it on the fax from the dr's office!?" You'll have to fill out your address & sign your name on the paperwork. If your paperwork isn't there, they can call your doctor to request it. They keep the paperwork you just signed. They don't talk very much so they may not tell you to go ahead and have a seat until you're called again, but that's what you need to do. They probably want to avoid saying the same thing for 8 hours/day. Also, some of the patients are seen regularly and know the drill, so explanations aren't needed. After sitting back down, wait to be called. Once called, they'll tell you to take the 1st or 2nd chair. Go thru the sliding door and slide it gently behind you. You'll see the 1st chair right away, the 2nd chair is anin the adjacent room. Have a seat. If you have shy veins like me, feel free to wind your arm around like a nut job, hoping to coax the veins to the forefront and ensure a smooth, pain free process. It usually goes pain free, but not always. On one occasions one of the phlebotomists jabbed the hell out of me and I was left with bruises, but I don't see her drawing anymore. Pros Walk-ins are ok Can book appts online, 24 hours/day Convenient location Easy parking Usually quick service - avg wait time start-finish is 15 min when I've walked in Cons None really. Just remember your insurance card! I didn't make an appt the most recent time. Caught the office during a rare rush & was there for 45 min. Etiquette - Not posted in the office but try to heed -- No loud talking. Of course once in awhile there is someone whose voice carries, but generally it's a quiet space. No talking on cell phones. Cell phone ringer off or on vibrate. Oh -- I was there the other day and saw people being asked to put their items in a lock box. I watched a couple of these scenarios and realized Quest does urine testing as well. Perhaps for employment and/or court purposes. If this is you, you will be asked to place valuables from your purse into a lock box. You'll have to hang your empty or mostly empty purse on a hook outside of the bathroom. Men just put their wallet & keys in the box. No manbags the day I was there. The clerk watches you remove everything, asks if there is anything in your pockets, then asks you to wash your hands. You go into the bathroom while they wait outside. After you're finished, they unlock the box for you and you get your items out. If I had to come here for this, I'd leave my purse in the car. Hidden, of course. There's can be some anxiety or worry involved w/blood draws. I think they do a good job of being efficient. I've never had any snafus or lost info. I've had at least 6 draws here, maybe more. I have a choice to go closer to my home, but have continued to drive over here. read more

Well, let me begin by saying that the receptionist is not rude, she is under a lot of stress with a terrible system for lining up patients that needs to be fixed IMMEDIATELY! She was very nice, even when being yelled at by very rude people who were extremely upset at their wait times, I actually felt sorry for her. ADVICE TO RECEPTIONIST: To make your life easier, you should tell people who do not have appointments, when they come in, that the wait time could be up to 2 1/2-3 hours, give them the option to make an appointment and come back, PLEASE. I was told it would be "probably about an hour" wait. I went in without an appointment around 9am, the place was packed. There were people there with appointments and people without. Every time a person with an appointment would come in, the people without appointments were pushed back. This is a TERRIBLE system!!! Even people WITH appointments were waiting for anywhere from 30 minutes to an hour. I did not get out of there until 12pm. (3 HOURS). I am sure the staff know what hours/days are the busiest for them, they should make those hours/days by appointment ONLY and allow walk-ins only during their non-peak hours... just a suggestion, but something that should seriously be considered. The week before, I went in at 2pm and it there was only one person waiting, I didn't have the proper paperwork so I had to come back (wish I would have made an appointment). BUT.. my point in mentioning that is - if you are going to walk-in, 2 pm seemed the right time to do so and not have much of a wait. I will not go back there without an appointment, that's for sure. If you decide to try your luck with this place and you have read this review, understand that you've been warned and do not get all pissy with the receptionist, who really is just working with an extremely unorganized and under-staffed company... it's not her fault. (though, she should be up front about possible wait times... still not a reason to get belligerent and rude with her... I HATE people like that.. asses the situation before opening your pie-hole and spewing out ugliness to someone who is just doing their job.). Take a good book or maybe bring the Lord of the Rings Trilogy to watch while you wait. ;) read more

Convenient location and time (open Saturday, and it's nice they have walk in appointments. The people were friendly and I didn't wait more than an hour. However, I have some serious bruising from having my blood drawn. It hurt when it happened and continued to hurt afterwards. When I took the bandage off there was a decent amount of blood (not the small dot I'm used to seeing). read more

So my experience today was quick and easy. I was worried since the majority of the reviews seem to be pretty bad. I made an appointment for 2:45 pm and was seen a couple minutes after that. The check in process is simple. They have two IPads there you use to check in. Have your appointment confirmation number ready to type in. If you don't have that you can use your name and phone number. I don't know what you do if you don't have an appointment. Then you just sit down and wait for your name to be called. The blood draw itself was quick and painless. She did something that I really appreciated. She put the labels on my 7 or so vials in front of me then had me confirm that my name was on those vials. That made me feel better that my blood would not be confused with anyone else's. read more

So I dropped in first thing on a Monday morning, and I had to wait almost 90 minutes. That was a bummer. In getting blood drawn, my vein can be difficult to find. My person (I wish that I had gotten her name) got it quickly and on the first try. She's a pro. I'm very happy with that experience, and to me that is most important. Sure, the place could use more staff. But one can make an appointment. I'll remember that if I have to come back. The woman at the front desk was busy, but friendly and courteous. I'm hoping people frustrated with the wait at this place don't take it out on the receptionist. The staffing issue there isn't her fault! read more

They treat it very badly and ignore it instead of answering the questions. They are alone and instead of giving good service for being 10 minutes late, give me two hours later and he says we are busy. It was a few minutes late, I had a problem with the lock on the iPad, and without answering, he was just mentioned to the iPad. read more

I followed Jackie A's advice and made an appointment online (quick & simple). Walked in at 8:30AM. Lots of parking available in the lot behind the building at that time. There were 8 other people in the waiting area when I arrived. Signed in, sat down, grabbed a magazine. They called my name within 10 minutes. Well, I should say Jessica, my phlebotomist, called my name within 10 minutes. I added one star to my review here because of Jessica. She was very pleasant, professional, well-organized and efficient.... Jessica was the bright spot in my morning today! I was out the door in 30 - 35 minutes... and had a smile on my face. read more

Disgusting wait times. Absolutely terrible. Everyone is the waiting room has been making jokes about the poor customer service. EVERY SINGLE CUSTOMER is upset - maybe that will inspire you guys to consider changing your scheduling methods... Only gave a star because I had to - they really don't deserve any. EDIT: And it's absolutely FREEZING in the office. It you do end up having to come here, bring a jacket! You won't regret it. read more

I've been in different labs in my lifetime. All use the method of first come first serve, especially when people are fasting. This is the only place that doesn't. If you dont have an appointment, you are screwed. You will die fasting in the waiting room because you are waiting for hours. UPDATE: THEY HAVE TWO COMPUTERS TO SIGN IN BUT IT SEEMS ONE IS SPECIAL ONE BECAUSE IT DOESNT PUT YOU IN THE LIST. read more

Absolutely the WORST! Staff are slow, extremely disorganized, super LONG wait. It's not brain surgery! I'd recommend going to another location. Concord Quest Lab location SUCKS! Id give "-0" stars if I could. read more

Rough start for this one. Site says one appointment available. I try to take it but it's for 2 hours earlier than the current time. It says walk-ins available. I hate being a walk-in because it's often a long wait. I'm fasting plus other test-specific requirements that are making me super uncomfortable. I go in anyway. It's close to home. I can't sign in, system in the waiting area says not taking appointments anymore but for urgent need, press "blue [help] button". That button leads to me getting a number to wait. I wait. One tech comes out a minute later to tell us in the waiting area that if you haven't checked in on their system, they're not taking any more patients. Good thing I checked in and I'm holding spot "#6". She disappears to the back. I wait 20 more minutes as those with appointments go ahead. Waiting room becomes increasingly busy. Another woman checks in as a walk-in. #7. Another lab tech emerges and says anyone that didn't have a prior appointment cannot be seen today. I argue that I've been waiting 20 minutes since the last tech said if we'd checked in already we were good. She clarifies, "No, only checked in with appointment. Not checked in as a walk-in." Ugh...I tell her I could have made it to another location before close had the previous tech been more clear. Also add that I'm fasting and desperately need to pee (which, of course needs to be saved for the test). She says to wait. I wait another 20 minutes. Original tech comes out and says it's now noon and they are closed. No time for me. At this point, I'm hungry, thirsty, off pain meds and supplements for 4 days, and desperately need to pee. I tell her I'm frustrated about the miscommunication and that I could have gone somewhere else had it been more clear in the beginning. She is clearly also stressed and frustrated but understands and says they'll take care of me. I ask for the other tech (just because she seemed less stressed). I'm an easy draw and she was quick. I thanked her for taking care of me and we both apologized for the hectic situation. Glad they made it work after all. read more

Today is the first time of my visit in this location. I really have a very bad experience with the nurse who is on duty.

After almost 1 hour of waiting behind no one else I had to get up and leave this unprofessionally run lab. Overhearing the employees make personal phone calls both on office and cell phones, lewd conversation and losing patients urine samples I could not stand this place any longer. I tried to contact Customer Service and Human Resources which was about as fruitful as the hour long wait itself. Go anywhere but here. This is an incredibly unprofessional place to have any work done let alone lab work. Ridiculously Shameful. Good thing I did not need a band aid. read more

thankfully, when i came in around 3:30 pm the other day, there was no wait, but i didn't have anything to drink all day and was very very thirsty so i asked for a small cup of water... i came in for a drug test for my work.. they were so stingy with the water.. i didn't even get any! when the lady asked me if i still wanted the water before i went in, another lady who took me back said there was no time and i had to go back ASAP... wtf.. oh yea, there was one guy who came in after me and he's a regular... seriously. ITS WATER U IDIOTS. read more

I don't know about other quest locations, but this one sucks. You set an appointment, only to wait in the waiting room for over an hour....and this is every visit. The phlebotomists are not super professional. I've had bumps and bruises the last 3 times I came here from where they drew blood at. They also don't seem to care at all about the wait time. Like we are all just here for a good time or something? Two thumbs all the way down! read more

I was expecting the worst, based on these reviews, but was pleasantly surprised my visit went off without a hitch and everyone was very friendly. I needed a special test done and figured out online that Quest offers it. So I made my appt online the day before. Since they close kind of early I decided to drop off my doctor's order in their mail slot on the way home. When I arrived the next morning, everything was all set to go. I was in and out of there in 15 minutes. The phlebotomist even did a good job with the draw, and I've had trouble with my veins not cooperating lately. Overall pleasant experience! (As long as nothing goes wrong with the insurance!) read more

Waiting times are still absurd, I got a laugh when I saw reviews from years ago mentioning the same issue. I unfortunately had to cone here for a employment pre screening but if you have the option avoid then for a better option. read more

Receptionist is very rude! Wait hour is horrible! I made an appointment for 9:15, and the system didn't show my name. The receptionist still refused to treat me as a person with appointment. When I asked how long I should wait (came here empty stomach), she looked unhappy, and literally said "you're the last one". Very bad service and attitude. Not coming here again! read more

I would suggest in going to a different Quest. I've been to a few Quest and the lady yells your information aloud to the waiting room. Your doctor name, address, and test being down. So, I overheard a lot of patients private information. She required that I check in on the tablet even after checking in on my phone like I have with every other Quest and when I started to check in she started clicking back on questions I already answered and then started pressing the buttons herself. I chose to wait outside until they were ready for me (like I do with every other quest) and they called me in 20 minutes before they were actually ready for me. Every other location I have been to is structured and ready to take on the patients in an orderly fashion while not having them wait any more that 5 minutes unless they need to verify information or change a code for your lab request. Less professional and less structured then other locations. read more

MAKE AN APPOINTMENT!! With a appointment I waited for 20 minutes to get some blood work done. Others in the lobby were starting to riot because they had been walk ins, and had been waiting as long as a hour and a half. Its not that hard to call ahead and get it scheduled and I am glad I did. The office is brand new, they moved across the hallway. Much more seating now and very clean equipment. Only complaint is that the chick that drew my blood literally shoved the needle into my arm at warp speed. OW! read more

Terrible service, receptionist is extremely rude. After my doctor sent me here for lab, I was led to believe I had an appointment. But after waiting for almost 2 hours, she come and asks me if I'd like to come at another time. Terrible clinic, extremely bad service. Tell your doctor to recommend some place else. read more
