THE worst Quest Lab in the San Gabriel Valley. They simply can't keep appointment times. The management of this lab is FUBAR. Waiting room is packed. Choose this Quest and you will also choose to waste your day waiting. Maybe an hour plus. LabCorp runs a better operation overall for your labs. Street Parking is also terrible or you have to pay. I changed this from 1 star to 3 because my particular phlebotomist was friendly and professional but losing an hour of my day when it should've just been 20 minutes sucks. read more

Came here to say that the street parking is still super limited. The clinic itself is running behind as others have said (today is Wed 9/23/2026). read more

This location is horrible. The staff are rude. No people skill what so ever. A person is here to drop off test for his elder mother, but they will not take it because the lady (staff) said they we will not take it. She also said they can't take walk ins because the system does not allow them. Not even when people are in urgent of getting the results. You can not make an appointment when it's urgent. Quest Diagnostics is discriminating against these people. I need to get a test done for a Monday appointment and today is already Friday. Ridiculous What I do not understand is why Quest Diagnostics is continuing this kind of atmosphere where there are tones of complaints about they way they work. read more

This Quest is in the same building as my doctor's office and near my house, so it's my preferred location when I need to have blood tests done. They are even open on Saturdays, which is convenient. There used to be someone that worked at the front desk and would check you in but that is no longer the case. Instead, you check in at one of the kiosks. I also recommend making an appointment in advance as walk-in appointments are hard to get and the wait will be long. The Phlebotomist that drew my blood on my recent visit was a darling lady named Martha. She was so friendly. Saying "Hi" to everyone and engaging me with fun conversation to keep my mind off having my blood drawn, which I hate. If it were possible to request her each time I would. I was surprised that my results were ready the next day and like that I can review them online. read more

Quest Diagnostics - Laboratory Testing Near Me - Pasadena, California

Fully aware this may be a bigger company wide fix, but just putting it out there: if you're not contracted with someone's insurance, there should be a way to let them know BEFORE they get called back. I walked in, with my lab order, used the kiosk to check in, and it had me scan my insurance card and ID. That would have been the perfect time to alert me that hey, we can't take you because we don't accept your insurance. Or you could've also said "this is how much it'll cost out of pocket, would you like to proceed?" But no, you just wasted my time. So there I sat, full bladder, fasting, ready for lab work only to be told not only could I NOT pay out of pocket (weird) but that i pretty much wasted a morning read more

If zero stars were an option that's what I would leave. The check in setup is ridiculous, no human interaction no human available at a front desk to ask about estimated wait times. There are TVs however they do not display the wait queue, useless.There are people with appointments that are waiting past 1.5hrs after their appointment time, walk ins are much longer wait times. The staff I'm sure is busy, over worked and under paid it reflects on their attitude towards the patients that are waiting. When they are approached to get any information or estimated wait times they are rude,short and dismissive. Everything here needs to be improved. Get it together quest! Staff does not care/lacks empathy. read more

Had such a great first experience at this Quest Diagnostics. I had an appointment and was seen right away, which made everything so easy. The phlebotomist, Elizabeth R., truly went above and beyond to make me feel comfortable and at ease. I'm usually pretty nervous with blood draws and fainting spells, and she was incredibly kind, patient, and reassuring throughout the entire process. I really appreciated how well taken care of I felt. read more

I am a cancer patient, and this was by far the worst experience I've ever had at Quest. I waited for almost an hour, and unfortunately, the nurse did not seem to know what she was doing. I experienced a tremendous amount of pain during the blood draw. It was an extremely painful and upsetting experience, especially given my medical condition. read more

Didn't realize this location was so close to me either while I was in Pasadena. Turns out they have several locations which make it easy. Appointments are recommended. Some locations open on Saturdays, which I appreciated. Call first to be sure their location is open. I originally called Arcadia but they are currently closed. Martha who took my labwork was sweet. She was professional and welcoming. They are an extremely busy location. Easy check in. read more

Made an appointment with a human and I show up and there's no appt and no human to even speak to here. Horrible ... read more

Avoid at all costs. My wife had an appointment, the waiting room was full, there were no free chairs, and she ended up waiting an hour and 15 minutes before she even got called in. It's completely disrespectful to patients. read more

Should not take 7 days for blood work to come back. They can't do their whole job. They get you the basic information within a day or 2 then crickets for over a week. Been since June 1 and I still haven't gotten the full results yet. This isn't the first time, it's every time. We gotta go back to calling idiots idiots again. read more

This place used to be the fastest I've have been, with or without appointments. Now they are slower than a turtle. I hope they get back to the fester way. read more

Quest Diagnostics - 4 hours for a walking and 1 hour with appointment. - Laboratory Testing Near Me - Pasadena, California

This is the most unprofessional experience. I set an up appointment to this location, brought my referral that they sent me in my email and the staff were so rude about it being on my phone. They made me go back in the waiting room until they received the email. The staff expressed how long it takes them to receive the email. I brought in another referral that I had in hand and all she did was enter information from it on her computer and hand it back to me but she could take the info from the form on my phone and type it in. This place is ridiculous and here I'm waiting........ the way that she handled it could have been way nicer. Go somewhere else read more

The staff is so kind here! Please make an appointment, or they will likely not be able to see you. They are understaffed and doing their best with how many patients need collections done. They are doing everything on their own and have no front desk staff to run everything and help out. Everything will go smoothly if you make an appointment. read more

I had a great experience at Quest today. Expected a long wait due to Saturday appointment but was called in within 5 minutes. Maria was very courteous and did an excellent job drawing my labs. read more

My child had a 7:10am appointment (booked weeks in advance), we were there on time, but the building was locked. Finally a man unlocked the door, but Quest was locked. When they finally unlocked the door, their internet was down. Nobody could check in or get a blood test. We were told to check in online, but I didn't have such option, maybe because I was checking in my child, a minor, not myself. I got in line at the iPad; by the time the Internet was back on and I checked in, we were more than 10 min after our appointment time and got rescheduled for 9:30. For medical reasons my daughter's blood test has to be very early in the AM; after 8am it's pointless. The nurse refused to work with us, blaming "the system". What about special situation, special measures? We did have an appointment, and we were there on time! The system didn't allow us to check in on time. She said that she didn't know if we were there on time or not, although I had spoken to her earlier when they unlocked the door about my daughter's situation. She didn't care about our 7:10am original appointment time, while the man with a 7:40am appointment was just leaving after his blood test. They didn't try to do anything to honor appointment times for several of us who had been waiting at the door since 6:30 or 7am. By 8am I am pretty sure they were seeing people with appointment times later than ours, that got there after us, and probably checked in after we did. How is this fair? The lab order was already in their system, along with insurance and credit card information. It would have taken 5 min to help my child. Now it's impossible to find an early AM appointment at any Quest lab in the area for the next several days, and my daughter's upcoming doctor appointment at CHLA is up in the air and very difficult to reschedule. Does Quest even care about all the problems, the inefficiency, and the very bad reviews at many locations in the area?? Today they simply weren't able to think outside the narrow lane named "the system, the system" and couldn't find any reasonable solution for the people with early appointments that had the bad luck to be there when the internet was down. read more

I had an 08:40 scheduled appointment. Arrived a bit early and the waiting room was full, no seating available. My only purpose was to drop something off. There is no wait room staff. Why did I have to wait an hour to hand your staffer my test? There was another patient who had been waiting since 07:30. They were very upset, and talking aloud complaining. There were patients having conversations on their phone. Go outside and complete your call. Have a staff in the lobby, who can be of assistance. Having to wait for over an hour for a scheduled appointment is absurd. Quest over books appointments. DO BETTER! read more

This is a review specifically for Maria, who was exceptional! It was the quickest, easiest, most painless blood draw. She is also kind and patient. Thank you, Maria! read more

I'm knocking off a star because of the limited free parking. It should be against the law to pay to park for any type of medical appointment! Parking* --Street parking is limited. There's a ton of parking lots around. It was easy to find at 730am. Free street parking after 6am except Sundays and I would suggest parking on Allesandro (the street after Bellafontaine) as the entrance to quest is on Allesandro. Location * -- There are two buildings for "50 Bellafontaine." Make sure you go to the North building. Quest is on the bottom floor by the fairmont pharmacy. Hard to miss. There are many Quests to get your labs drawn around the area. However, this is one of the only ones that open early at 7AM. Easy to make an appt online which I would suggest as it seems like the walk ins were waiting. Had Rachel as my phlebotomist and she was great. There was an issue trying to find my lab purchase but more on the fault of the other location I went to on N Madison.. she tried resolving by calling Veronica, the manager for the area and I'm impressed that she picked up bc it was obvious she wasn't working. I would pick this location PS: you can buy quest tests online but double check with ulta lab tests online (it may be cheaper$) read more

Quest Diagnostics - Waiting room - large - spaced out chairs with 3 check in machines - Laboratory Testing Near Me - Pasadena, California

See all

DO NOT use this branch of Quest! Their incompetence is beyond belief. They have lost my lab orders or samples more than once. Left me in the waiting room for hours after being checked in. And they frequently say they don't have me in their system despite showing them confirmation emails for my appointments. And all you will get is attitude from them - no apology, no empathy that this a is health care issue, nothing. They take no accountability for their completely shitty customer service and lack of concern for their patients. I have never had these issues with other Quest branches - just this one. Avoid at all costs! read more

This is one of the first times I am leaving a 5 star for this location! I had the pleasure of being cared for by Lucy, my phlebotomist this morning. Whatever momentary, slight discomfort there was from the needle was quickly forgotten because of her friendliness, gentleness, and truly caring manner. She put me completely at ease and treated me with kindness and respect. I sincerely wish all the techs here would follow her example - she is a reminder that skill paired with compassion makes all the difference. I also hope management recognizes Lucy for the excellent care she provides. I am deeply grateful for her professionalism and warm spirit. Thanks, Lucy! read more

Despite having an appointment I was seen an hour late. The waiting room was packed inside. The phlebotomist was extremely rude. She even told me that she wouldn't input my doctor's order for tests in her computer because it was written out manually and it would take her too long. Then she decided that something on my order wasn't properly written out, so she wouldn't test for that. She addressed me a few times to complain about the order each time. She drew blood, ordered me to sign some forms and I walked out as quickly as possible. I am never going back there. read more

Not sure why this location has such a low score. This is the primary Quest I go to and have never had an issue. I guess it's one of those things where ppl only leave reviews when they have awful experiences and don't think to leave a review for a chill, typical experience like I have for years. Everyone has been friendly and attentive. The location is always clean. In and out in usually less than 20 minutes (this time less than 8 - I timed it was curios lol). APPOINTMENTS ARE KEY!! I never go to any Quest without one. I've often always gotten one same day. Parking is tricky. I'd advise giving yourself a 5-10min buffer to find a spot. All in all it's been quick, easy and painless for me. I guess I'm blessed per all the other reviews?!‍ read more

Avoid this location at all costs. Staff is extremely slow with what they do. Average patient goes in and 15-20 minutes later they come out. Anytime I've gotten tests done anywhere else it's a maximum of like 5-10 minutes. Have no idea why they are so slow here. Only worth it if you have an appt and live close. read more

Worst ever location if you do NOT have an appointment. I just waited 1.5 hours to be told they are not taking walkins due to staffing. I get it. But let us know when we sign in??? Or put a sign on the door that says No Walk Ins today. No apologies or concerns from the staff. After another woman left highly upset, the staff could be heard laughing about it as she walked away. Horrible. Never coming back here again. read more

Terrible service from phlebotomist Lucy (Lisa). She's extremely rude and incompetent. She asked personal questions, didn't change her gloves and didn't even check my ID and insurance read more

This is not directed towards Quest as a whole, I generally have a good experience. However, this comment is about the staff at 50 Bellefontaine St Pasadena, CA..don't go to this one The staff was extremely unprofessional. Most people had appointments, but had to wait for over an hour to be seen. The patients were frustrated, rightfully so, however, the staff was extremely unprofessional for engaging in bickering with frustrated or confused patients rather than handling the situation professionally. And it was obvious they were backed up, but the phlebotomist was rushing to a point where I did not feel comfortable. In my opinion, this location needs to be evaluated for workflow and staff conduct read more

I had a great experience today with Quest. I went in without an appointment at 7:30 am expecting to wait an hour. I went and waited 2 min.!! I had the kindest phlebotomist, Maria. She was professional, kind, and attentive . It's a clean environment with plenty of seats in the lobby. Self-checkin kiosk for a quick check-in. read more

I'm honestly surprised by the negative reviews because my experience at this location has been great! The staff is super nice and helpful. This was my second visit, and just like the first time, everything went smoothly. They actually called me five minutes before my appointment to check in, which I really appreciated. The check-in process was easy, and the person assisting me was incredibly sweet. I was in and out quickly definitely one of the more efficient and pleasant lab experiences I've had. Also, parking has never been an issue for me. There's street parking available, and I've always been able to find a spot. But if you can't, there's also a parking structure nearby which is super convenient. read more

LUCY is the best!!! The sweetest lady, kind, helpful, patient!! I always go see her when I need to get blood drawn. She makes my day off to a good start. Thank you LUCY!!! read more

I am writing this negative review not because I think Quest Diagnostic does a poor job with blood work It's there scheduling that is NO GOOD !! I've been to this location 2 times in the past month and had to wait for a scheduled appointment 1 hour. Don't schedule an appointment if you're not able to service your customers!!!! read more

Needed to get a blood work up. Checkin was easy at the kiosks in the waiting area. Had an appointment and was taken in within five minutes of my scheduled time. Phlebotomist was friendly and efficient. Parking is an issue read more

I have been receiving the Service for a long time, as diabetic I go constantly there. The las visits I have been, I noticed that the offices have no more assistance in person, not even online nor by phone. I got cancelled an appointment one day before and I just receive a text saying to re-schedule. I got my appointment three months earlier, and now the closes one was three weeks after my Dr's appointment. I have PPO and so grateful that LabCorp staff was able to help me with this. Now I am going to LabCorp with people that really can help. read more

Waze takes you to a parking lot on Bellefontaine that faces a bunch of medical buildings. Zero Quest signs anywhere, building, parking lot - nothing! Put the address into google maps and it takes you to a dentists office. Finally I see someone coming out of a building and enter, still zero signs. Walk around the first floor and find a door, easily 300yards from the lot that says "Quest." Go inside and scan a barcode like a robot and it says you are 10min late, need to reschedule. Go fuck yourself Quest. read more

NO WALK-IN POLICY - 3-Hour Wait with No Resolution - Unacceptable Service I visited Quest Diagnostics as a walk-in and ended up waiting over three hours without being seen. No one provided updates, and the staff seemed overwhelmed and indifferent to the growing frustration in the waiting room. While I understand appointments take priority, holding walk-ins for hours without clear communication is unreasonable. If they can't accommodate walk-ins, they should say so upfront instead of leaving patients stranded. Other labs manage appointments and walk-ins efficiently--Quest needs to either hire more staff, improve scheduling, or stop accepting walk-ins altogether if they can't handle them. Wasted my entire morning, and I still didn't get my test done. Never again. read more

Went in for a routine blood draw w appointment and ended up waiting over 45min. The room was packed w angry people. Worse is the attitude of technician, when asked for the reason for the long delay even w the appointment, she callously responded "these days everyone has to wait, even when you goto doctor's office you'll have to wait". Her attitude was utterly despicable. Worse still, since she was the one holding the needle and stabbing you with it, you're made to feel more like a victim than a patient. Healthcare system in general is collapsing in the US.. technician's callous attitude is further proof of healthcare corp giants are now openly victimizing the public read more

Make. An. Appointment. It can be hours of waiting without one, even when there is hardly anyone in the waiting room! Vanessa is the best! All 2 stars are for her. No one else seems to know what they are doing, they're very unfriendly, terrible bedside manner. A woman yelled at my friend for taking a picture of her blood vials as part of documenting her health journey. There are no signs up or rules about photos, and the attitude about it was unnecessary, regardless. Vanessa takes the time to explain each process to you, she knew how to combine several orders so we didn't have to be sent to multiple labs to get the blood work needed. She was ok the ball, really efficient, very kind and friendly. There is always street parking available when we come, the building is clean, the waiting room is clean with lots of room to spread out. Unfortunately, they have to volume up pretty high on the TV which is constantly playing basically hold music and ads for Quest. Super annoying, especially when you have to wait so long. read more

Do these people realize that they are in health care? That means treating people with respect and courtesy. Today was the second visit my husband made to this location in the past five months, and both times he was treated like a number, not a person. Yes, his blood was drawn efficiently, but he was never greeted, smiled at, or thanked. Sure, people can have an off day, but I get the feeling this is the standard practice here. Get people in and out and don't waste time with niceties. News flash to staff: You're dealing with patients who are likely stressed about their health. The last thing they need is to be made to feel like they don't matter. read more

Wow. Let alone the long wait times, there is a reason there is a human entity during check ins- to help people. An elderly couple didnt know how to check in properly and they were so busy a person who worked there came out and essentially was yelling at them- i get they couldnt hear, but it was obviously from frustration as well. That they just gave up and left it to the other guests to get them checked in.....i nearly laughed because Quest diagnostics your guests dont work for you. Hire people, have a front desk check in. Its disgraceful. Me and another person had to thelp the guests get checked in. I have never seen this in my life before. Bad company. bad service. Don't go. read more
