Shoutout to AMARI, from the minute she called my 9 year old for a blood test, you could feel her positivity. She was so kind, gentle and explained the process step by step. Thank you AMARI for being awesome! read more

I had labs done at Quest, and while I was there, the phlebotomist told me they don't perform the bile acid synthesis test and that I needed to go to Labcorp. After finishing my other tests, I left, went back to my doctor for new paperwork, and scheduled another appointment at Labcorp--only to later see that Quest had already run the bile acid synthesis test and posted the results in my app. This kind of miscommunication is unacceptable and caused unnecessary stress, time, and extra appointments. read more

Wednesday, 3-03-2026: I conveniently scheduled my appointment on their app. So I checked in on the app and took a seat. I never wait long. This visit was with Al and she was downright professional but friendly. I have tiny veins and some techs have a hard time tracking mine down. She adroitly found one and was on target. I didn't feel a thing so that is skill! I complimented her, which was met with a smile. Lastly was the apple juice test and I was on my merry way. This place is great! read more

See all

I've used this location 3 times now at different times of day, and every visit involved a LONG wait (hour+), even with an appointment (which I always do). The waiting room is small, always standing room only and there are only kiosks to check in - there's never a receptionist manning the room. They'll tell you that they overbook and never have enough phlebotomists working. My attached pic shows every seat taken and to the right, a peek of standing people lining the wall - ugh. On the positive side: - there's lots of parking - this Quest is located in the Makena Medical Center Building, upstairs across from the Rancho Family Medical Group Office. - Chloe, my phlebotomist this last time, was amazing. I have extremely small veins and blood draws are usually very difficult and time-consuming. But Chloe was able to get a vein for 10 vials...with no bruising afterwards! And she was extremely personable, to boot. Although they'll tell you that appointments take priority, that's not what I observed with the many people coming and getting in. If they could properly staff, this could be a great facility. And if I could make an appointment directly with Chloe AND get in promptly, this would be 5-stars! read more

Quest Diagnostics - every seat taken and standing people lining the wall to the right! - Laboratory Testing Near Me - Temecula, California

How do I even start? I arrived at 6:55, about 5 minutes before they even opened so I could be the first in line for standby. I had to be fasting and there was absolutely no appointments available. Well, I was first in line but they kept calling the last people to check in for STANDBY, they did it 3 times!!! I asked what was going on and they said their computer was having issues, even though I let them know MY name was the first. I waited 2 hours, they kept calling later appointments that were checked in even though it was not even the time yet. The standby list was extra long and I just felt so frustrated that my only option was to leave. It is the second time I come to this location and staff doesn't even bother to do their job right. Unbelievable read more

Avoid this place. They are unorganized and super slow. Expect to wait at least 4 hours if you walk in.

I had a scheduled appointment for 11:00am. This was a fasting blood draw. Two people short, no room to sit, it became standing room only. The business should have called on temporary help to assist with the backlog! read more

This location is so understaffed. Save your time and book at another location this one is mismanaged.

Zero if I could. I refuse to go back. Horrible service and follow up. Still trying to get results from August 22. Doctor's office has tried also!! Ridiculous. Can NEVER talk to a live body. I have been patient but enough is enough!!!!!!!! read more

Jenn alone was my lifesaver. After a horrible experience at the other location she helped me through a pregnancy glucose test and made sure I was taken care of. So personal and wonderful read more

Zero stars. Can't speak with a receptionist to see if they have my doctor's order because they dont have a receptionist. Made an appointment for 1:20 and waited an hour then I walked out. There were still at least 6-8 people ahead of me still waiting. I would have told the receptionist I had to leave, but they dont have one. What a waste of time. read more

Went in today for lab work. Checked in via text. @ 5 mins later I was assisted by Jen. Very professional, friendly & fast! 0 pain! Not even a lil prick. I have had my share of labs drawn over the last.... Many moons and cannot remember one other time that I did not feel a needle going into my arm. Thank you Jen for exceptional patient service! read more

Checked in for an appointment for 11:30 and still had to wait an hour and a half before I was able to get my blood drawn with a room full of appointments past their time to be seen and only 4 on the standby list. Absolutely ridiculous! read more

Their appointment system is dumb! Our appointment time is at 8:40 am and came there exactly at 8:50 am and they wont accept our time and put us on standby list. My son is a minor and his lab draw is a fasting one. Talked to one of the person that works there and they are not even accommodating at all!!! Mind you all of the people checked in are way ahead of the their appointment time and they couldnt accommodate my son!! This is stupid! If you can give this place 0 stars i would've! There is no actual person to even talk to if there is something wrong! Do better and be at least accommodating!! read more

This facility is the definition of efficiency at the cost of humanity. If you are technologically impaired, need help checking in, or have questions of any type, you're out of luck. There is literally no one there to help you. The waiting area consists of a dozen or so chairs and two check-in tablets. By their "I don't care" attitude, it's plainly obvious to see that the phlebotomists working there are overworked, understaffed, and ignored by whoever runs the place. The management has pushed them to the point where they no longer see patients as people so much as veins to have needles inserted into and moved on as quickly as possible. If I had a choice to go somewhere else, I would happily allow whomever owns the Jefferson branch of Quest Diagnostics to go permanently out of business read more

They need to have personnel working the front desk in addition to the kiosks like LabCorp does. This office depends on two automated kiosks with no one to assist a room full of patients. Not even a bathroom code is displayed. Patients have to flag someone down just to ask simple questions regarding the kiosk, confirming their lab orders were sent in or where to merely drop off specimens. While I was waiting, a patient came in unable to read the kiosk and no one to help them. I had a mishap with the scanner unable able to read my digital insurance card through my phone. I thought the kiosk completed my check in when it beeped however, it deleted my info I had inputted when it didn't scan properly. I waited for an hour before I flagged someone down to check where I might be on the standby list. She informed me I was not on the list at all and proceeded to check me in properly. She placed me on the wait list without my insurance card. I then asked if I can be moved up on the standby list since there were many other standbys that went ahead of me already that got there after me. She said she would put a sign on the door to call me next. Didn't happen -I was there for 2.5 hours. I attempted to talk to a couple of techs in between to no avail. Further, I was not there to have labs drawn, I was there to drop off a urine sample. I'm hoping the specimen isn't spoiled by the time they got to me. I don't think it's unreasonable to ask to have someone working the front to ensure patients are properly taken care of. read more

Staff are always friendly and professional. With an appointment I'm in and out fast! I like that you can check in via the text they send you. read more

GO SOMEWHERE ELSE ANYWHERE ELSE. No receptionist so u can't ask a question - employees are like ghosts they quickly disappear behind door before you have a chance to ask a question. Terrible customer service!! read more

UPDATE!! Once I managed to figure out scheduling an appointment I had to update to 5 stars. They were very organized professional and helpful. Did I mention it was the easiest and painless blood draw I can remember. Thank You Quest team. read more

Mary was amazing and understood that my sister was a hard stick to give blood. She got it on her first try.

No one at front counter and the staff are rude. I will drive 30 minutes to go to another lab before I would even come back.

They should say it's appointment only. My child needed a test done between 7-9 am per the test requirements, there were no appointments during that window for weeks. I was told I could walk in. The computer says it should be about 30-60 minutes. They never saw us. We got in at 7:10 and waited until 9. There is no one you can talk to in person or over the phone just an automated answering machine and the people at quest do not help at all. Complete waste of time. read more

I waited for 2 hours, and when it was finally my turn, the appointment line was manipulated. I went from being next in line to suddenly being 3rd again. This is unfair and such a waste of my time. They have a display of names in the lobby and I wished I have taken a pictures of it. Our healthcare system has gone really bad, it didn't use to be this way. They also need a receptionist in the front. read more

If you don't have an appointment forget it. I did the walk in kiosk and it estimated 30-60 minutes When I came in I was #6 on the list. An hour and a half passed by and I asked what number we are on for the waitlist and they havnt even reached the first name on the list. I wish they would've told me this before I spent nearly 2 hours here. 2 hours and still not one person from stand by has been taken care of. The need to be accurate with these wait times because this is ridiculous and unprofessional read more

This location is inefficient and disorganized. No front desk help and their check in system doesn't update. This has been an issue here for years, it's hit and miss. I routinely wait 30 minutes or more when I have an appointment!!! Avoid this location! read more

I didn't have an appointment but was seen right away. I totally fainted and Chloe took such great care of me!!

Everyone working at Quest has ALWAYS been courteous and helpful, BUT... I'm a senior and I tend to struggle with today's technology. So I was not looking forward to messing with that check-in screen and the usual long wait AGAIN. This morning, however, I got a text on my phone from Quest stating to click on the text on arrival. I did so 1 minute before my appointment. Instantly I got a message stating that I was checked-in and to have a seat!!! About 5 minutes later my name was called by a pleasant tech telling me to follow him. Within about 10 painless minutes, I was heading out the door! THANK YOU Quest for this exceptional experience and service.!!! read more

0 stars if it was possible, I scheduled an appointment for 10:20, checked in right on the dot. Only a tablet to check in with, no human. It confirmed that I was checked in. I heard a woman in the waiting room say she had been waiting 3 hours... well I waited an hour and never saw my name populate onto the screen, thinking there was just a lot of people ahead of me in line. The person working and grabbing the next patient came out and was calling names and no one she called was there (assuming they also waited hours and probably left) anyways she grabbed a list and started go through it to see who was there and who wasn't, she called my name and I was about 8-10 people down so at least I was on a list. Waited another 30 minutes and still never saw my name on the screen so I went up and asked if we really were checked in for an APPOINTMENT and not a walk in and she said if our name isn't on the screen then we didn't check in right. Staff was extremely rude. I just left instead of waiting any longer like the other people there. Do not use the Quest office and schedule for them to come to your home if possible. read more

That only take appointments. If you walk in you will wait forever. They never answer their phone. I just needed to pick up a test kit to do at home and waited over an hour. read more

Every visit to Quest is a hassle and not a pleasant experience. Staff are rude and they don't seem to care about their patients. Whether it a bad attitude, delayed time regardless if you have an apt or not, missing referrals due to "their systems", it never fails. I wonder if bad reviews are even looked into and addressed? I've had to use quest for years because of my insurance and nothing has changed in a positive way, only negative. read more

Never fails. Every time I have to go to Quest something happens...either they can't find my order or (and this happens most of the time) They are waaayyyyy behind. My appointment was made weeks in advance for 10:30am. (And let me add I had to fast.) I'm still sitting in the waiting room 45 minutes after my appointment time! I am changing doctors solely because the only lab they work with is Quest. I'm not doing this anymore! Do yourself a favor...go two doors to Lab Corp. They are awesome! read more

I had an appointment for 8:40 in the morning. I checked in at 8:30. At 8:55 there were still two people ahead of me in the check-in line. This was basic bloodwork that should've taken no more than two minutes. I had to leave because I had a work call at 9 AM What's the point of making appointment if they can't honor the time. They should either hire other people. In the future, I'm going to start looking for either a mobile phlebotomist. Yes, they exist for a fee or go to LabCorp. In my opinion, LabCorp is much better. read more

Quest Diagonistics is a testing facility located on lower 79 ( Temecula Parkway). They take on line appointments as well as walk ins. The facilities are clean and well lit, the staff if friendly and wants to minimize the time it takes to get your test performed. I went in for blood work and was a walk in. It took me about 20 minutes from the time I walked in until I walked out. Their lab results are on time and very detailed. read more

Fu*k this place. This place is horrible for walk in. How they do their walk in is so terrible, what's the point of having it? Appointments is a priority and I don't understand why not take stand in in between some of these appointments. Literally anyone that comes in with an appointment will come and go before you pushing you back for hours regardless how long you been there. I was also next for a stand in and I was skipped for another stand in. Just make an appointment cause they treat walk in like trash. read more

Had an appointment in Temecula Quest. The lab technician, older guy, bald, Louie I believe was his name. This guy needs a lesson in bedside manners, unfriendly. Borderline unprofessional. I left the office with blood running down my arm from the needle location. I was going to return and address, but figured the experience was bad enough to just deal with the blood. Second, they run you thru like cattle,no personality. Poor experience.. read more

Terrible customer service!!! They do not answer phones and when you arrive there is nobody at the front desk. It's a kiosk only and no way to ask any questions. I will not recommend them! read more

I have been to Quest Diagnostics several times in the past three years for Blood Work and have always waited for an hour or so as a walk in. They recommend setting appointments and even tho I have done this we have been informed by a tech you will have to wait another hour we are running late on appointments. Even in the afternoons this is consistent of this company. I recommend Lab Corp. read more

Get ready to wait hours, even with an appointment! The people are very kind, but the company is over scheduling.

We are being called over 20 minutes after his appt if we would be more than 5 min late we would be cancelled. Not sure how or why ppl who checked in after us were called and we are still waiting! Even of their appts were same time we r still waiting!!!!! Go to another quest this one is so unprofessional and has no consideration of your time! read more

Do not come without an appointment and do not come early to an appointment. They say they take walk-ins but a lady was waiting for over 2 hours alone in the waiting room. No human contact at all. When the check-in machine malfunctions.... You are stuck yelling. TV in the waiting room is so loud that I couldn't hear my ear buds. I came early for appointment since I had fasted over 14 hours and was hungry. They did not see me until my appointment time. So frustrating to be starving in the waiting room read more
