- KSKatie ShawMar 9, 20261.0I don’t review anything often. However, the staff today 3/9 at Farmington location were very rude and unhelpful. I had to wait FOREVER just to drop off a urine sample. They continued telling me they would “get me next.” The staff acted like I was bothering them when I had a question.🤷🏻♀️ I will have all mine and my families lab requests sent to parkland from this point forward. All of the time waiting just to end up leaving without DROPPING OFF a urine sample.
- CMChris MassieJan 27, 20261.0My wife came here for a routine blood draw. This should be a simple procedure for someone who does it for a living. Instead, her vein was damaged and she ended up with internal bleeding. What made it worse is that the room and overall vibe did not feel sterile or professional for medical procedures. The phlebotomist’s office was decorated with a lot of strange art and there was a strong artificial bubblegum smell. In a medical setting it should feel clean, clinical, and professional. I’m leaving this review both as a warning to others and in hopes Quest management retrains staff and tightens standards at this location.

Frequently Asked Questions About Quest Diagnostics
What do I need to know before I arrive at a Quest Patient Service Center?
Please be aware that when you visit a Quest Patient Service Center:
• Scheduled appointments are strongly encouraged and will receive priority. Please arrive and check in 10 minutes before your appointment time. If you check in more than 10 minutes late for your appointment, you will be served as a walk-in.
• If you walk in, you will have to wait for the next available opening.
Do you accept walk-ins?
Scheduled appointments are strongly encouraged and will receive priority. If you walk in, you will have to wait for the next available opening.
Should I be fasting?
Fasting before a blood draw means you don’t eat or drink anything except water. If your test requires it, don't forget to fast for 8-12 hours before your appointment. If you’re not sure, contact your doctor's office. To learn more about how to prepare for your test, visit QuestDiagnostics.com/patients/get-tested/prepare/fasting for additional fasting information.
What should I bring to my appointment?
Please arrive and check in 10 minutes before your appointment time. If you check in more than 10 minutes late for your appointment, you will be served as a walk-in.
You should bring the following to your appointment:
•A lab order from your doctor. If your doctor did not give you a paper order, check with them to see if they sent it electronically.
•Photo identification listing your first name, last name, and date of birth (for example, a driver's license, government issued photo ID, Passport, or Green Card).
•Current health insurance information.
•Credit, debit, or health savings card. You will be asked to preauthorize payment for any balance due after your insurance is billed.
It’s important to also know if your test requires fasting the day before and/or morning of your appointment. Your healthcare provider should have indicated this on your lab order or during your visit. Learn more about fasting before a lab test.
Note: Childcare is not available and the waiting area is not attended. Some testing protocols, such as drug screenings or pre-employment screenings, have strict rules which do not allow children to accompany the patient during sample collection. If you have questions about your testing protocols, please contact your healthcare professional or employer for additional information.
How do I check in when I arrive?
Sign in using the Check-in kiosk, or if not available, sign the clipboard at the front desk. Please be prepared to present a valid photo ID and insurance information. Be sure to mark the reason for your visit when signing in.
If you were unable to preregister ahead of time, and would like to do so, you may be able to complete the registration process if you arrive a few minutes early at a Quest Patient Service Center that has a Check-in kiosk. When you check in with your mobile number, you may be asked if you want to complete the registration process on your smartphone while you wait.
My doctor told me they would send over an order. Do you have it?
If your doctor said they would send us the order electronically or via fax, there is no need to confirm that we have the order. If we do not have the order, we will call the doctor to obtain it when you arrive at our Quest Patient Service Center. To prevent delays, be sure to visit our location during your doctor’s office hours or obtain a copy of your order from your doctor.
How soon after my visit will my doctor receive my lab test results?
Turnaround times for test results can vary. If you have a MyQuest account, your test results will be delivered to your account as soon as they are available. This can take 2-5 business days from the time the sample is received, depending on your test.
You should always follow up with your doctor to discuss your results.
