- AMA. MooreMar 18, 20265.0The Quest Website which I typically use to schedule my appointment said there were no appointments within any locations of 50 miles of me. I went to my usual location in South Park Business Center, Littleton, and was able to do a walk-in appointment within about 10 or 15 minutes. The lady that handled the blood draw was very good.
- CLC LMar 12, 20261.0NO customer service - nobody answers the phone or addresses clients in the waiting room. Over 20 mi. Late for a scheduled appointment
- GDGerry DyeMar 11, 20265.0The PSC was very nice and the Phlebotomist was friendly and professional. Not like my experience with the other major lab in Denver.
- ABAmber BeachFeb 18, 20265.0While usually crowded, I landed on a day without a line and the phlebotomist got me taken care of immediately and was one of the easiest blood draws I’ve had.
- LFLaurie FreyaFeb 13, 20265.0I arrived a little early for my appointment and was seen within a couple of minutes. It was very refreshing to have an appointment time honored! The office was a little difficult to find because there's a big sign above the door that says Optum, but if you look carefully, there's a paper sign taped to the window that tells you there are a couple of other businesses through the entrance, including Quest.
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.
