- JRJason RockMar 17, 20265.0They get it right!
- PMPersesha McdowellMar 13, 20265.0Thank you ladies for being pleasant with good attitudes and having a clean work environment that's always appreciated
- JJJosh JacksonMar 9, 20261.0Automated scheduling is not a one size fits all. I did not use Quest, as I could not speak with a live human. Good luck.
- EPe.a. phillipsFeb 24, 20261.0I have tried getting bloodwork done twice as this place because other sites are far away from where I live and both experiences were bad. There was no wait because I had an appointment, but the first time I went last year, the phlembotomist missed and fished around in my arm, which caused excruciating pain. I went again last week and the initial draw hurt, but because of my first experience, it is difficult to gauge how much it should or should not have hurt. It's almost a week later and I can barely lift the same arm, as it is clear they struck a nerve. Pain is radiating from the site of the draw all the way up into my armpit now and arm hurts to touch.
- MTMichael TafelFeb 21, 20265.0The most expedient quest diagnostics that I have been in. When one comes in the morning, there is parking and little or no line at all therefore an individual someone can come in as a walk in and be served quite quickly. Very easy sign in process. Phlebotomist was professional and an expert. Highly recommend 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.
