Blood Testing Lab

Patients are seen in the order in which they arrive; patients who need immediate testing, timed tests, or patients with special needs may be seen first. The majority of blood tests do not require an appointment. Your doctor should tell you if you have an appointment with the lab or need to make one.

If you would like to review a list of lab tests that require an appointment or need to be collected at a particular lab location, download Special Test Considerations.

When you arrive at one of The UVM Medical Center's lab locations, please stop in at the patient registration area before proceeding to the laboratory. The UVM Medical Center offers three convenient lab locations for walk-in appointments with free parking.

Off-Hours Blood Drawing

Routine blood drawing is available during the hours listed above. If your doctor has instructed you to get your blood drawn urgently, or if the testing required is a timed draw not within routine lab hours, please visit The UVM Medical Center's Main Campus in Burlington. Please stop by Registration, Main Pavilion, Level 3 (street level) before proceeding to the laboratory, and a phlebotomist will be paged.

Blood Test and Fasting

How long do I have to fast for before a blood test?

  • If a fasting blood test is ordered, you should not have anything to eat or drink (except water) for at least eight hours. This usually involves an overnight fast.
  • You should continue to take any prescription medications unless your physician directed you not to take them.
  • Smoking and exercise may affect your results as well, so you should refrain from these activities as much as possible during this time.

If you have any concerns about refraining from food for this period of time, talk to your physician.

Lab Testing Results

For your security, The UVM Medical Center Department of Pathology and Laboratory Medicine does not currently release test results to patients. You must contact your physician for laboratory test results or sign up for MyHealth Online. If you have questions about lab testing, please contact The UVM Medical Center Laboratory Customer Service by e-mail, or by phone at 802-847-5121 or 800-991-2799.

All our sample collection technicians (phlebotomists) are nationally certified.
