Please stop by Registration, Main Pavilion, Level 3 (street level) before preceeding to the laboratory, and a phlebotomist will be paged.

Fasting Before Blood Test

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 8 hours. This usually involves an overnight fast. You should continue to take any medications that have been prescribed for you, unless directed not to by your physician. 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 going without eating for this period of time, please discuss with your physician.

Common Blood Tests

What blood lab tests do you offer?
Fletcher Allen Laboratory services offer hundreds of types of diagnostic lab tests. Some of the common blood tests offered include: Complete Blood Count (CBC), Red Blood Cell Count (RBC), White Blood Cell Count (WBC), Blood Lead Testing, Lipid Profile (LDL, HDL and Total Cholesterol) Testing, A1c Test, Lactose Intolerance Test, and Thyroid (T3, T4, and TSH) Testing.
