Results are falsely elevated if the patient is not fasting.  Spectrum Health Laboratories recently updated our system to hard stop a test from being collected if the patient is not fasting. Please remind your patients to fast 8 hours prior to having their blood drawn.

Spectrum Health Laboratories recommends:

• No caloric or caffeine intake for 8-12 hours prior to testing. Do not eat or drink anything except normal amounts of plain water. This also includes no smoking, chewing gum, candy, cough drops, etc.

• Take normal dosages of medications unless the provider has instructed otherwise.
