Fasting Lipid Test Update

Effective August 8th, Spectrum Health Laboratory will ask all patients to indicate how long they have been fasting (regardless of whether they were fasting or not) when they present for Lipid testing.

If fasting is desired; Spectrum Health Laboratory recommends no caloric or caffeine intake for at least 8 hours. The patient is not to drink (other than water), eat, smoke, chew gum, candy, cough drops, etc. for at least 8 hours prior to their blood tests. Prescribed medications are allowed. Continue Reading
