Question: Fasting Blood Work

 SunnyMA - Thu Aug 25, 2005 10:01 pm

Hi. Can anyone tell me which common blood tests you need to fast for and for how long? Any help is very much appreciated.

Hi SunnyMa,
I'm a Medical Technologist and our lab policy requires a 12 hour fast for Lipids which include Cholesterol, Triglyceride and HDL (high density lipoprotein). Also CMP (Complete Metabolic Profile) and BMP (Basic Metabolic Profile) both test for Glucose (blood sugar) and many physicians want to evaluate a fasting glucose. I usually tell patients that it never hurts to fast. (Some disagree when they're hungry, ha! ha!). Fasting also means no coffee which seems to be the hardest for some people.

Hope this helps,
