Re: What is considered fasting?
If you were going just for a fasting glucose (blood) test, then 8 hours fasting is required. If your blood work includes testing for cholesterol (LDL, HDL, Triglycerides, et al), then 12 hour fasting is required.
Since I get those and some others done regularly every three months, I get the whole shebang on one reqisition, so I fast for 12 hours.
P.S. I asked last time why there was a difference and the nurse said the cholesterol test requires 12 hours fasting.
Hope this helps :-)
