I'm trying to requalify for a lower premium life insurance policy which means
I have to submit to a blood test that a visiting nurse extracts. They told me
I don't have to fast . I'm used to fasting for my annual physical but now
can't remember which tests are affected by fasting and which aren't.
They also want a urine sample......is there a fasting/non-fasting effect on
test for that?

For some reason, my doctor hasn't required urine samples for many yrs, just blood. What tests need urine samples ?
 
Urine samples for drug testing, as well as for glucose in the urine (you don't want that to be happening) I imagine.

Seems they would want a fasting test if they were interested in cholesterol, blood glucose, or A1c. Wouldn't need to fast if they were looking for CRP, liver function and kidney function, I don't think.

You might want to ask what they are looking for.

LDL cholesterol, triglycerides, and glucose are the major tests requiring fasting. The urine sample is to check for drug metabolites including cocaine, among other things. Routine urinalysis is not necessarily a recommended test in healthy patients for screening purposes.
 
Thanks, Rich and Rambler. Think I'll try to get an AM appt and fast.
For free labs, might as well get an accurate result.
