Special diet before GTT or not?
Ok I'm confused. I've read in some places that people have to do a special 3 day diet before doing the 2 hr fasting glucose tolerance test. I've just found out I have to do the 2 day GTT after failing the screening, but have had no instruction re diet. I'm gonna call in the morning (hoping I can just go in and do it tomorrow & get the darn thing out of the way). But I'm really wondering what is the deal with the 3-day diet? Is it really necessary?
FYI I'm doing the test through Dorevitch.
