I finger prick. I do self-monitoring occasionally with a 5hr OGTT, doing it myself. Since I have done it once before through a lab, and have learned to understand the OGTT curve, I have gone from a sickly 2x flu/year individual to having no fever/flu 20 years running. And Ray Peat's criticism of HbA1c is well stated. What about you?oh I didn't know you were monitoring blood sugars. Are you finger pricking or looking at A1c?
