A member asked:
What is the difference between capillary blood gucose from random venous blood sugar?
A doctor has provided 1 answer
Small difference: CBG is combined arterio-venous blood so the blood sugar from capillaries is a little higher because arteriole blood is more nutrient rich, bringing nutrients to tissues. Venous blood has already been through the capillary system where nutrients/metabolites are "picked up and dropped off. " venous blood has less glucose in it because it is blood carrying away much of what was already metabolized.
