What is Random glucose test?

A random glucose test, also known as a random blood glucose test or a casual blood glucose test is a glucose test on the blood of a non-fasting person. This test assumes a recent meal and therefore has higher reference values than the fasting blood glucose test.

Most mentions of capillary blood glucose tests refer to random, nonfasting instances thereof, but the real distinction in that term is capillary blood glucose versus venous blood glucose, arterial blood glucose, or interstitial fluid glucose; any fingerstick or optical transdermal glucose test, fasting or nonfasting, measures capillary blood glucose level.
