Random blood sugar

Random glucose test (a.k.a. random blood glucose) is a blood sugar test taken from a non-fasting subject. Random glucose test (a.k.a. random blood glucose) is a blood sugar test taken from a non-fasting subject. This test, also called capillary blood glucose (CBG), assumes a recent meal and therefore has higher reference values than the fasting glucose test. The reference values for a 'normal' random glucose test in an average adult are 79–160mg/dl (4.4–8.9 mmol/l), between 160-200mg/dl (8.9–11.1 mmol/l) is considered pre-diabetes, and ≥ 200 mg/dl is considered diabetes according to ADA guidelines (you should visit your doctor or a clinic for additional tests however as a random glucose of > 160mg/dl does not necessarily mean you are diabetic).
