Random glucose test (aka causal blood glucose) is a blood sugar test taken from a non-fasting subject.

This test, also called random blood glucose (RBG), assumes a recent meal and therefore has higher reference values than the fasting glucose test.

Reference values[edit]

The reference values for a "normal" random glucose test in an average adult are 79 - 140 mg/dl (4.4 - 6.1 mmol/l), between 140 - 200 mg/dl 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 > 200 mg/dl does not necessarily mean you are diabetic).
