Random glucose test - Wikipedia Random glucose test Random glucose test ( ( aka ) 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. Reference values The reference values for a `` normal '' random glucose test in an average adult are 79 -- 160 mg / dl ( 4.4 -- 7.8 mmol / l ), between 160 -- 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 ).
