A random glucose test, also known as a random blood glucose test (RBG test) or a casual blood glucose test (CBG test) is a glucose test (test of blood sugar level) 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 (FBG) test.
Glucose homeostasis, when operating normally, restores the blood sugar level to a narrow range of about 4.4 to 6.1 mmol/L (79 to 110 mg/dL) (as measured by a fasting blood glucose test). [ 10 ] The global mean fasting plasma blood glucose level in humans is about 5.5 mmol/L (100 mg/dL); [ 11 ] [ 5 ] however, this level fluctuates throughout the ...
In non-diabetic patients, there is a modest increase in insulin secretion just before dawn which compensates for the increased glucose being released from the liver to prevent hyperglycemia. However, studies have shown that diabetic patients fail to compensate for this transiently increased blood glucose release, resulting in hyperglycemia.
Fasting prior to glucose testing may be required with some test types. Fasting blood sugar test, for example, requires 10–16 hour-long period of not eating before the test. [1] Blood sugar levels can be affected by some drugs and prior to some glucose tests these medications should be temporarily given up or their dosages should be decreased.

As long as the pancreatic beta cells are able to sense the glucose level and produce insulin, the amount of insulin secreted is usually the amount required to maintain a fasting blood glucose between 70 and 100 mg/dL (3.9–5.6 mmol/L) and a non-fasting glucose level below 140 mg/dL (<7.8 mmol/L).

A non-fasting or random glucose test can be done at any time, with 200 milligrams per deciliter or higher being a red flag for diabetes. Another test is called an oral glucose tolerance test, where a person is given glucose, and then a blood samples are taken at time intervals to figure out how well it’s being cleared from the blood, the most ...
