Random Blood Glucose Test
The random blood glucose test measures the blood glucose level any time of day without regard to drinking or eating. This test is sometimes referred to as a random plasma glucose test, or a casual plasma glucose test.
Test Procedure
A healthcare provider will take a single sample of your blood and send it to a lab to be analyzed.
Test Results
A random blood glucose level of 200 mg/dL (which means 200 miligrams of glucose for each deciliter - or 1/10th liter - of blood) or higher with diabetes symptoms means it's likely you have diabetes. The doctor will confirm the diagnosis with an additional test, often a fasting plasma glucose test, or fasting blood glucose test. Your doctor may confirm all abnormal tests with a second test before diagnosing diabetes.
