GRBS full form in medical term is General Random Blood Sugar. This is a test to measure the glucose amount in the blood. Regular glucometers can be used for testing the GRBS. This test indicates if the person may have diabetes or not. To measure GRBS, the doctors would prick your finger using the lancet. They will then apply a drop of blood on the testing strip. The testing strip is then inserted in the glucometer to get the reading.
The test should be done at least two hours after the meal. This test also helps people in monitoring their blood sugar throughout the day. Apart from this, the test is mandatory when trying to set the insulin dosage or any other sugar medicine. For the GRBS, the readings should be less than 200 mg/dl. If the reading is over 200, this may indicate diabetes. If your GRBS reading is between 140 and 200, it may suggest that you are prediabetes. So, if you fall into any of these categories, then ensure that you adopt an active lifestyle and you seek medical advice to manage your sugar.
