Understanding RBS (Random Blood Sugar)


What is RBS (Random Blood Sugar)?

An RBS (Random Blood Sugar) test measures the level of blood sugar in a person’s blood at any random time of the day. This test is done when you show symptoms of diabetes or to check the response of ongoing treatment if you are already diagnosed with diabetes. It is often done as part of a routine health checkup.

Glucose is the primary energy source for the body, and it is derived from the breakdown of carbohydrates in the food we consume. After the breakdown, glucose is absorbed into the blood and transported to all the body cells for energy. The level of blood glucose is regulated by insulin, a hormone produced by the pancreas. Low levels of insulin or its reduced effectiveness can cause blood glucose levels to rise, and high blood glucose levels can be a sign of diabetes or prediabetes (a condition where a person has high blood glucose levels but not yet at a level that qualifies as diabetes). 

Your doctor may advise an RBS (Random Blood Sugar) test to screen you for diabetes or prediabetes if you show symptoms like fatigue, weight gain/loss, appetite changes, and excessive thirst or urination. Early detection of diabetes allows to prevent complications such as heart disease, kidney damage, and nerve damage. RBS test is also used to check the effectiveness of diabetes medications. 

An RBS test can be done at any time of the day. No special preparation is required before this test; eat and drink as per your routine. However, inform your doctor about all the medications that you take, as some of them may affect your blood glucose levels and need a dose adjustment before the test.

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help them determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, decide whether or not medication will be required to manage your condition, and formulate your overall treatment plan.
