The random blood sugar or RBS test is prescribed mainly to check the level of sugar or glucose in the blood for diabetes diagnosis. RBS Test Means: A laboratory blood test to measure the level of glucose in the blood at a given point during the day. Physicians usually utilize the RBS test for screening purposes, particularly during check-ups or emergencies where fasting is not feasible. Simply put, random blood sugar (RBS) is a test that checks your blood glucose level at any time of day, no matter when you last ate. It’s different from fasting blood sugar (which is done after not eating for 8 hours) or post-meal tests. Random means anytime, anyplace —hence the name. Normal blood sugar levels vary throughout the day, influenced by factors such as food intake, physical activity, and stress. The American Diabetes Association provides a general guideline for normal blood sugar levels .
