About this test
A Random Blood Sugar (RBS) test measures your blood glucose at any time of day, regardless of when you last ate. It is a quick way to screen for diabetes, check for very high or low sugar, and monitor blood-sugar fluctuations.
Clinical significance
A random sugar of 200 mg/dL or more, especially with symptoms, strongly suggests diabetes and should be confirmed with a fasting sugar or HbA1c. Very low readings can indicate hypoglycaemia. Because it isn't standardised to meals, it is best for quick screening rather than formal diagnosis.
