Random Blood Sugar (RBS)

The Random Blood Sugar (RBS) Test is a simple blood test used to measure glucose (sugar) levels in your blood at any time of the day, without the need for fasting. It is commonly used as a screening tool for diabetes or to check blood sugar fluctuations in people already diagnosed with diabetes.

Uses of the RBS Test

• Detect high or low blood sugar levels at any time
• Screen for diabetes and prediabetes
• Monitor blood sugar in patients with diabetes
• Identify sudden fluctuations in glucose levels
• Help doctors adjust medications, diet, and insulin in diabetic patients
