Dr. SpurtiLast Updated on 25th November 2021

A Random Blood Sugar or RBS test is one of the several tests that measure blood glucose levels. An RBS is performed to measure blood glucose levels regardless of when you last ate; random measurements are taken throughout the day to help diagnose diabetes. In a healthy person, blood glucose levels do not fluctuate much, but in a diabetic person, these measurements tend to vary throughout the day.

What is included in an RBS Test?

An RBS test checks for abnormalities in your blood sugar levels regardless of when you last ate; in a healthy person, these levels tend to be less than 140 mg/dL.

A reading between 140 mg/dL and 199 mg/dL indicates prediabetes and reading above 200 mg/dL suggest diabetes.

Sample required for the test

An RBS test checks for abnormalities in your blood glucose levels; the lab technician will collect a blood sample from the vein in your hand in this test. An RBS test takes only a few minutes.

RBS Test Procedure

An RBS test procedure involves drawing a blood sample from your arm.

During the blood test, a phlebotomist will insert a needle into your vein to collect blood. Your blood sample will be collected in a vial or test tube and sent to the lab for further analysis. Like any blood test, you may feel a sting when the needle is injected into your arm, but the pain goes away almost immediately.
A certified Lab Technician (LT) will analyze your blood sample using state of the art technology.
Your blood report will be updated on the MFine app within the next 48 hours after blood sample collection.

How to read the RBS Test report?

Blood glucose levels are measured in milligram per decilitre (mg/dL). A reading lower than 140 mg/dL is considered normal. A reading between 140 mg/dL and 199 mg/dL indicates prediabetes and reading above 200 mg/dL suggest diabetes.

What affects the RBS Test results?

Fasting or non-fasting doesn’t affect an RBS test report. An RBS test can be done at any time of the day to check your blood sugar levels. In healthy persons, their blood sugar levels tend to be lower than 140 mg/dL a couple of hours after eating. A reading between 140 mg/dL and 199 mg/dL indicates prediabetes and reading above 200 mg/dL suggests diabetes.
