Random Blood Glucose Test (RBG)

Random Blood Glucose test is a type of blood test that measures the glucose level in the blood. Random Blood Glucose does not require the pre-preparation of patients. You can give blood at any time of the day. You don’t have to take fasting like other tests. If you have symptoms of high blood glucose, take this test as a part of a routine preventive health check-up.

Random glucose testing and disease management

In non-diabetic adults, the actions of our internal insulin and the body’s use of sugar for energy control glucose levels. If they received random glucose tests throughout the day, their glucose levels would remain relatively stable.
In people with diabetes and prediabetes, glucose levels can vary widely during the day. It will be true if the disease is not controlled well. In these people, random test results will vary widely. Tests may also be consistently high.

What happens during a Random Blood Glucose Test?

During a Random Blood Glucose Test, a lab technician will collect blood from a vein, typically from the inside of your elbow or from the back of your hand. The test will take only a few minutes. The technician:

• Cleans your skin with an antiseptic wipe
• Places an elastic band, or tourniquet, around your upper arm to help the vein swell with blood
• Inserts a needle in your vein and collect a blood sample in one or more vials
• Removes the elastic band
• Covers the area with a bandage to stop any bleeding
• Place a barcode on your blood sample vial and send them to a lab for analysis

A blood test can be slightly uncomfortable. When the needle punctures your skin, you might feel a prick or pinching sensation. Some people also feel faint or light-headed when they see blood. Afterward, you may have minor bruising, but it will clear up within a few days.
