Blood Sugar test is useful to measure levels of glucose present in blood at any given time. Some of the indications of blood sugar test are given below:
- Preventive health check up
- Past history of Diabetes Mellitus
- Family history of Diabetes Mellitus
- Pre-operative health check up
- Metabolic syndrome
In most cases, this test is performed in two parts, and requires two separate blood samples. One of the blood samples required for the test requires patients to have an empty stomach for at least 6-8 hours prior to the test. Therefore, this sample is usually collected in the early hours of morning. This is called the Fasting blood sugar level. Patients are advised to have an early dinner on the previous night. The second sample is collected within 2 hours of having a full meal on the same day. This is the post prandial blood sugar level.
