Fasting Blood Glucose (FBG) Test

The Fasting Blood Glucose (FBG) Test at Pamel Laboratories is a simple yet critical test that measures the level of glucose (sugar) in your blood after an overnight fast (8–12 hours without food or drink except water). It is primarily used to screen for and monitor diabetes mellitus, pre-diabetes, and other blood sugar disorders.

This test helps detect abnormal blood sugar levels early, allowing for timely intervention through lifestyle changes or medication.

What the Test Measures:

• The concentration of glucose in the bloodstream under fasting conditions

• Indicates how well your body regulates blood sugar

  • Type 1 and Type 2 diabetes

  • Pre-diabetes

  • Hypoglycemia (low blood sugar)
