what is glucose level in blood test

Glucose level in a blood test refers to the amount of sugar (glucose) present in your bloodstream at the time of the test. It is a key indicator used to diagnose and monitor diabetes and prediabetes. There are several types of blood glucose tests:

• Fasting Blood Glucose Test: Measures blood sugar after an overnight fast.
• Random Blood Glucose Test: Measures blood sugar at any time, regardless of when you last ate.
• Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after consuming a sugary drink.
• Hemoglobin A1C Test: Provides an average blood sugar level over the past 2-3 months.

Normal blood glucose levels typically range as follows:

Test Type Normal Range

Fasting 70-99 mg/dL
Random Below 140 mg/dL A1C Below 5.7%

If your glucose levels are consistently high, it may indicate diabetes or prediabetes. Consult your healthcare provider for further evaluation and management.
