what is hemoglobin test used for

The hemoglobin A1C (HbA1c) test is primarily used for:

• Diagnosing Diabetes and Prediabetes: It measures your average blood sugar levels over the past 2-3 months, helping to diagnose type 2 diabetes and prediabetes.
• Monitoring Diabetes Management: For individuals with diabetes, the A1C test helps track how well blood sugar levels are being controlled over time.
• Assessing Risk: It can also be used to assess the risk of developing diabetes-related complications.

Key A1C Ranges:

A1C Level Diagnosis

Below 5.7% Normal 5.7% - 6.4% Prediabetes 6.5% or above Diabetes

This test is particularly useful because it provides a long-term view of blood sugar levels, unlike daily glucose tests which only show a snapshot.
