The HbA1c test, also known as Glycated Hemoglobin test, measures the average blood sugar levels over the past 2 to 3 months. It evaluates the percentage of hemoglobin in the blood that is coated with glucose.
Unlike a single fasting or random blood sugar test, HbA1c provides a long-term picture of blood glucose control. It is widely used to diagnose diabetes, identify prediabetes, and monitor glucose management in individuals with known diabetes.
Because red blood cells live for approximately 90 to 120 days, the HbA1c test reflects sustained blood sugar exposure over time.
An HbA1c test helps:
● Diagnose type 2 diabetes
● Detect prediabetes early
● Monitor long-term blood sugar control
● Assess risk of diabetes-related complications
● Evaluate effectiveness of diabetes treatment
Maintaining optimal HbA1c levels reduces the risk of complications affecting the heart, kidneys, nerves, and eyes.
An HbA1c test is recommended for individuals who require reliable long-term glucose assessment with convenient home sample collection and secure reporting.
You may consider booking your HbA1c test with SecondMedic if you:
● Experience symptoms such as increased thirst, frequent urination, or unexplained weight changes
● Have a family history of diabetes
● Are overweight or physically inactive
● Have high blood pressure or high cholesterol
● Are monitoring existing diabetes
● Prefer certified laboratory testing with doorstep collection
SecondMedic facilitates HbA1c testing through NABL accredited laboratories using standardized glycohemoglobin assay techniques to ensure clinically dependable results.
The HbA1c test measures:
Glycated Hemoglobin Percentage
This represents the proportion of hemoglobin molecules that have glucose attached.
In some reports, the following may also be provided:
Estimated Average Glucose (eAG)
An approximate average blood sugar level derived from the HbA1c value to help patients understand results in daily glucose terms.
The test requires a simple blood sample collected from a vein.
Typical reference values are:
● Below 5.7% – Normal
● 5.7% to 6.4% – Prediabetes
● 6.5% or higher – Diabetes
For individuals with diagnosed diabetes, target HbA1c levels are usually individualized based on age, overall health, and medical history.
Interpretation should always be done by a qualified healthcare professional.
Fasting is not required for an HbA1c test.
You can eat and drink normally before sample collection. This makes the HbA1c test convenient for routine monitoring without scheduling dietary restrictions.
● No special preparation is generally required
● Inform your doctor about diabetes medications
● Stay hydrated before sample collection
● Continue regular diet unless instructed otherwise
The blood collection process typically takes only a few minutes.
HbA1c testing performed in NABL accredited laboratories uses standardized high-performance liquid chromatography (HPLC) or immunoassay methods to ensure precision and reliability.
However, certain conditions such as anemia, recent blood transfusion, or hemoglobin variants may influence results. Clinical correlation is recommended for accurate interpretation.
Repeat testing may be advised to confirm abnormal findings.
The HbA1c test price in India generally ranges between ₹400 to ₹1000 depending on the city, laboratory network, and home collection availability.
The price typically includes:
● Blood sample collection
● Laboratory processing
● Digital report delivery
Home sample collection may be available at no additional cost in select cities.
HbA1c can indicate elevated blood sugar levels but does not differentiate between type 1 and type 2 diabetes. Additional clinical evaluation and specific antibody testing may be required for classification.
Yes. Certain types of anemia or conditions affecting red blood cell lifespan can alter HbA1c values. Your doctor may recommend alternative tests if necessary.
HbA1c is not typically used to diagnose gestational diabetes. An oral glucose tolerance test is usually preferred during pregnancy.
HbA1c reflects long-term glucose control and does not change rapidly within a few days. Significant changes usually occur over weeks to months.
Regular physical activity contributes to improved long-term glucose control, but it does not cause immediate changes in HbA1c levels.
In early stages of glucose imbalance, discrepancies may occur. Your doctor may evaluate both HbA1c and fasting glucose levels for comprehensive assessment.
Yes. It is a routine blood test and safe for individuals across all age groups.
Individuals with diabetes are typically advised to test every 3 to 6 months, depending on glucose control and treatment plan.
