Understanding Hemoglobin A1C (HbA1c) Test from Experts

The hemoglobin A1C (HbA1c) test is a blood test that provides information about your average blood sugar level over the past 3 months. The higher your HbA1c level, the more sugar has been sticking to your red blood cells, which indicates that you have diabetes or prediabetes.

The American Diabetes Association (ADA) recommends that all adults aged 45 years and older be screened for diabetes every 3 years. The ADA also recommends that adults aged 20–45 years with one or more risk factors for type 2 diabetes be screened every 3 years. Risk factors for type 2 diabetes include being overweight or obese, having a family history of diabetes, being inactive, feeling stressed out all the time,

Hemoglobin A1C (HbA1c) is a blood test that provides information about your average blood sugar level for the past 3 months.

The HbA1c test is used to diagnose diabetes and prediabetes, to monitor blood sugar control in people with diabetes, and to screen for diabetes in people who do not have symptoms. The test can also be used to monitor the effects of treatment for diabetes.

Normal levels are between 4 and 5.6% of hemoglobin.

The HbA1c test is a blood test used to measure a person's average blood sugar level over the past 2 to 3 months. The higher the HbA1c level, the greater the risk of developing diabetes and other health problems.

The main use of the HbA1c test is in diagnosing diabetes, as it can show if blood sugar levels are too high over time. The test can also help gauge how well a person's diabetes treatment plan is working.

Endocrinologist 3

The hemoglobin A1C (HbA1c) test is a blood test that measures the percentage of glycated hemoglobin in your blood.

Glycated hemoglobin is formed when glucose (sugar) sticks to the hemoglobin molecule in your red blood cells. The higher your blood sugar levels are, the more glycated hemoglobin will be formed.

The HbA1c test can be used to monitor your blood sugar control over time. A result of 6% or less indicates good control, while a result of 7% or more indicates poor control.

Endocrinologist 4

Hemoglobin A1C (HbA1c) is a blood test that provides information about your average blood sugar level over the past 2-3 months. It measures the percentage of glycated hemoglobin in your blood. Hemoglobin is a protein in red blood cells that carries oxygen to the body's tissues. Glycation is a chemical reaction that occurs when glucose (sugar) binds to hemoglobin.

The higher your HbA1c level, the higher your average blood sugar has been over the past few months. An HbA1c level of 6.5% or higher on two separate tests means you have diabetes. An HbA1c level of 5.7% -

The Hemoglobin A1C (HbA1c) Test is a blood test that measures the percentage of glycated hemoglobin in your blood. It's used to determine how well your diabetes is controlled over time.

If your HbA1c level is 7% or higher, it means that you have uncontrolled diabetes. If it's less than 7%, it means that you have controlled diabetes. The test can also be used to diagnose diabetes, because a diagnosis of diabetes is made when an HbA1c level of 6.5% or higher is found.

Endocrinologist

Hemoglobin A1C (HbA1c) is a blood test that shows the average amount of sugar (glucose) in your blood over the past 2 to 3 months

The HbA1c test is used to diagnose type 2 diabetes and prediabetes, and to monitor diabetes treatment. The American Diabetes Association (ADA) recommends that people with diabetes have an HbA1c test at least twice a year.

Endocrinologist 6

The hemoglobin A1C (HbA1c) test is a blood test used to screen for and diagnose diabetes and prediabetes. The HbA1c test measures the percentage of glycated hemoglobin in the blood. Hemoglobin is a protein found in red blood cells that carries oxygen from the lungs to other parts of the body. Glucose, a type of sugar, attaches to hemoglobin to form glycated hemoglobin. The higher the level of glycated hemoglobin, the higher the level of glucose in the blood.

The HbA1C test can be used to:

Screen for diabetes and prediabetes

Diagnose diabetes

Monitor blood sugar control in people

Endocrinologist

The HbA1c test is a blood test that measures your average blood sugar level over the past 2-3 months. This test is used to diagnose type 2 diabetes and prediabetes, and to monitor blood sugar levels in people with diabetes.

Higher than normal levels of hemoglobin A1c indicates that you have diabetes or prediabetes. Levels of 6.5% or higher indicate diabetes, while levels between 5.7% and 6.4% indicate prediabetes. Normal levels are below 5.6%.

Wearable Health Monitoring India Market: Tracking Wellness & Chronic Care | SecondMedic

In India, wearable health monitoring is no longer a nice-to-have accessory - it’s becoming central to how people manage wellness, chronic conditions and preventive care. With the rise of lifestyle diseases, increasing smartphone penetration and growing consumer health awareness, the wearable health monitoring market is gaining serious momentum.

Market Size & Growth Outlook

According to a detailed study, the Indian wearable medical devices market generated approximately USD 2,344.5 million (USD 2.34 billion) in 2024 and is projected to reach USD 5,670.6 million by 2030, growing at a compound annual growth rate (CAGR) of about 16?tween 2025 and 2030. Grand View Research
Another research source puts the medical wearables market in India at USD 1.04 billion in 2024, forecast to reach USD 4.20 billion by 2033 at ~15.5?GR. IMARC Group

These figures underscore a major shift: wearables are becoming an integral part of India’s health-tech ecosystem - not just fitness gadgets, but devices capable of monitoring heart-rate, sleep, activity, arrhythmia, vitals, and enabling remote patient monitoring.

Why This Growth Is Happening

Chronic disease burden: With rising incidences of diabetes, hypertension, cardiovascular disease and obesity, there’s a greater demand for continuous monitoring and early alerts.
Digital health push: Government programmes like the National Digital Health Mission (NDHM) and greater smartphone/internet penetration support connected health solutions.
Consumer awareness & wellness culture: More Indians are adopting health-tech and wearables as part of lifestyle, not just for tracking steps but for meaningful health insights.
Home-based care & remote monitoring: The pandemic accelerated acceptance of home-based diagnostics and monitoring - making wearables more relevant for remote care models.
Device innovation & cost reduction: Improved sensors, cheaper manufacturing and localised device assembly are easing access and lowering barriers for adoption.

Segmentation & Key Areas of Impact

Product type: Smartwatches, fitness bands, smart rings, medical-grade monitors for vitals, remote patient monitoring sensors. For instance, the broader smart wearable market in India shows health & fitness tracking made up ~54.35% of the market in 2024. Mordor Intelligence+1
Application: Chronic disease monitoring, preventive wellness, senior care, remote patient monitoring. The largest revenue segment in 2024 is chronic disease management. Grand View Research
Geography & access: Urban metros lead adoption today but Tier-2/3 towns and rural areas represent the next frontier, especially when paired with telehealth and wearable-data integration.

How SecondMedic Fits In

At SecondMedic, we believe monitoring is as important as diagnostics - and wearables are key to that vision. Our platform integrates wearable-generated data into our digital health ecosystem so we can provide:

Continuous monitoring for individuals managing chronic conditions - enabling earlier interventions when trends suggest risk.
Preventive insights for health-conscious users - wearable data feeds into our dashboards to flag deviations and prompt doctor consults.
Remote care models for seniors or mobility-limited users - wearable alerts tie into tele-consultation and remote monitoring workflows.

By combining wearable health monitoring with virtual consultations, diagnostics and preventive screening, SecondMedic offers a holistic digital health solution - not just episodic care but continuous well-being.

Challenges Ahead

Despite strong growth, wearable health monitoring in India faces some headwinds:

Affordability & accessibility: While top-tier wearables are affordable for many urban users, the device cost and ecosystem (apps, data, follow-ups) can be a barrier for rural and lower-income groups.
Device accuracy & clinical validation: Consumer-grade wearables may lack medical-grade accuracy. For serious clinical usage, device certification and integration with health records are required.
Data integration & usability: Wearable data alone isn’t enough - it needs to be integrated into clinical workflows, trusted by doctors and actionable.
Digital literacy & internet/connectivity: Rural areas and older populations may face challenges using wearables effectively or syncing data.
Regulatory and privacy issues: With health data being sensitive, wearables must ensure strong data security, interoperability and comply with frameworks like NDHM.

Real-World Calculation & Uptake Example

If the market grows from USD 2.34 billion in 2024 to USD 5.67 billion by 2030, that’s roughly a 2.4× increase in six years.
At 16?GR, wearable adoption is expected to double approximately every 4.5 years.
If chronic disease monitoring is the largest segment today, then targeting those affected by diabetes/hypertension (over ~100 million Indians) gives enormous addressable potential for wearable monitoring + telehealth.
For SecondMedic platform users: even if 1% of chronic-disease patients adopt wearables and remote monitoring via our service, that could represent hundreds of thousands of people nationwide - driving meaningful growth in preventive care utilisation.

Looking Ahead

As sensors get cheaper, wearables become more accurate and integrated with digital health platforms, we expect:

Wearables prescribed by doctors as part of home-care plans for chronic patients.
Insurance-linked models where usage of wearables triggers incentives or premium discounts.
Data ecosystems where wearable telemetry flows into platforms like SecondMedic, enabling predictive analytics, alerts and personalised care.
Greater rural uptake with low-cost devices, smartphone penetration and telehealth coupling.

Conclusion

The wearable health monitoring market in India is at an inflection point - moving from fitness gadgets to serious health-tech tools.
For health platforms like SecondMedic, this is a major opportunity: wearable data becomes another input in delivering continuous, personalised, preventive and remote care.

Because health isn’t just about testing now - it’s about monitoring, tracking, and intervening early.
