Question 1

What is a H1c test?

Accepted Answer

The HbA1c (A1c) test measures how much glucose is attached to hemoglobin in red blood cells, reflecting average blood sugar over the past 8–12 weeks. It’s used to diagnose and monitor diabetes and prediabetes; diabetes is typically diagnosed at A1c ≥6.5% and prediabetes 5.7–6.4%. It’s not suitable for detecting short-term glucose changes, pregnancy, or certain hemoglobin variants.

Question 2

What is the viewing angle of Ezviz H1c?

Accepted Answer

The Ezviz H1c uses a wide-angle lens that provides roughly a 110° horizontal field of view (about 120° diagonal). This gives broad room coverage for monitoring a nursery or small room without frequent repositioning. Expect some edge distortion typical of wide lenses; digital zoom crops the image but does not expand the optical coverage.

Question 3

Does ezviz camera have audio?

Accepted Answer

Most EZVIZ cameras include built-in microphones and speakers for two-way audio, allowing live listening, speaking, and optional audio recording. Features vary by model—some offer noise reduction, audio alerts, and the ability to toggle audio in the app—so check the specific model’s specifications and settings to enable or disable audio and comply with local privacy laws.

Question 4

What is the price of Ezviz H4?

Accepted Answer

Ezviz H4 pricing varies by model, region and retailer. Typical retail prices range approximately $120–$220 (roughly ₹10,000–₹18,000) for the standard H4; Pro or kit versions can cost more. Sales, bundles, and local taxes affect final cost—check reliable local retailers or the manufacturer’s store for current pricing and availability. Prices fluctuate frequently.

Question 5

What is normal HbA1c by age?

Accepted Answer

Normal HbA1c is generally <5.7% (below 39 mmol/mol) for children and adults. Prediabetes is 5.7–6.4% (39–46 mmol/mol); diabetes is ≥6.5% (≥48 mmol/mol). Glycaemic targets may be relaxed in older adults: healthy older people often aim <7.5% (58 mmol/mol); those with multiple comorbidities or limited life expectancy may have goals around <8–8.5% (64–70 mmol/mol). Individualize with your clinician.

Question 6

How to reduce HbA1c level?

Accepted Answer

Lower HbA1c by combining consistent lifestyle and medical measures: follow a balanced, portion-controlled diet low in refined carbs; exercise regularly (aerobic + resistance) and aim for weight loss if needed; take diabetes medications or insulin exactly as prescribed; monitor blood glucose and work with your care team; limit alcohol, quit smoking, manage stress and sleep, and attend regular check-ups.

Question 7

What is a normal glycosylated hemoglobin HbA1c level?

Accepted Answer

A normal HbA1c is generally below 5.7% (under 39 mmol/mol). Levels between 5.7% and 6.4% (39–46 mmol/mol) suggest prediabetes, while an HbA1c of 6.5% (48 mmol/mol) or higher on repeat testing indicates diabetes. For people with diagnosed diabetes, treatment targets are often around <7% but should be individualized by age, comorbidities, and hypoglycaemia risk.

Question 8

What should my HbA1c be for my age?

Accepted Answer

For people without diabetes, HbA1c should be under 5.7% (39 mmol/mol); 5.7–6.4% indicates prediabetes. If you have diabetes, most adults aim for about 7.0% (53 mmol/mol) or lower; pregnant women and younger adults may aim for tighter control (~6.5% or below), while older or frail people may have a relaxed target (7.5–8.5%). Individual targets should be set with your clinician.

Question 9

What is the difference between glycosylated hemoglobin and HbA1c?

Accepted Answer

Glycosylated hemoglobin is a general term for hemoglobin chemically bound to glucose. HbA1c is a specific glycated form—the A1c fraction—reported as a percent (or mmol/mol) of total hemoglobin. HbA1c reflects average blood glucose over the past 2–3 months and is the standard test used to diagnose and monitor diabetes; other glycated hemoglobins exist but are less commonly used.

Question 10

What is the HbA1c test in pregnancy?

Accepted Answer

The HbA1c test measures average blood glucose over the past 2–3 months. In pregnancy it’s used early to detect undiagnosed pre‑existing diabetes and to monitor long‑term glucose control. It is not sensitive for diagnosing gestational diabetes, which is usually identified by an oral glucose tolerance test at 24–28 weeks. An elevated HbA1c (commonly ≥6.5%) suggests probable diabetes and warrants specialist care.
