HbA1c: Understanding Your Blood Sugar Average

Disclaimer: This content is informational and does not constitute a diagnosis.

In 30 Seconds

HbA1c reflects average blood sugar over the past 2–3 months. It's a central marker for detecting prediabetes and diabetes.

Useful Thresholds (Reference)

Normal: < 5.7%
Prediabetes: 5.7% to 6.4%
Diabetes: ≥ 6.5% (to be confirmed per medical protocol)

Why Does It Rise?

Excess calories and/or refined carbohydrates
Abdominal fat (insulin resistance)
Lack of activity
Insufficient sleep, chronic stress (indirect effect)

Prevention/Improvement: 3 Effective Levers

After meals: 10–15 min walk (simple, powerful)
Protein + fiber at each meal (slows glucose spike)
Activity: aim for at least 150 min/week + strength training 2 days/week

BioSense — Added Value

FAQ

### Can HbA1c be "false"? Yes: certain anemias/hemoglobinopathies can bias it (discuss with your doctor).

### Prediabetes = diabetes? No, but it's a strong signal: it's often reversible with a consistent strategy.

### How do I import my lab results into BioSense? It's very simple. Once you receive the email from your laboratory, download your report in PDF format. On BioSense, click 'Send my report' and import the file. Our technology automatically analyzes the data to provide you with a clear summary.

### Does BioSense work with all laboratories? Yes, BioSense is compatible with all Medical Biology Laboratories (LBM) operating worldwide. Whether you had your blood test done at a large national network or an independent laboratory, you just need to send us the original PDF.

### Is my health data secure during import? Security is our absolute priority. Your data is hosted on secure servers in Europe, compliant with GDPR standards. BioSense uses complete encryption to ensure your information remains strictly private and confidential.

### What if my report is on paper and not in PDF? For optimal analysis with BioSense, we recommend using the digital PDF file provided by your laboratory on its patient portal. If you only have a paper version, you can scan it cleanly to PDF using your smartphone before importing.
