Why Use Health Numbers
- Free & no install — use it straight from your browser with no sign-up or app.
- No data collected — every result is computed in your browser; your input never leaves your device.
- Standard charts — based on widely used classification charts such as ACC/AHA, ADA and WHO/Asian-Pacific criteria.
- Transparent basis — each tool shows the classification table, the interpretation rules and reference sources.
Each result is a reference estimate, not a diagnosis. If you have symptoms or your numbers fall outside the normal range, consult official sources such as the CDC and talk to a healthcare professional.
