Example
- Age
- 60 years
- Spleen
- 10
- Platelet count
- 400 ×10⁹/L
- Peripheral blasts
- 5 %
- Peripheral eosinophils
- 5 %
- Peripheral basophils
- 5 %
Result: Hasford score 1789 — high risk.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Risk
- Low ≤ 780, intermediate 781–1480, high > 1480. An older comparator to Sokal.
What you enter
- Age
- Spleen (cm below costal margin)

- Peripheral basophils
How this is calculated
- Formula
- (0.6666×[age>50] + 0.0420×spleen + 0.0584×blasts + 0.0413×eosinophils + 0.2039×[baso>3%] + 1.0956×[plt>1500]) × 1000.
