Example
- Involved lymphoid areas
- 4
- Hemoglobin
- 12 g/dL
- Platelet count
- 150 ×10⁹/L
Result: Binet stage B — 4 involved areas, counts preserved.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Stages
- A: < 3 areas, Hb ≥ 10, platelets ≥ 100; B: ≥ 3 areas, counts preserved; C: Hb < 10 and/or platelets < 100.
- Areas
- Five lymphoid areas: cervical, axillary, inguinal nodes, spleen, liver.
What you enter
- Involved lymphoid areas (0–5)
- Hemoglobin
- Platelet count
