Methodology · worked example, guidelines & full notes
Lower PNI links to more complications and worse prognosis.
When to use
Predict surgical and oncologic risk from albumin and lymphocytes.
How it works
PNI = 10 × albumin (g/dL) + 0.005 × lymphocyte count (/µL). Onodera cut-offs: > 45, 40–45, < 40.
Key points
- Lower PNI links to more complications and worse prognosis.
- Cut-offs vary by tumour and population.
- Easy to calculate from routine labs.

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Albumin | 4.0 g/dL |
|---|---|
| Total lymphocyte count | 1500 cells/µL |

Frequently asked questions
- What are the limits and cautions when using Prognostic Nutritional Index (Onodera PNI)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does Prognostic Nutritional Index (Onodera PNI) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
