Complete the fields above to see the result.
When to use
- Prognostic stratification in solid-organ cancers (originally validated in inoperable non-small-cell lung cancer) using two routine blood tests.
Formula
GPS = 0 if CRP <=10 mg/L and albumin >=3.5 g/dL; 1 if either CRP >10 mg/L or albumin <3.5 g/dL; 2 if both CRP >10 mg/L and albumin <3.5 g/dL.
Pearls and pitfalls
- The modified GPS (mGPS) scores 0 for CRP <=10 mg/L regardless of albumin - the two versions differ in patients with isolated hypoalbuminemia.
