Platelet/Lymphocyte Ratio
The platelet-to-lymphocyte ratio combines platelet and lymphocyte counts from a standard CBC and reflects inflammation and platelet activation. Elevated values have been linked with worse prognosis in several cancers, cardiovascular events, and inflammatory diseases. It complements other simple CBC-derived ratios such as the neutrophil/lymphocyte ratio.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for Platelet/Lymphocyte Ratio. How we verify ranges.
- No stated targetNo separate optimal establishedHigher ratios track inflammation and worse outcomes in cohort studies; no validated target exists
- Lab reference intervalNormal: <180, Elevated: >180What a lab report flags against. A lab interval is not an optimal target.
