PLR is a CBC-derived biomarker calculated by dividing platelet count by absolute lymphocyte count. It is used as a non-specific adjunct marker of inflammatory and physiologic stress across multiple clinical contexts.
Formula: PLR = Platelet count / Absolute Lymphocyte Count.
Higher PLR values may reflect increased inflammatory activity or physiologic stress in many conditions.
Use PLR as an adjunct trend marker when CBC data are available and inflammatory burden is being tracked.
PLR is non-specific and influenced by infection, medications, hematologic conditions, and chronic inflammatory states. It is not a standalone diagnostic tool.

Calculate NLR from absolute neutrophil and lymphocyte counts as an inflammatory and prognostic marker.
HematologyEstimate overt disseminated intravascular coagulation probability using the ISTH scoring framework.
HematologyCalculate the 4T score for heparin-induced thrombocytopenia (HIT) pretest probability. Score ≤3: >99% NPV for HIT. Intermediate/High (≥4): stop heparin, start alternative anticoagulation.
EmergencyCalculate qSOFA bedside sepsis risk score. A score of 2 or more (altered mentation, RR ≥22, SBP ≤100) flags high-risk infection requiring urgent evaluation.
