The Platelet/Lymphocyte Ratio is a significant biomarker that combines information about platelets and lymphocytes, two critical components of the blood. This ratio is increasingly recognized for its potential role in prognostic assessments across various medical conditions, including inflammatory diseases, certain cancers, and cardiovascular conditions. To use this calculator, input the platelet and lymphocyte counts obtained from a complete blood count (CBC) test. Our calculator will compute the PLR, offering a valuable metric for understanding the balance between platelets (involved in clotting and inflammation) and lymphocytes (key players in the immune system). This tool is particularly useful for healthcare professionals in assessing disease severity, prognosis, and treatment response. It's also a helpful resource for individuals keen on understanding more about their health, particularly in the context of inflammation and immune function. By providing insights into the Platelet/Lymphocyte Ratio, our calculator assists in more informed health monitoring and decision-making in clinical settings and personal health management.
