Neutrophil-Lymphocyte, Platelet-Neutrophil, and Platelet-Lymphocyte Ratios as Indicators of Sickle Cell Anaemia Severity.

Background: Sickle cell anaemia (SCA) imposes a substantial healthcare burden, affecting millions of people worldwide. Understanding the determinants influencing SCA severity is crucial for enhanced disease management and optimized patient outcomes. This study aimed to investigate the relationship between Neutrophil-Lymphocyte Ratio (NLR), Platelet-Neutrophil Ratio (PNR), Platelet-Lymphocyte Ratio (PLR), and SCA severity.
