The Relationship Between Widal Agglutination Titer Categories and Neutrophil-to-Lymphocyte Ratio in Patients with Acute Fever

Background

Acute fever is a common clinical condition caused by various infectious agents, including Salmonella Typhi. The Widal test is widely used to support typhoid diagnosis because it is simple, rapid, and inexpensive, although its diagnostic accuracy is limited. The Neutrophil-Lymphocyte Ratio (NLR) is a hematological parameter reflecting systemic inflammation. This study aimed to determine the relationship between Widal agglutination titer categories and NLR in patients with fever Methods : This observational analytical study used a cross-sectional approach. Secondary data were obtained from medical records and laboratory results. A total of 134 patients with fever were selected using purposive sampling. Widal titers and neutrophil and lymphocyte counts were recorded, and NLR was calculated by dividing the neutrophil count by the lymphocyte count. Data were analyzed using Spearman’s correlation test at 0.05.
