<![CDATA[Pneumonia is an acute infection of the lungs caused by microorganisms such as bacteria, viruses, or fungi, which trigger inflammation and weaken the immune system. Early detection is crucial for guiding treatment strategies and reducing the risk of complications. One indicator that can be used for the systemic inflammatory response due to pneumonia infection is the Neutrophil Lymphocyte Ratio (NLR). In addition to NLR, C-Reactive Protein (CRP) levels can also be examined to determine the level of infectious disease activity. This study aimed to assess the correlation between NLR values and CRP levels in pneumonia patients. This is a descriptive correlational study with a cross-sectional design that was conducted on 25 adult and elderly pneumonia patients with comorbidities, selected through consecutive sampling. This research was conducted at Dr. H. A. Rotinsulu Lung Hospital, with the research time being November 6 –18, 2024. The mean neutrophil percentage was 76.9%, lymphocytes 13.4%, NLR 9.12, and CRP level 83 mg/L. Spearman’s correlation test showed a significant positive correlation between NLR and CRP (r=0.415, p=0.039). These results indicate that higher NLR values are associated with increased CRP levels in pneumonia patients.]]>
