<![CDATA[ABSTRACT Sepsis neonatorum is one of the biggest triggers of neonatal deaths in Indonesia. The Diagnosis of sepsis is difficult to establish due to non-specific symptoms, so accurate, affordable, and easily accessible biomarkers are needed. Commonly used biomarkers such as C-Reactive Protein (CRP) and Procalcitonin (PCT) have limited cost and availability. Neutrophil lymphocyte Ratio (NLR) is a promising alternative because it can be obtained from a routine complete blood count. The study intends to determine the correlation between the value of NLR and CRP in children indicated sepsis in RSUD dr. Sayidiman Magetan. The study was classified as cross sectional based analytical observational in 33 pediatric patients suspected of sepsis during October 2024 to March 2025. Spearman correlation testing is used in the data analysis of this study because the distribution of data is not normal based on the Shapiro-Wilk test. The average value of NLR was 6.72% and CRP was 70.16 mg/L. Spearman correlation test results showed a moderate correlation between NLR and CRP with a correlation coefficient of 0.407 (p = 0.019). There is a significant moderate correlation between NLR and CRP in pediatric patients with suspected sepsis, so NLR can potentially be used as an alternative inflammatory marker to detect pediatric sepsis. ABSTRAK Sepsis neonatorum ialah satu di antara pemicu terbesar terhadap kematian neonatal di Indonesia. Diagnosis sepsis sulit ditegakkan karena gejala yang tidak spesifik, sehingga dibutuhkan penanda biologis (biomarker) yang akurat, terjangkau, dan mudah diakses. Biomarker yang umum digunakan seperti C-Reactive Protein (CRP) dan Procalcitonin (PCT) memiliki keterbatasan biaya dan ketersediaan. Rasio Neutrofil Limfosit (Neutrophil Lymphocyte Ratio/NLR) menjadi alternatif yang menjanjikan karena dapat diperoleh dari hitung darah lengkap rutin. Penelitian bermaksud mengetahui korelasi antara nilai NLR dan CRP pada anak terindikasi sepsis di RSUD dr. Sayidiman Magetan. Penelitian tergolong observasional analitik berbasis cross sectional pada 33 pasien anak suspek sepsis selama Oktober 2024 hingga Maret 2025. Pengujian korelasi Spearman dimanfaatkan dalam analisis data penelitian ini sebab distribusi data tidak normal berdasarkan uji Shapiro-Wilk. Nilai rata-rata NLR sebesar 6,72% dan CRP sebesar 70,16 mg/L. Hasil uji korelasi Spearman menunjukkan adanya korelasi sedang antara NLR dan CRP dengan koefisien korelasi sebesar 0,407 (p = 0,019). Terdapat korelasi sedang yang signifikan antara NLR dan CRP pada pasien anak suspek sepsis, sehingga NLR berpotensi digunakan sebagai penanda inflamasi alternatif untuk mendeteksi sepsis anak.]]>
