Hubungan Kadar C- Reactive Protein (CRP) dan Profil Leukosit pada Pasien Sepsis Neonatorum Bayi di Rumah Sakit PKU Muhammadiyah Yogyakarta

Neonatal sepsis is a major factor contributing to morbidity and mortality in newborns. C-Reactive Protein (CRP) and leukocytes are laboratory tests used as indicators of inflammation. This study aims to determine the relationship between C-Reactive Protein levels and leukocyte profiles in neonatal sepsis patients. The research method used was an observational analytic with a cross-sectional approach. Neonatal sepsis at PKU Muhammadiyah Yogyakarta in the period 2021-2026 consisted of 30 samples using a total sampling technique. The distribution of respondents was dominated by male gender compared to female gender, who had a low birth weight <2,500 grams. Based on the study, normal CRP levels were found in 21 respondents, which was caused by a delay in increasing CRP levels. Leukocytes had high levels in 18 respondents. Leukocytes are an initial phase of examination in detecting inflammation that does not require a long time, have several different morphological types in detecting inflammation in the body. This study shows that the most dominant increase in leukocyte levels is found in eosinophils and neutrophils. Based on medical record data at PKU Muhammadiyah Hospital Yogyakarta, analysis using the Spearman correlation test yielded a correlation coefficient of 0.261 with a significance value of 0.164 (p > 0.05). The results showed no significant relationship between the studied variables, with a positive direction and weak correlation strength. The conclusion of this study is that there is no significant relationship between C-Reactive Protein levels and leukocyte profiles in neonatal sepsis patients.
