[ABSTRAK
Latar belakang. Sepsis neonatorum awitan dini (SNAD) adalah sindrom klinisakibat respon sistemik terhadap infeksi pada awal kehidupan. Diagnosis SNADseringkali sulit karena gejala klinisnya tidak spesifik.Tujuan. Mengetahui sensitivitas dan spesifisitas biakan usap telinga dalamdiagnosis SNAD.Metode. Subjek penelitian adalah neonatus yang lahir di RSCM Jakarta dan RSUTangerang Selatan dengan diagnosis SNAD. Dilakukan pengambilan biakan dariusapan telinga dan darah bayi.Hasil. Diantara 50 subjek, terdapat 2 neonatus dengan biakan darah positif, dan 32neonatus dengan biakan usap telinga positif. Hanya 1 subjek yang memilikikesesuaian jenis kuman yang tumbuh dari biakan darah dan biakan usap telinga.Bakteri yang tumbuh pada biakan usap telinga sebagian besar adalah Gram postif(62%). Biakan usap telinga mempunyai sensitivitas 64,7%, spesifisitas 36,4%,nilai duga positif 34,3%, nilai duga negatif 66,6%, rasio kemungkinan positif1,02, rasio kemungkinan negatif 0,97, dan, akurasi 46% untuk mendeteksi SNAD.Simpulan. Ditemukan hasil biakan darah positif pada 2 subjek. Biakan usaptelinga memiliki sensitivitas 64,7%, spesifisitas 36,4%, nilai duga positif 34,3%,nilai duga negatif 66,6%, rasio kemungkinan positif 1,02, rasio kemungkinannegatif 0,97, dan akurasi 46% untuk mendeteksi SNAD.

ABSTRACT
Background. Early-onset neonatal sepsis (EOS) is a clinical syndrome due tosystemic response to infection in early life. EOS is often difficult to diagnosedbecause the clinical symptoms are not specific.Objective. The study aim to determine sensitivity and specificity of ear swabsculture in the diagnosis of EOS.Methods. Neonates born in the CMH Jakarta and Tangerang Selatan Hospitalwho developed sepsis were studied. Swabs were collected for culture from baby’sear. Bacterias isolated from ear swabs cultured were correlated with those fromblood culture.Results. Among 50 neonates studied, 2 neonates had positive blood cultured and32 neonates had positive ear swabs cultured. Only one subject had suitabilitytypes of bacterias that grew from blood and ear swabs. Bacteria grew from earswab cultured were predominantly Gram-positive (62%). Ear swabs cultured hadsensitivity 64.7%, specificity 36.4%, positive predictive value (PPV) 34.3%,negative predictive value (NPV) 66.6%, positive likelihood ratio (PLR) 1.02,negative likelihood ratio (NLR) 0.97, and accuracy 46% to detect EOS.Conclusions. This study showed positive blood culture results were found in twosubjects. Ear swabs cultured had a sensitivity 64.7%, specificity 36.4%, PPV34.3%, NPV 66.6%, PLR 1.02, NLR 0.97, and accuracy 46% to detect EOS, Background.
