Akurasi Pengukuran Kadar Hemoglobin Menggunakan Alat SD Biosensor Standard G6PD Analyzer sebagai Point-Of-Care pada Populasi Anak di Wilayah Endemis Malaria

Abstract

Background: Malaria remains a significant public health concern, particularly in endemic regions, is frequently associated with anemia in children. Accurate hemoglobin measurement is crucial for diagnosing anemia, especially in resourcelimited settings. This study compares the accuracy of SD Biosensor Standard G6PD Analyzer with Hemocue HB301 System for hemoglobin measurement among children in malaria-endemic areas. Objective: To determine the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+), negative likelihood ratio (LR-), pretest odds, post-test odds, and overall accuracy of the SD Biosensor Standard G6PD Analyzer compared to the Hemocue HB301 System. Method: This cross-sectional diagnostic study involved 325 children aged 6-18 years in Kualuh Leidong District. Secondary data were obtained from a previous study conducted in August 2024, using a total sampling technique. Result: The mean hemoglobin level measured by SD Biosensor Standard G6PD Analyzer (14,22±2,21 mg/dL) was higher than that measured by Hemocue HB301 System (13,45±1,63 mg/dL), with significant difference (p=0,001). The prevalence of anemia detected by SD Biosensor and Hemocue was 12,3% and 11,4%, respectively. The SD Biosensor Standard G6PD Analyzer demonstrated a sensitivity of 70,27%, specificity of 95,14%, PPV of 65%, NPV of 96,14% and an overall accuracy of 92,31%. Conclusion: The SD Biosensor Standard G6PD Analyzer exhibited relatively low sensitivity but high specificity compared to Hemocue HB301 System in measuring hemoglobin levels among children in malaria-endemic areas. Further research is needed to compare both devices against the gold-standard automated hematology analyzer and to identify the factors influencing measurement accuracy.
