Although laboratory-based and point-of-care testing methods are widely used, they require blood collection, trained personnel, and may cause discomfort to participants. Non-invasive spectrophotometric technology has emerged as a potential alternative for rapid hemoglobin assessment without blood sampling.\n\nThis study aims to evaluate the validity and diagnostic performance of a non-invasive hemoglobin using optical method compared with capillary point-of-care testing (POCT) and venous blood hemoglobin measured using an automated hematology analyzer as the reference standard. A total of 150 adults from Kelurahan Kota Bambu, Jakarta, will undergo non-invasive hemoglobin measurement, capillary blood testing, and venous blood testing during a single study visit.\n\nThe study will assess agreement between methods, diagnostic accuracy for anemia detection, and factors that may influence measurement performance. Findings from this study are expected to support the development of convenient, community-based anemia screening strategies and provide evidence for future implementation of non-invasive hemoglobin assessment technologies.",[66],"Anemia",[66,68,69,70,71,72,73,74,75,76,77],"Hemoglobin","Point-of-Care Testing","Hematology Analyzer","Diagnostic Validation'","Diagnostic Accuracy","Anemia Screening","Community Screening","Optical Hemoglobin Measurement","Non-Invasive Hemoglobin Measurement","optical method","NOT_YET_RECRUITING","2026-07-13",{"date":81,"type":82},"2026-07-15","ACTUAL",{"date":84,"type":62},"2026-07-11",{"date":86,"type":62},"2028-07-30",{"name":5,"class":6},1]
