Malaria remained a leading cause of morbidity and mortality in endemic regions, with prompt and accurate diagnosis critical for effective case management. Rapid diagnostic tests have emerged as point-of-care tools that enable community health workers to diagnose malaria in resource-limited settings where microscopy is unavailable. This review examined the diagnostic performance characteristics of rapid diagnostic tests for malaria and evaluated the effectiveness of treatment algorithms incorporating these tests in community-based case management programs. A comprehensive synthesis of published literature on rapid diagnostic test sensitivity, specificity, operational challenges, and integration into community treatment protocols was conducted. Rapid diagnostic tests demonstrated high sensitivity (greater than 95%) for Plasmodium falciparum at parasite densities above 100 parasites per microliter, though performance declined substantially for non-falciparum species and low-density infections. Test performance is significantly affected by storage conditions, operator training, and product quality variation. Treatment algorithms incorporating rapid diagnostic tests have reduced inappropriate antimalarial use by 60 to 80% in community settings, improved targeting of artemisinin-based combination therapies, and enhanced detection of non-malarial febrile illnesses. However, adherence to negative test results remained inconsistent, with overtreatment rates of 10 to 40% reported across programs. Cost-effectiveness analyses demonstrated favorable outcomes when tests are combined with strengthened clinical algorithms and quality assurance systems. Rapid diagnostic tests represented valuable tools for community malaria case management when implemented within robust training, supervision, and quality control frameworks that address both technical and behavioral determinants of appropriate test use and treatment decisions.
