Malaria is still one of problem of community health in Sumatera. Late diagnosis caused the high morbidity and mortality due to malaria. This study was carried out to compare RDT accuration in some groups of age in hypoendemic malaria. This diagnostic test study was conducted in Batubara Regency. The microscopy test was investigated by 3% Giemsa Staining and examined by trained laborant. RDT was carried out by using Monotes Test Drive, with 100% of sensitivity and 98,7% of specificity. Accuracy of RDT diagnostic was commonly significant in all groups of age, except in group of age > 65 years old (p=0.393). The highest sensitivity of RDT wass commonly in group of age ≤ 5 years old and decreased in the older group of age. Otherwise, the lowest specificity was found in group of age ≤ 5 years old and the highest in group of age 6-15 years old. The highest PPV and NPV was found in group of age 16-65 years old and ≤ 5 years old, respectively. The highest of parasite density was found in group of age≤ 5 years old (644.4 ± 494.5 parasit/µl) and the lowest in group of age > 65 years (400 ± 490.71 parasit/µl). The accuracy diagnosis of RDT reduce by increasing of age. RDT is still can be used as an alternative of malaria diagnostic test, especially in area that have not microscopy laborant.
