Background: Malaria is still a global health problem that can cause death, especially in high-risk groups, namely infants, toddlers and pregnant women. One of the strategies in achieving malaria elimination is the early discovery of malaria cases quickly so that transmission can be stopped. The use of malaria Rapid Diagnostic Test (RDT) in areas with minimal trained human resources is still needed so it is necessary to evaluate the accuracy of the diagnostic results of the RDT examination. Aims: to determine the diagnostic value of the Rapid diagnostic test (RDT) including sensitivity, specificity, positive predictive value, negative predictive value, accuracy and relationship to microscopic examination in malaria suspects. Method: This study is an observational analytic study with a cross-sectional design. The data obtained came from all microscopic and RDT examination results at one public health centre (puskesmas) in Kokap Regency in the period January - December 2022 with a total of 93 samples. The analysis used was chi-square analysis along with sensitivity, specificity, negative predictive value, and positive predictive value tests. Results: from this study obtained a diagnostic test value of sensitivity 100% specificity 98.11%, positive predictive value 98%, negative predictive value 100% accuracy value of 99% and from Chi square non-parametric statistical test obtained p-value 0.000 which means there is a relationship between the results of Rapid diagnostic test and microscopic examination. Conclusion: Malaria RDTs have good diagnostic test results for malaria testing in malaria suspects.
