In monitoring the treatment of malaria with Dihydroartemisinin-piperaquine (DHP), microscopic cross check and Polymerase Chain Reaction (PCR) performed to validate the results of laboratory examinations in the field. This study used finger prick samples from subjects with a diagnosis of malaria in monitoring the treatment of malaria with DHP in Kalimantan and Sulawesi. Samples taken at day 0, blood smears made on slides for microscopic and blood spot on filter paper for PCR examination. The PCR method used is a single-round multiplex polymerase chain reaction that has been modified, the examination of each species carried out in different tubes to distinguish the species P. falciparum or P. Vivax. Target of DNA amplification is a species-specific gene sequences in the small-subunit ribosomal RNA (SSUrRNA), 300 bp for P. falciparum and 276 bp for P.vivax. P. falciparum and P.vivax identified in 229 samples of blood smears and blood spots. Microscopic and PCR gave the same results, positive 93.4% and negative 6.6% with a sensitivity of 99% and specificity 93.3%. P.falciparum sensitivity and specificity of 92% and 99%, P.vivax 97% and 94%, PCR as a gold standard. There are differences in the results of examination of 5 samples, ie with microscopic examination identified as P.vivax while the PCR as P. falciparum. In this study, identification of the microscopic parasite similar to the results of identification by PCR, but differ in determining the types of parasites. In general, the ability to microscopic diagnosis of malaria is very good, but confirmation by PCR is still needed.
