Abstract:
Sensitivity and specificity of the Asan Easy Malaria P.f/P.v tests (made by Asan Korean Company) in the diagnosis of P. falciparum and P.vivax malaria was investigated compared to Giemsa microscopy and re-checked by PCR technique. A total of 283 tests were conducted in the provinces of Lai Chau, Quang Binh and Binh Phuoc, and 90 other ones were carried out with cultured P. falciparum at the laboratories of the National Institute of Malariology, Parasitology and Entomology. The different results were found with two method as 111 positive cases were confirmed by Giemsa staining (59 P.falciparum and 54 P.vivax), while only 94 positive tests (53 P.falciparum and P.vivax) were determined by Asan. The samples with different results by two methods were re-cheked by PCR technique for confimation. The sensitivity and specificity of Asan tests in Plasmodium species detection were 97.8 and 89.9%, respectively, in general, and 99.0% and 91.2% in diagnosis of P falciparum, and 75.9% and 97% of P. vivax, in particular. However, in the following-up period (2-3 days), both methods showed the same results of parasite re-examination
