Abstract
Rapid, simple, accurate and cheap methods are required for the diagnosis of malaria in endemic areas. The ParaSight(R)-F test, which is based on qualitative detection by monoclonal antibody of the Plasmodium falciparum (Pf) histidin-rich protein-II in the blood, showed promising results. As some antigens of Pf have been detected in the urine, we assessed the efficiency of the ParaSight(R)-F test in the whole blood and in the urine using microscopy and PCR as gold standards. One hundred and twelve children living in the East Sepik Province of Papua New Guinea (PNG) were recruited during a cross-sectional community survey. When using microscopy as reference, the ParaSight(R)-F test applied to whole blood had 84% sensitivity and 77% specificity. The semi-quantitative assessment showed that the intensity of the color on the wick correlated with parasite density. The ParaSight(R)-F test performed on urine had 81% sensitivity but only 26% specificity. Very similar results for blood and urine were obtained when using PCR as reference. The present evaluation of the ParaSight(R)-F test applied to blood compares well with findings in endemic areas of Africa or Asia, and confirms its usefulness to diagnose Pf infection in endemic areas of the South Pacific. Because of the lack of specificity, the ParaSight(R)-F test performed on urine cannot be recommended.
