ABSTRACT
Objective To evaluate the effect of BinaxNOW rapid diagnostic devices for malaria in the field. Methods The symptomatic patients were detected by using the BinaxNOW devices and the results were compared with the microscopic examination of Giemsa-stained blood smears(as a golden standard). The sensitivity and specificity were calculated. The double-blind method was used in this study. Results In 443 symptomatic patients,151 cases were positive for malaria. The sensitivity was 98.69% and the specificity was 100%,and the coincidence rate of BinaxNOW with the microscopic examination was 99.55%. The sensitivity and specificity of Plasmodium falciparum were 100% and 99.66%,respectively,and the coincidence rate was 99.76%. The sensitivity and specificity of non-falciparum Plasmodium were 90.91% and 100%,respectively,and the coincidence rate was 99.36%. Conclusion The BinaxNOW rapid diagnostic devices for malaria are sensitive,specific,and stable for malaria diagnosis in the field.
