[Interpretation of a health industry standard Detection of Plasmodium spp. Immune-chromatographic test (WS/T...

Malaria remains one of the most serious public health problems worldwide. After China achieved the target for malaria elimination, thousands of imported malaria cases are still reported annually. Timely and accurate diagnosis is critical to clinical treatment of cases and prevention of re-establishment of imported malaria. Detection of Plasmodium antigens is one of the criteria for definitive diagnosis of malaria. Malaria rapid diagnostic tests (RDTs) based on the immunochromatographic assay have become an important tool for clinical diagnosis of malaria due to convenient procedures and rapid detection. Nevertheless, there are still multiple misunderstandings pertaining to use of malaria RDTs among workers in medical and disease control and prevention institutions at all levels across China. To standardize technical guidelines and operational procedures for detection of Plasmodium spp., the National Disease Control and Prevention Administration has arranged the formulation of a recommended health industry standard Detection of Plasmodium spp. Immune-chromatographic test (WS/T 10029-2025), which has been officially iming immunochromatographic assays, including the testing principles, sample collection and detection procedures, and result interpretation, which provides the technical basis and operational specifications for detection of Plasmodium antigens in medical and disease control and prevention institutions at all levels. Based on analysis of the epidemiological characteristics of imported malaria in China, this article interprets the core content of this standard, aiming to promote its dissemination, implementation, and practical applications.
