Analysis of diagnostic biomarkers for malaria: Prospects on rapid diagnostic test (RDT) development

Accurate malaria diagnosis remains a formidable challenge in remote regions of malaria-endemic areas globally. Existing diagnostic methods predominantly rely on microscopy and rapid diagnostic tests (RDTs). While RDTs offer advantages such as rapid results and reduced dependence on highly skilled technicians compared to microscopy, persistent challenges emphasize the critical need to identify novel diagnostic biomarkers to further enhance RDT based malaria diagnosis. This comprehensive review presents a range of promising diagnostic targets. These targets could be useful in developing more robust, accurate, and effective diagnostic tools. Such tools are crucial for the detection of the Plasmodium falciparum (P.falcipaum) malaria parasite. The potential biomarkers discussed here significantly address the challenges posed by HRP2 gene deletion in P.falciparum. Researchers, RDT manufacturers, industrial and other stakeholders involved in malaria diagnosis can harness the crucial information described in this article, to drive the development of advanced RDTs as viable alternatives. By diversifying the available tools for diagnosis, we can attempt to enhance our ability to knock out malaria effectively and contribute to better health outcomes for people residing in malaria-endemic regions. This review serves as a valuable resource for advancing research and development in the field of malaria diagnostics, ultimately aiding to the global fight against this devastating ancient disease.
