As part of the USAID-led U.S. President’s Malaria Initiative, a PMI-S trained medical laboratory scientist conducts a malaria rapid diagnostic test for a malnourished child with a fever during the 2023 Therapeutic Efficacy Study on antimalaria in Nigeria. By conducting malaria rapid diagnostic tests, the medical laboratory scientist ensures that only patients with confirmed malaria receive antimalarial medication, reducing the unnecessary use of medication and mitigating the risk of resistance to antimalarial medications. This approach aligns with sustainable healthcare practices and helps preserve the efficacy of antimalarial treatments.
