CD40LG and dengue disease: While 19/24 (79.2%) laboratories employed assays for both acute (RT–PCR) and recent (anti-DENV IgM) DENV infection, four performed antibody testing for dengue but lacked assays for early detection (pre-antibody immunological response) of dengue such as RT–PCR or NS1 kits and one could perform RT–PCR but had no serology capacity.
