Sensitivity of detecting P. falciparum LDH as a function of antibody gold conjugate. Test strips with immobilized 17E4 antibody specific for Pf-LDH were used to test for reaction to Pf-LDH. The dilution series (1:10) started with a pLDH solution diluted 1:100 from the stock solution to produce a sample solution estimated to represent a 10% parasitaemia. Tests were visualized with colloidal gold conjugated to the indicated antibodies.
