Immunochromatographic Strip Assay

Method Description

Immunochromatographic strip assay for the qualitative detection of antibodies to the Leishmania donovani complex in serum (Kalazar Detect Rapid Test, InBios International). The test strip membrane is coated on the bottom with a band of recombinant K39 antigen and on the top with immobilized antiprotein A antibody to detect IgG. A protein A-gold conjugate is used as the detection reagent. For this test, 20 mcL of serum is added to the test strip. The appearance of both a control and test band is considered a positive result.(Carvalho SF, Lemos EM, Corey R, Dietze R: Performance of recombinant K39 antigen in the diagnosis of Brazilian visceral leishmaniasis.
