filarial antigen detection test

A filarial antigen detection test is a blood test used to identify ongoing infection with filarial worms, which cause diseases like lymphatic filariasis. The test detects specific substances, called antigens, released by the adult worms into the bloodstream. If these antigens are present, it indicates an active infection. This test is useful because it can identify infection even when no symptoms are visible and helps guide treatment decisions. It is a sensitive and reliable method for screening and monitoring the presence of the worms in affected individuals.
