An ELISA test used to diagnose heartworm infection in dogs detects which type of target?

Explanation:
An ELISA used to diagnose heartworm infection targets a parasitic antigen. Specifically, it detects circulating antigen produced by the heartworm (Dirofilaria immitis) in the dog’s blood, usually from adult female worms. This is different from tests aimed at bacteria, viruses, or fungi. The assay uses antibodies that bind the parasite antigen and produce a measurable signal. Keep in mind that very light infections or infections with only male worms can yield false negatives because the circulating antigen may be too low to detect.
