What Is Heartworm Testing?
Heartworm disease is very serious, but with early detection, your pet has a much greater chance of a full recovery. Regular testing is important because there are few, if any, signs of early heartworm infections. The test requires a small blood sample which allows us to detect the presence of any heartworm proteins, or antigens. An antigen test detects heartworm proteins which are released by adult female heartworms into a dog's bloodstream.
