Three underdiagnosed diseases

Test for feline immunodeficiency virus (FIV), feline leukemia virus (FeLV), and heartworm disease
Feline immunodeficiency virus (antibody)

Screen all cats to detect specific antibodies to feline immunodeficiency virus (FIV) in feline serum, plasma, or anticoagulated whole blood. A positive test result indicates that an unvaccinated cat has circulating antibodies against FIV and, therefore, is likely infected.

Feline leukemia virus (antigen)

Screen all cats to detect feline leukemia virus (FeLV) antigen in feline serum, plasma, or anticoagulated whole blood. This rapid immunoassay detects the presence of FeLV p27 antigen, which, if found, is diagnostic for FeLV infection.

Feline heartworm disease (antigen)

Evaluate all cats for feline heartworm disease by identifying heartworm antigen in feline serum, plasma, or anticoagulated whole blood. Heartworm disease is caused by the filarial nematode Dirofilaria immitis, which has widespread dissemination. The insect vector for D. immitis is the mosquito. The detection of heartworm antigen is a definitive diagnosis for the adult stage of infection.
