What is the positioning of the test spots on the SNAP Feline Triple Test?
• How should the SNAP Feline Triple Test results be interpreted? A heartworm antigen positive result is indicative of an adult heartworm infection. However, a negative test does not rule out feline heartworm infection. The recent discoveries associated with Heartworm Associated Respiratory Disease (H.A.R.D.) highlight an unfortunate drawback of antigen testing; antigen tests miss the early stage of feline heartworm disease associated with the immature adults. In cases where adult heartworm or H.A.R.D. are suspected, a negative antigen test should be followed up with an antibody test and may warrant additional tests such as radiographs and echocardiography as well as blood work. An FIV antibody positive result indicates that a cat has been infected with FIV and may have an active infection. An FeLV antigen positive result indicates that the cat is infected with FeLV.
