The Feline Infectious Peritonitis (FIP Antigen Rapid Test Device is a lateral flow immunochromatographic assay for the qualitative detection of FIP viral antigens in feline feces or ascites.
The FIP test device has a testing window containing a T (test) region and C (control) region. FIP antigens, if present in the sample will react with the pre-coated anti-FIP antibodies in the test strip. The mixture then migrates upward on the membrane chromatographically by capillary action and reacts with anti-FIP antibodies on the membrane in the test line region. A coloured line will appear in the test line region, indicating a positive result. If the sample does not contain FIP antigens, a coloured line will not appear in the test line region, indicating a negative result. To serve as a procedural control, a coloured line will always appear in the control line region indicating that the test has been performed correctly.
