Cat Feline Coronavirus PCR Diagnosis

PCR diagnosis of FCoV and FIP improves welfare outcomes by enabling earlier, more accurate diagnosis and appropriate treatment decisions.

Key Facts

PCR testing of effusions and tissues provides sensitive FIP diagnosis
Alpha-coronavirus RT-PCR can distinguish FCoV from FIP mutations in some cases
Protein electrophoresis of effusions helps diagnose wet FIP rapidly
GS-441524 and related antivirals require accurate diagnosis for appropriate use
Misdiagnosis risks either unnecessary treatment or delayed treatment of a treatable condition

Welfare Considerations

Accurate diagnosis is a welfare prerequisite for effective treatment. FIP misdiagnosis - in either direction - causes welfare harm through either unnecessary treatment costs or delayed antiviral treatment of a treatable condition. PCR and protein electrophoresis together improve diagnostic accuracy that translates into better treatment decisions and welfare outcomes.

What You Can Do

Seek specialist assessment including PCR testing for cats suspected of FIP
Discuss FIP antiviral treatment options following confirmed diagnosis
Support organisations improving access to FIP diagnostics and treatment
