Sensitivity and specificity from a study evaluating immunostaining for the detection of feline coronavirus (FCoV) antigen in aqueous humor samples. Feline infectious peritonitis (FIP) was confirmed by histopathology and immunohistochemistry (IHC) of tissue samples. The control group consisted of cats with diseases other than FIP with clinical signs (with or without uveitis) consistent with FIP.

Study	Number of Samples	Assay	Sensitivity	Specificity	Reference Standard for FIP	Control Cats
[132]	FIP (n = 26) Controls (n = 12)	ICC	64%	82%	Histopathology/IHC	Diseases other than FIP

ICC = immunocytochemistry.
