How is feline herpes virus diagnosed?
History and clinical signs can diagnose ocular diseases caused by feline herpes virus. Aside from history and clinical signs, diagnostic tests for feline herpes virus include virus isolation, immunofluorescent antibody testing, polymerase chain reaction testing, serology, and cytology. Testing can be expensive and is generally reserved for specific cases. Tests that may not specifically detect the presence of herpes may be used to detect ocular disease caused by herpes. These tests include a Schirmer tear test (measuring tear production), corneal staining, and conjunctival biopsy.
