Clinical Context
Feline herpesvirus antigen or antibody testing supports diagnosis of FHV-associated respiratory or ocular disease and assessment of vaccine-induced immunity.
Interpretation should always combine the quantitative result with the patient's signalment, history, clinical signs, and any other laboratory findings. A single value is rarely diagnostic on its own; serial measurements often provide more useful information.
Reference Range
Reference ranges vary by species, age and laboratory method — always interpret against the kit IFU and your in-house validation.

FAQ
What does the Feline Herpesvirus (FHV) test measure?
Migibio's Feline Herpesvirus (FHV) test is a quantitative fluorescence immunoassay (FICT) run on the FIA680/FIA880 analyzer. It is intended as an aid in clinical assessment: Feline herpesvirus antigen or antibody testing supports diagnosis of FHV-associated respiratory or ocular disease and assessment of vaccine-induced immunity. The exact specimen, sample handling, and reporting units are specified in the kit IFU.
When is FHV testing most useful?
When a compatible clinical syndrome is present, during outbreak screening in kennels, catteries or shelters, or to assess vaccine-induced antibody titers after vaccination. Antigen and antibody tests answer different questions; interpret the result with vaccination history and clinical signs. For cats, use the result with the clinical history, physical examination, and any other laboratory findings.
