Diagnosis of FIV is made by demonstrating the presence of antibodies against the virus. ELISA tests are available for in-house use, with some kits detecting antibody to the core protein p24 and others detect antibody to the envelope protein gp4l<sup>2</sup>. Non-haemolysed plasma or serum is used for performing the in-house ELISA. Results must be interpreted with caution.
