The 'gold standard' for diagnostic confirmation is an '''agar gel immunodiffusion test (the Coggins test)''' which detects serum antibodies against the EIA virus. The test is 95% accurate for the diagnosis of EIA but false positives may be obtained from foals that have absorbed colostrum from affected mares and false negatives may occur during the acute stages of EIA. The Coggins test may be performed in combination with an '''[[ELISA]]''' or '''PCR''' test in order to increase the test sensitivity.

Additionally, haematology may reveal a moderate to marked anaemia, leukopaenia and bilirubinaemia. Mild thrombocytopaenia is common in the acute phase of infection.
