Currently, useful and reliable markers for EGUS are lacking.<ref name="EGUC">The Equine Gastric Ulcer Council (1999) Tutorial Article: Recommendations for the diagnosis and treatment of equine gastric ulcer syndrome (EGUS). ''Equine Vet Educ'', 11(5):262-272.</ref> The SUCCEED Equine Faecal Blood Test uses specific equine monoclonal antibodies to albumin and haemoglobin to detect occult blood in faeces.(Carter and Pellegrini 2006; Pellegrini and Carter 2007) The test has a positive predictive value of 77% and a negative predictive value of 72% and thus cannot be relied upon alone to diagnose EGUS(Nadeau 2009). False positive results may arise from rectal trauma (e.g. recent biopsy or rectal examination) or protein losing enteropathy.(Nadeau 2009)
