The SUCCEED® FBT is an accurate and sensitive test for excessive equine occult blood in the manure. Ulceration is defined by Dorland’s Illustrated Medical Dictionary as “a local defect, or excavation, of the surface of an organ or tissue, which is produced by the sloughing of inflammatory necrotic tissue.”

Keep in mind that occult fecal blood can arise from a variety of GI tract conditions, including but not limited to:

• Bleeding ulcers (gastric or colonic)
• Excessive parasite activity
• Protein-losing enteropathy (PLE)
• Lesions caused by hard particles of feed or other ingested material
• Petechiation, hyperemias or lypomas

Additionally, a positive test result (especially Test H) can arise from extraneous sources, such as:

• After dentistry or exercise-induced pulmonary hemorrhage
• Mare ovulation
• Post-surgery bleeding

As with any diagnostic, a definitive diagnosis should not be based on the result of a single test. The test is designed to be complementary to blood tests and physical examination. For practitioners experiencing a positive Test A without a positive Test H, one of the differential diagnoses should include a protein-losing enteropathy, especially in the presence of hypoproteinemia/hypoalbuminemia on a CBC/chem profile.
