Applying SUCCEED® Equine Fecal Blood Test Results

There’s more to understanding the results of the SUCCEED Equine Fecal Blood Test than recognizing positive or negative results. While the SUCCEED FBT results are not difficult to interpret, understanding how they fit into the big picture of a complete and accurate diagnosis requires the specialized knowledge of a trained and certified veterinarian.

How to Interpret Positive and Negative FBT Results

The following chart summarizes the meaning of a positive and/or negative test results across SUCCEED FBT tests A and H.

FBT Results Chart
  • Negative A, Negative H = no GI tract issue detected.
  • Positive A, Negative H = GI tract issue detected in hindgut.
  • Negative A, Positive H = GI tract issue detected in foregut.
  • Positive A, Positive H = GI tract issue in hindgut. Foregut issue also possible.

Make a More Accurate Diagnosis Using FBT and S.O.A.P.

The results of the SUCCEED Equine Fecal Blood Test are just one factor to consider when a veterinarian is diagnosing a potential GI tract injury in a horse. Here are examples of factors to keep in mind throughout the diagnostic process, in addition to FBT results.

Subjective Information

How do the horse’s symptoms and history point to a particular GI pathology, or set of pathologies?

Does the horse display any of these symptoms?

  • poor hair coat, weight loss, or inappetance
  • diarrhea or intermittent loose stools
  • resistance, lethargy, or poor behavior under saddle
  • girthiness, cribbing, or other stall vices
  • difficulty bending, collecting, or moving forward

Does the horse’s current or past management include any of the following?

  • feeding concentrates
  • restricted turnout
  • large meals
  • hours between meals
  • traveling
  • competing
  • riding regularly

All of these are potential signs of, or risk factors for, poor gut health.

Objective Data

The SUCCEED FBT is just part of an arsenal of objective diagnostic tools that can aid in evaluating potential GI conditions. Others include:

  • endoscopy
  • fecal pH levels
  • blood CBC

Information provided using these and other objective methods can help to narrow the diagnosis after a positive FBT result. Note that the FBT should not be used as a replacement for endoscopy, as it cannot detect grade 1 ulcers in a horse’s stomach. Additionally, while a positive for both albumin and hemoglobin indicates a definite hindgut issue, an accompanying gastric condition may also be present.

Assessment

All of the information gathered subjectively and objectively along with a positive FBT result can help narrow down potential diagnoses. Armed with this information, veterinarians can more accurately identify GI conditions such as:

  • gastric ulceration
  • colonic ulceration
  • enteritis
  • protein losing enteropathy (PLE)
  • parasitism

The FBT may also be used to monitor wellness as well as recovery after GI surgery.

Plan

A more accurate diagnosis allows for a more targeted, effective treatment. Here, the differentiation that the FBT helps provide becomes critical, as management of the foregut versus the hindgut differs widely.
