"The SUCCEEDŽ Equine Fecal Blood Test
The FBT is a non-invasive diagnostic aid that measures trace amounts of blood in the manure. Your vet simply collects fresh manure, mixes it with water and places a sample on two wells of the enclosed cassette. Within 15 minutes, this will tell if the horse has an excess of 2 blood components: albumin (a major component of the clear stuff we get with a scrape) and hemoglobin (the red stuff in blood.) Excess albumin indicates a hindgut lesion while excess hemoglobin indicates a bleeding lesion anywhere in the GI tract. Along with other indicators, these allow your veterinarian to pin-point the location of the problem(s)."
We tested 4 horses in our barn. 2 of the TB's (off the track) had severe. My guy was tested and had very mild. My barn mate had her Old Man Dutch Warmblood tested and he came up free and clear. It was pretty cool.
