Fecal Alpha Protease Inhibitor (API) Test:
Screening for Protein-Losing Enteropathy (PLE)

Recommended but OPTIONAL

Early diagnosis of Protein-Losing Enteropathy (PLE) in the Soft Coated Wheaten Terrier (SCWT) is challenging. Many cases show no clinical signs. The Alpha Protease Inhibitor (API) test has proven to be a valuable screening tool for intestinal protein loss in Wheatens even before other clinical signs develop. It is recommended that you screen your Wheaten annually for PLE. If any of the results are consistent with protein-loss, semi-annual screening is recommended to further monitor for PLE.

NOTE: The Gastrointestinal Lab at Texas A&M will only accept kits obtained through SCWTCA or from Vets who order tubes directly from the GI Lab. They will not accept makeshift containers from owners that may contain improper tubes, paperwork, etc. Results of your dog's Fecal API will be sent to your veterinarian
