Wedgewood Pharmacy is now able to make TRH (protirelin) to perform TRH stim testing to aid in the diagnosis of equine Cushing's disease. Keep in mind that we do not recommend utilizing a TRH stim test between the months of August - October. We expect seasonal elevations in ACTH levels during this time period that can result in false positive TRH stim test results. If you have questions on the fall seasonal rise, how to use this test, or test result interpretation, please call the office at 607-253-3673.
