Diagnosing PPID in horses is much more than a blood test. It’s a process.

In conversations with horse owners and trainers, look for information related to clinical signs associated with PPID (for example, changes in attitude, lethargy and delayed shedding) and when they were observed.

The goal of physical examinations is to identify and confirm the horse is displaying clinical signs consistent with PPID and determine whether they are early or advanced.

If a horse has a medical history and clinical signs consistent with PPID, at a minimum ACTH, insulin and glucose should be evaluated.
- Only new cases suspected of PPID (not previously diagnosed)
- Patient should exhibit one or more early or advanced clinical signs of PPID
- Patients currently being administered medical therapy for PPID are excluded, except horses being administered compounded pergolide
