Penny's story

Penny was diagnosed with Equine Cushing's disease and treated with a daily medication prescribed by her veterinary surgeon. The photos below show how Penny's topline, fat distribution and coat responded to this treatment over six months.

The simplest and most common test for Equine Cushing’s disease is the basal ACTH test.

To perform this test your vet will take a blood sample from your horse and send it to a laboratory that will measure the levels of a hormone called ACTH. The results of the test will then be compared to reference ranges (which change with the seasons) to confirm the presence or absence of Equine Cushing’s disease.

The measurement of serum insulin and glucose is often recommended alongside the basal ACTH test: These tests help to differentiate Equine Cushing’s disease from Equine Metabolic Syndrome (EMS) (another common hormonal cause of laminitis), and also act as an indicator of laminitis risk.

We are providing complimentary ACTH tests to horse owners who suspect their horse may have Equine Cushing’s disease.
