VIDAS^® EQUINE ACTH and VIDAS^® EQUINE INSULIN offer published performance in terms of linearity and precision, with reliable results both for the initial diagnosis and for the long-term management of PPID and EMS.

PPID is a prevalent endocrine disorder marked by hormonal imbalances caused by age-related neurodegeneration in equines including horses, ponies and donkeys, regardless of breed or sex. The condition is diagnosed in 20%-30% of equines over 15 years old.² A progressive neurodegenerative disease, PPID compromises the function of the pituitary gland, progressively inhibiting the gland’s ability to regulate vital physiological processes deteriorates. Among the broad spectrum of clinical signs are a long, curly hair coat, delayed shedding, loss of muscle, poor immune function, and laminitis. ³

Adrenocorticotropic hormone (ACTH) testing is a key component in diagnosing PPID. When veterinarians suspect PPID based on clinical signs, measuring baseline ACTH levels provides confirmation. However, it’s important to consider context and timing for testing, as the test may miss early-stage disease⁴ and factors including natural seasonal fluctuations, stress or illness, may impact ACTH levels.

Insulin plays a crucial role in maintaining metabolic balance in horses. 18%-27% of horses suffer from insulin dysregulation, which can be associated with EMS (Equine Metabolic Syndrome).⁵ Certain subsets of horses including ponies, donkeys, Arabians and mustangs are particularly susceptible. Age is also a factor in insulin regulation.

Horses with EMS may experience abnormal fat deposits, inability to lose weight and infertility. Laminitis – less frequent but very challenging – is the most critical clinical sign associated with EMS.¹

Insulin testing is the cornerstone for diagnosing and managing EMS because glucose measurement is rarely useful, as horses usually exhibit compensated insulin resistance and do not develop diabetes. ^{6 , 7}
