General Information
New 2026 Laboratory Test Prices, Effective May 1, 2026.
The Diagnostic Endocrinology Service at the University of Tennessee, College of Veterinary Medicine provides adrenal, thyroid, and reproductive hormone testing for dogs and cats, as well as for several other species. Our Service has gained a national and international reputation for providing adrenal steroid profile testing. The adrenal steroid profiles (also known as adrenal panels) are determined in dogs, cats, ferrets, and rabbits that are suspected of having adrenal disease. These profiles provide a more complete evaluation of adrenocortical function by assessing hormone concentrations that arise from different parts of the hormone synthesis pathway. Classically, most adrenal function tests in animals involve the measurement of only cortisol however in some individuals these tests give normal cortisol results even though the animal has clinical signs suggestive of hyperadrenocorticism.
Our Diagnostic Endocrinology Service is the only veterinary diagnostic laboratory in the United States to offer an adrenal steroid profile test in dogs, cats and rabbits and was the first to offer this test in ferrets.
Diagnosis of hyperadrenocorticism–mission not impossible
