The Canine TSH Enzyme Immunoassay is a specialized diagnostic test designed to quantitatively measure thyroid stimulating hormone (TSH) levels in dogs to support the evaluation of thyroid function. Abnormal TSH concentrations, particularly elevated levels, may indicate conditions such as hypothyroidism, one of the most common endocrine disorders in canines. The assay is performed using serum samples and includes calibrators formulated with canine serum matrices to help ensure accurate and reliable results. This test aids veterinarians in the diagnosis, monitoring, and management of thyroid-related disorders in dogs.
