When T4 levels alone do not provide a clear diagnosis, TSH testing offers critical insight. These TSH Test Kits are ideal for the diagnosis, treatment planning, and ongoing monitoring of hypothyroidism. Designed for veterinary clinical use, they deliver accurate and reliable results to support confident medical decisions. An essential tool for managing thyroid health, especially when combined with T4 testing for a comprehensive evaluation.
