Hypothyroidism is the most common endocrine disorder of dogs. Nearly 90% of cases result from autoimmune thyroiditis, the heritable autoimmune disease that progressively destroys the thyroid gland. Classical clinical signs of hypothyroidism only appear once >70% of the gland is damaged.

Hyperthyroidism is the second most common endocrine disorder of middle aged and older cats, after diabetes.   These cats often have concurrent kidney disease, making it difficult to identify the hyperthyroidism without a more complete thyroid profile. Measuring T4 alone can be misleading as this hormone  can be suppressed into the upper end of the normal reference range by any non-thyroidal illness.

Non-RIA Technology
Hemolife uses the most comprehensive, patented, and environmentally green non-RIA technology that has never been offered before in veterinary medicine. Hemolife's technology is covered by multiple US and international patents. Additionally, this technology is supported and enhanced by breed and age-specific interpretation.

Thyroid Profile 5™ - The Most Comprehensive Canine Thyroid Test Available on the Market
The Thyroid Antibody Panel, Thyroid Profile 5, includes T4, freeT4, T3, freeT3 and TGAA. Since there is an 8% chance of having a false negative TGAA, Hemolife will perform either the T3AA or T4AA when results warrant it or in cases where T3AA or T4AA were previously done and needed for a follow-up. Each sample includes a personal interpretation from Dr. Dodds or one of our other expert veterinarians plus consultation and follow up questions if desired.

T4:FT4 Ratio (Dogs only)
The patented T4:FT4 Ratio has been added to Hemolife's portfolio of all “green” technology and breed- and age-specific interpretive analysis, and is available on all of Hemolife's thyroid profile laboratory results to assist veterinarians in diagnosing thyroid conditions more accurately.

Thyroid GOLD Registration & Certificate
Hemolife Diagnostics Laboratory offers the Thyroid GOLD™ Registration & Certificate that can be ordered with any of the Hemolife Thyroid Profile 5 tests. The OFA Registry only measures free T4 ED, TSH and TGAA, whereas Hemolife's Thyroid Profile 5 is more comprehensive by measuring T4, FT4, T3, FT3 and TGAA. This certificate adds an extra level of assurance to breeders that dogs do not have autoimmune thyroiditis.
