This package includes TSH, Free T3 and Free T4, 3 common tests for measuring Thyroid Function. The thyroid is a small butterfly shaped gland which produces hormones that regulate a number of vital bodily functions. The thyroid controls your metabolism, heart rate, body temperature, digestive system, muscular system and cell production. The two main hormones produced by the thyroid are Thyroxine (T4) and Triiodothryonine (T3). Hormone production is determined by the level of Thyroid Stimulating Hormone (TSH) which is produced by the pituitary gland.
Free T3 and Free T4 are the portions of the hormones which are not bound to proteins and thus available for the body to use. Measuring the unbound levels of T3 and T4 can be more accurate for some people than measuring Total T3 and T4.
Customers who are looking for a more comprehensive thyroid testing package which includes additional measurements may wish to order the Thyroid Comprehensive Panel with Free or the Thyroid Comprehensive Panel with Reverse and Free.
