Thyroid Add-On Test Panel LabCorp (No TSH)

Thyroid hormones regulate our body's metabolism and influence virtually every organ system in the body. They tell organs how fast or slow they should work. Thyroid hormones also regulate the body's consumption of oxygen and production of heat. Thyroid problems, such as an overactive or underactive thyroid, can severely affect metabolism. There are several thyroid conditions you may want to be aware of. When the thyroid gland does not produce enough hormone, the body uses energy at a slower pace than it should. This condition, underactive thyroid, is called hypothyroidism. This panel includes Free T3, Free T4, Reverse T3, and Thyroid Peroxidase Antibody (Anti-TPO) and is typically ordered in conjunction with our Comprehensive Hormone and Wellness Panels.
