This test measures the unbound, biologically active form of thyroxine (T4) circulating in the blood. Unlike total T4, it reflects the portion not attached to proteins and available for use by tissues. Free T4 is a key marker of thyroid function and helps assess how much hormone is available to act on the body.

This test first measures TSH, the hormone that regulates thyroid function. If TSH is found to be outside the normal range, the lab automatically performs a follow up test to measure Free T4 - the unbound, active form of thyroxine. This reflex approach...

This test measures the level of TSH, a hormone produced by the pituitary gland that signals the thyroid to produce T3 and T4. It serves as the primary regulator of thyroid function and is commonly used to screen for thyroid imbalances.

This test measures the unbound, active form of triiodothyronine (T3) in the bloodstream. Free T3 is the most biologically active thyroid hormone and plays a central role in regulating metabolism, energy production, and cellular function.

This test measures the total amount of thyroxine (T4) in the blood, including both the protein-bound and free (active) forms. T4 is one of the primary hormones produced by the thyroid gland and plays a key role in regulating metabolism.

This test detects antibodies against thyroid peroxidase, an enzyme involved in thyroid hormone production. The presence of TPO antibodies may indicate an autoimmune response targeting the thyroid gland. Commonly used to assess for...

**Thyroid Panel (TSH, T3 Uptake, Total T4, Free T4 Index)** This panel assesses thyroid function and hormone transport dynamics using a combination of direct hormone levels and calculated indices. **TSH (Thyroid Stimulating Hormone)** A...

T3 Uptake is a test that measures the binding capacity of thyroid binding proteins in the blood. It provides indirect information about thyroid hormone levels, helping to evaluate thyroid function and diagnose thyroid disorders. This test aids...

### A Reverse T3 (rT3), Serum lab test measures the level of reverse triiodothyronine in the blood. Reverse T3 is an inactive form of the thyroid hormone triiodothyronine (T3) that is produced when the body converts thyroxine (T4) into rT3...
