Thyroid Test Panel with TSH in California
Below is a plain-language overview of the thyroid test panel with tsh. This panel of tests evaluates how well your thyroid gland is working. It measures key hormones that indicate thyroid function.
What this test is
The Thyroid Test Panel with TSH assesses the health of your thyroid, a small gland in your neck that produces hormones regulating metabolism. This panel includes tests for Thyroid Stimulating Hormone (TSH), T3 uptake, T4, and T7.
What it measures
- TSH (Thyroid Stimulating Hormone) — reflects the pituitary gland's signal to the thyroid
- T3 Uptake — reflects the amount of thyroid hormone bound to proteins
- T4 (Thyroxine) — reflects the main thyroid hormone produced
- T7 (Free Thyroxine Index) — reflects the level of active thyroid hormone available to tissues
What the test involves
This test requires a blood sample, which is typically collected through a standard venipuncture procedure. A healthcare professional will draw blood from a vein in your arm.
Why it is often ordered
Clinicians often order this panel to check for thyroid disorders, such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid). It helps in diagnosing and monitoring conditions related to thyroid hormone levels.
