Thyroid Test Panel with TSH in South Dakota

A thyroid test panel with TSH checks how well your thyroid gland is working. It is often ordered when you have symptoms like fatigue, weight changes, or a lump in the neck, or to monitor thyroid treatment.

What it measures

TSH (thyroid-stimulating hormone) — A hormone from the pituitary gland that tells the thyroid to work. High TSH often means an underactive thyroid; low TSH may mean an overactive one.
Free T4 (thyroxine) — The main thyroid hormone in your blood. It helps control energy and metabolism.
Free T3 (triiodothyronine) — The active form of thyroid hormone. It affects how your body uses energy.
Thyroid peroxidase antibodies (TPO Ab) — Antibodies that can attack the thyroid. Their presence may suggest an autoimmune thyroid condition.

Who it is for

A doctor or other clinician typically orders this panel if you have symptoms of a thyroid problem, an abnormal finding on an exam, or if you are already taking thyroid medication and need monitoring.

Preparation

No fasting is usually required. Tell your clinician about any medicines or supplements you take, because some can affect thyroid test results.

Results and what they mean

Results are reported as numbers with reference ranges. Your clinician interprets them along with your symptoms and history. This is general information, not medical advice; only a qualified professional can diagnose or treat a thyroid condition.
