Thyroid Panel
A comprehensive assessment of thyroid function including TSH, free thyroid hormones, and antibodies for autoimmune thyroid disease.
Purpose
The thyroid panel evaluates how well your thyroid gland is functioning. It measures the hormones that regulate metabolism, energy, and many body systems. It also checks for autoimmune thyroid conditions which are common, especially in women.
When to Order
Recommended when experiencing symptoms like fatigue, weight changes, temperature sensitivity, hair loss, or mood changes. Also used to monitor thyroid medication effectiveness and screen those with family history of thyroid disease.
Preparation Instructions
No fasting is required. If on thyroid medication, take it consistently relative to testing (usually test before taking morning dose). Biotin supplements should be stopped 2-3 days before testing as they can interfere with results.
