Dried blood spot (DBS) tests for thyroid hormones and antibodies, especially for markers like TSH, FT3, FT4, TPOab, Tgbn, and TT4, have demonstrated high correlation with traditional venipuncture methods. Our CLIA-certified lab analysis ensures reliable and accurate results, offering a convenient way to check thyroid levels at home with confidence.

Many individuals already taking thyroid medication find this comprehensive at-home thyroid panel valuable for monitoring their levels and assessing the effectiveness of their treatment. This TSH FT3 FT4 TPOab Tgbn TT4 test can help identify imbalances and provide data for discussions with your doctor about dosage adjustments or further investigation into symptoms of thyroid imbalance.

TSH (Thyroid Stimulating Hormone) regulates thyroid hormone production. FT3 (Free Triiodothyronine) and FT4 (Free Thyroxine) are the active thyroid hormones. TPOab (Thyroid Peroxidase Antibodies) and Tgbn (Thyroglobulin Antibodies) indicate autoimmune activity, often associated with Hashimoto's thyroiditis. TT4 (Total Thyroxine) measures the total amount of T4. Together, these markers provide a comprehensive thyroid lab test, crucial for understanding your thyroid function and screening for thyroid disease.

A small amount of blood is collected from a fingertip using a lancet and placed onto a provided dried blood spot card. Detailed, step-by-step instructions are included with your kit. It's crucial to follow these carefully to ensure a good sample. If you believe your sample was improperly collected, please contact our support team for guidance on potential re-testing options.
