Comprehensive Thyroid At-Home Test

Individuals with thyroid dysfunction coupled with concerns about toxic element exposure and iodine/selenium deficiencies impact on T4 to T3 conversion.

Unlike a typical thyroid test (for just TSH), this at-home Blood Spot Test Kit will provide a complete Thyroid Profile including all of the components below. Simply follow the collection instructions inside the test kit, and drop the enclosed packaging in the mail as instructed. Your results will be sent to you or your healthcare provider.

Free T-3 (Triiodothyronine)

Free T-4 (Thyroxine)

Thyroid Stimulating Hormone (TSH)

Thyroid Peroxidase Antibodies (TPO)

The Thyroid Profile allows healthcare providers to screen for hypo or hyperthyroidism, test for autoimmune thyroid disease, and monitor thyroid replacement dosages.

Advantages of at-home thyroid blood spot testing:

Less expensive and more convenient than conventional blood draws

Nearly painless finger stick is used to collect the few drops of blood required

Private and convenient

Hormones and other analytes are stable in dried blood spot at room temperature for weeks.

Biomarkers For At-Home Comprehensive Thyroid Test Explained

TSH

Produced by the pituitary gland, TSH acts on the thyroid gland to stimulate production of the thyroid hormone thyroxine (T4).

Free T4 – Thyroxine

The predominant hormone produced by the thyroid gland, T4 is converted to its active form, T3, within cells.

Total T4 – Thyroxine

Total T4 includes both free T4 and protein-bound T4, and is an indicator of the thyroid gland’s ability to synthesize, process and release T4 into the bloodstream.

Free T3 – Triiodothyronine

T3 is the active thyroid hormone that regulates the metabolic activity of cells.

TPOab – Thyroid Peroxidase Antibodies

Thyroid peroxidase is an enzyme involved in thyroid hormone production. The body produces antibodies, including TPOab, that attack the thyroid gland in autoimmune thyroiditis and Hashimoto’s. Testing TPOab levels can diagnose these conditions.

Tgbn – Thyroglobulin

A protein rich in tyrosine, the residues of which when bound to iodine become the building blocks of T3 and T4. If iodine levels are low, thyroglobulin accumulates, thus high levels indicate insufficient iodine for healthy thyroid function.
