Thyroid Hormone Testing

The thyroid gland is your body's regulator of energy. Low thyroid is very common in premenopausal and menopausal women. Symptoms of low thyroid can include fatigue, weight gain, foggy thinking, cold hands and feet, dry skin and brittle hair. These easy, accurate, virtually painless, take-at-home blood spot tests can give you a useful portrait of your thyroid function and save you the trip to a lab. You just follow the simple instructions, then mail the dry sample to the lab in a prepaid envelope.

NOTE: New York State Residents
New York State health law prohibits the testing of specimens collected in or mailed from New York, and prohibits the transmission of data from the laboratory to NY physicians or residents. Therefore, direct receipt of lab results for NY residents is not possible.

$260.00

This thyroid test kit is an overall assessment of thyroid function. Symptoms of thyroid deficiency can include weight gain, fatigue, dry skin, brittle hair and nails. Thyroid dysfunction can be a symptom of estrogen dominance and the risk of thyroid deficiency increases as we age. Test includes free thyroxine (fT4), free triiodothryronine (fT3), thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPO).

$69.00

Measures the amount of thyroid hormone manufactured by the thyroid gland. General indication of thyroid activity. If you're only ordering one test for thyroid function, this would be the one to choose. High levels of TSH indicate that the brain and thyroid gland are working hard to raise thyroid levels, thus it indicates low thyroid. Very low levels of TSH may indicate thyroid excess, but it's wise to test other thyroid parameters if this is the case.

$69.00

Blood Spot Test. Thyroxine is the main thyroid hormone produced by the thyroid. A well- regulated process causes thyroxine to generate the much more potent thyroid hormone T3 (Triiodothyronine).

$69.00

Blood Spot Test. Measures the level of active thyroid hormone T3. This level must remain within optimal range to keep the body functioning properly and is crucial for maintaining physical and mental health.
