Thyroid Hormone Testing

FEATURING ZRT LABORATORY TESTING!

Reliable, Accurate, Easy-to-Use!

TEST WITH THE BEST

The thyroid gland is your body's regulator of energy. Low thyroid is very common in premenopausal and menopausal women, and in older men. Symptoms of low thyroid can include fatigue, weight gain, brain fog, cold hands and feet, dry skin and brittle hair and nails.

The blood spot sample is collected at home with a simple finger-stick, and then sent to the lab in a convenient prepaid mailer. Once the sample reaches the lab, results are typically ready in 3 to 5 business days. Results reports can be accessed online or sent via snail mail.

The ZRT Thyroid tests are an accurate and reliable way to assess thyroid function. 

NY State residents:
New York State health law prohibits the testing of blood spot specimens collected in or mailed from New York and prohibits the transmission of blood spot laboratory data NY physicians or residents. New York residents may order saliva tests.

Blood spot test. Results and written recommendations and analysis included. 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.
