After The Test & Treatment Options
After the Test
Once your specimen is submitted, results are typically processed and available within a few business days. However, processing times may vary. When ready, your results will be delivered in a clear, easy-to-understand report. If any results suggest a potential infection, you’ll receive a call from an independent healthcare coordinator. Independent physicians are also available to answer any questions or discuss your results in detail.

As part of your purchase, you have the opportunity to consult with an independent physician. If appropriate, they may be able to prescribe treatment based on your test results.
Age: 18+

Test Details & What It Measures
TSH (Thyroid Stimulating Hormone) test measures the level of TSH in your blood, which is produced by the pituitary gland to regulate thyroid function. TSH stimulates the thyroid gland to produce the thyroid hormones T3 (triiodothyronine) and T4 (thyroxine), which control metabolism, energy, and growth. This test is often used as the first step in evaluating thyroid health because TSH levels can provide important clues about whether your thyroid is overactive (hyperthyroidism) or underactive (hypothyroidism).
Normal TSH levels typically range from 0.4 to 4.0 mIU/L, although the exact range may vary depending on the laboratory and individual factors. High TSH levels often indicate an underactive thyroid (hypothyroidism), as the pituitary produces more TSH to try to stimulate the thyroid to produce more hormones. Conversely, low TSH levels are usually associated with hyperthyroidism, where the thyroid is overactive and producing too much hormone. Your healthcare provider will often order the TSH test alongside other thyroid tests, such as Free T4 and Free T3, to get a full picture of your thyroid health and help guide treatment decisions.
