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.
Treatment Options
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+
Must be 18+ to order blood tests.

Test Details & What It Measures
A TRAb (Thyroid Receptor Antibody) test measures the presence of antibodies that target the thyroid-stimulating hormone (TSH) receptor on the thyroid gland. These antibodies can disrupt normal thyroid function by either stimulating or blocking the receptor, leading to conditions of thyroid overactivity or underactivity. The most well-known association is with Graves’ disease, an autoimmune disorder in which the antibodies stimulate the TSH receptor, causing the thyroid to produce excess hormones.
This overproduction can lead to symptoms of hyperthyroidism, such as rapid heartbeat, weight loss, nervousness, and heat intolerance. A positive TRAb test is frequently used to confirm a diagnosis of Graves’ disease, especially when clinical signs of hyperthyroidism are present. However, elevated TRAb levels can occasionally be seen in other thyroid conditions or even in individuals without current symptoms.
The TRAb test is usually ordered in conjunction with other thyroid evaluations—such as TSH, Free T4, and Free T3—to provide a more complete picture of thyroid health and assist in treatment planning.
