Thyroglobulin Test

Test Description

The thyroglobulin test is a blood test that measures the levels of thyroglobulin, a protein produced by the thyroid gland. This test is crucial in diagnosing and monitoring thyroid-related conditions, especially thyroid cancer. Thyroglobulin antibodies (TgAb) are also tested to detect autoimmune conditions involving the thyroid.

Indications of the Test

– **Diagnosing Autoimmune Conditions:** Thyroglobulin antibodies tests help diagnose autoimmune conditions involving the thyroid gland.
– **Monitoring Thyroid Disorders:** The test is used to diagnose and monitor thyroid disorders such as thyroiditis or goiter.
– **Thyroid Cancer Monitoring:** After thyroid cancer surgery, the thyroglobulin test is used to check for cancer recurrence by monitoring thyroglobulin levels.

Patient Preparation/Instructions

– **Fasting:** In most cases, fasting is not required for the thyroglobulin test.
– **Medication:** Patients may be advised to avoid certain medications like multivitamins and biotin before the test.
– **Procedure:** The test involves a simple blood draw, which is relatively painless and takes about 5 minutes.

Typical Reference Values

– **Normal Thyroglobulin Levels:** In healthy individuals without TgAb, the normal range is 3-40 ng/mL.
– **High Thyroglobulin Levels:** Levels above 40 ng/mL indicate high thyroglobulin levels, often associated with thyroid cancer recurrence.

Turnaround Time

The expected turnaround time for the comprehensive thyroglobulin test is 4-10 days. This test is used to monitor the recurrence of thyroid cancer and includes screening for antithyroglobulin antibodies.
