What is the purpose of this test?
The Thyroglobulin Panel Blood Test is designed to measure levels of thyroglobulin and thyroglobulin antibodies in your blood. Thyroglobulin is a protein produced by the thyroid gland, which plays an essential role in the production of thyroid hormones that regulate metabolism, energy levels, and other vital functions in the body. Elevated levels of thyroglobulin in the blood may indicate issues with thyroid health, such as inflammation, nodules, or other thyroid-related conditions.
Additionally, this test checks for thyroglobulin antibodies, which are immune system proteins that attack thyroglobulin. High levels of thyroglobulin antibodies may suggest an autoimmune response, often associated with thyroid diseases like Hashimoto's thyroiditis or Graves' disease. Monitoring thyroglobulin and thyroglobulin antibodies is particularly valuable for people with a history of thyroid cancer, as it helps healthcare providers detect any recurrence or persistence of thyroid cells.
The Thyroglobulin Panel Blood Test includes:
- Thyroglobulin: Measures the level of thyroglobulin protein in the blood, which helps assess thyroid health and monitor for thyroid cancer recurrence.
- Thyroglobulin Antibodies: Detects antibodies against thyroglobulin, indicating potential autoimmune thyroid conditions that could impact thyroid function.
Who should get this test?
- Individuals with a history of thyroid cancer
- Patients undergoing treatment or follow-up for thyroid cancer
- People with symptoms of thyroid disease, such as fatigue, weight changes, or hair loss
- Those diagnosed with autoimmune thyroid disorders like Hashimoto's or Graves' disease
- Individuals with a family history of thyroid disorders
Benefits of the Thyroglobulin Panel Blood Test:
- Thyroid Cancer Monitoring: Assists in tracking thyroid cancer treatment progress and detecting any recurrence.
- Autoimmune Detection: Identifies antibodies that suggest autoimmune thyroid conditions, like Hashimoto's or Graves' disease.
- Thyroid Health Management: Provides valuable insights for healthcare providers to manage thyroid-related health issues effectively.
- Early Intervention: Enables timely detection of abnormal thyroid activity or immune response, supporting proactive care.

Preparation:No fasting is required. Patients should stop taking biotin at least 72 hours before giving a sample for this test as biotin supplements may interfere with results.
Test Results:
1-6 days. May take longer based on weather, holiday, or lab delays.
Details:LabCorp Only:
For all LabCorp Thyroglobulin Panel Blood Test samples, TgAb is tested first.
- If TgAb is negative, thyroglobulin levels are measured using a highly sensitive, quick method, with results typically available within 2-3 days.
- If TgAb is positive, a specialized testing method is used to prevent interference from antibodies, ensuring more accurate results. This method may take 4-6 days to complete.
This process helps ensure the most accurate thyroid health results.
