This test helps detect possible thyroid problems. Antithyroglobulin antibodies can be a sign of thyroid gland damage caused by the immune system. They may be measured if thyroiditis is suspected. Measuring thyroglobulin antibody levels after treatment for thyroid cancer can help your provider decide what the best test is to monitor you for a recurrence of the cancer.
In this test antibodies to thyroglobulin are detecte in the blood of the patient. Normal Results
A negative test result is a normal result. It means no antibodies to thyroglobulin are found in your blood.
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results.
What Abnormal Results Mean
A positive test means antithyroglobulin antibodies are found in your blood. They may be present with:
Graves disease or overactive thyroid
Systemic lupus erythematosus
Type 1 diabetes
Pregnant women and relatives of those with autoimmune thyroiditis may also test positive for these antibodies.
Blood tests are normally well-tolerated. Some people have smaller or larger veins, which may make taking a blood sample more difficult. However, risks associated with blood tests like the ACTH hormone test are rare. Uncommon risks of having blood drawn include: excessive bleeding lightheadedness or fainting hematoma, or blood pooling under the skin infection at the site
Patients frequently become ill with fever and prefer to be in bed.
Thyroid antibodies are not present in the blood, but the sedimentation rate (which measures inflammation) is very high.
Although this type of thyroiditis resembles an infection within the thyroid gland, no infectious agent has ever been identified, and antibiotics are of no use.
Treatment is usually bed rest and aspirin to reduce inflammation.
Occasionally cortisone (steroids, which reduce inflammation) and thyroid hormone (to "rest" the thyroid gland) may be used in prolonged cases.
Nearly all patients recover, and the thyroid gland returns to normal after several weeks or months.
A few patients will become hypothyroid once the inflammation settles down and therefore will need to stay on thyroid hormone replacement indefinitely.
Test Method 1 : The thyroglobulin antibody test is a blood test. A nurse or technician will draw your blood from a vein near your elbow or hand. This blood will be collected in a tube and sent to a lab for analysis. There the activity of thyroglobulin antibodies in patient is measured.
Your doctor will contact you to explain your results when they become available.
Report available : The turn around time for this test is around 24 hours.
