Thyroid Antibody Panel Blood Test

This panel assesses proteins involved in the production of thyroid hormones. It is possible for antibodies from your own immune system to attack these proteins, rendering them dysfunctional and resulting in fatigue, weight gain, constipation and other symptoms of low thyroid.

Description

This panel contains the following tests:

  • Thyroid antithyroglobulin antibody (ATA)
  • Thyroid peroxidase antibody (TPO)

Thyroglobulin and thyroid peroxidase are proteins involved in the production of thyroid hormones. It is possible for antibodies from your own immune system to attack these proteins rendering them dysfunctional. Both are often used in conjunction with each other to assess thyroid function, follow treatment for thyroid disease and differentiate between autoimmune conditions of the thyroid.

Antibodies to either of these important thyroid proteins can result in symptoms of low thyroid such as fatigue, weight gain, dry skin and constipation. Conditions such as Hashimoto’s thyroiditis, lupus, rheumatoid arthritis, and autoimmune hemolytic anemia often have these antibodies present.

Instructions

Fasting is not required for this test. Take all medications as prescribed.
