Clinical Utility:
A positive bias has been observed for the current Thyroglobulin reagent. A nation-wide shortage has made it impossible to order replacements for our current reagents. Therefore, effective April 17, 2012 PathGroup will switch testing to an alternate platform which will result in a change to expected values and the Reference Range for Thyroglobulin Antibodies. Thyroglobulin autoantibodies (TgAb) are often present in patients with autoimmune thyroid disease. This assay is intended to be used as an aid in the diagnosis of Hashimoto’s and Graves’ diseases which are autoimmune diseases affecting the thyroid gland. This assay is also necessary to identify patients whose serum contains Thyroglobulin autoantibodies that may interfere with serum Thyroglobulin measurements.
