Clinical significance

Anti-thyroid microsome antibodies. TPO is the major antigen in microsomal fractions prepared from thyroid tissue. With concomitant evidence of thyroid dysfunction (abnormal test results or clinical symptoms), any increase in the level of anti-TPO antibodies is suggestive of autoimmune disease (Graves' or Hashimoto's disease). However, anti-TPO antibodies are also found in normal subjects.
