title: Heterophile antibody interference with thyroid assay.
abstract: Immunoassays are one of the main methods of measuring thyroid hormones. They are prone to interference. Interference of the immunoassays has been increasingly recognized as a problem because it may lead to misinterpretation of results resulting in unnecessary investigation and wrong course of treatment. We describe a patient who had interference in her thyroid function measurements (free T4, free T3 and TSH) during the course of treatment for Graves' disease.
