Aims To assess potential assay interference as the cause of aberrant thyroid-stimulating
hormone (TSH) and free thyroxine (FT4) results. Methods It is well documented that …

Automated immunoassays used to evaluate thyroid function are vulnerable to different types
of interference that can affect clinical decisions. This review provides a detailed overview of …

Introduction Interference due to the presence of heterophilic antibodies may lead to falsely
low or high analyte concentrations, but falsely elevated values are more common in most …

Thyroid function tests are prone to analytical interference, which can cause misleading
results when performed on automated immunoassay analyzers. We present a case of a 68 …

Automated immunoassays are extensively used in routine laboratory diagnostics of
endocrine disorders because of their advantages, such as high sensitivity, precision, and …

Background: Endogenous and exogenous factors may cause biochemical interferences with
thyroid function immunoassays. Interference can be caused by many mechanisms including …

Immunoassays are now commonly used for hormone measurement, in high throughput
analytical platforms. Immunoassays are generally robust to interference. However …

Interference, for instance due to the presence of heterophilic antibodies, is a well-known
pitfall in diagnostic immunoassays. Although these antibodies were reported to be present in …

Measurements of thyrotropin and of total and free thyroxine and triiodothyronine are widely
used diagnostic methods for thyroid function evaluation. However, some serum samples will …

Background Anti-streptavidin antibodies are causal determinants of analytical interference
during Thyroid function tests, and numerous reports have detailed such interference, with …
