Interference in thyroid-function tests in postpartum thyroiditis.
Three women are described from a study of patients with postpartum thyroiditis whose sera gave spuriously increased concentrations of free thyroid hormone because of antibody binding of radiolabeled thyroxin (T4) and triiodothyronine (T3) analogs. All of the women showed increased serum concentrations of thyroid autoantibodies. The antibody binding of radiolabeled analogs and its effect on free...
متن کاملOdd thyroid function tests results: interference versus non-compliance
Despite the advent modern immunoassays, particularly with regards to TSH measurements, clinicians still encounter seemingly inexplicable results of thyroid function tests, for instance raised concentrations of free hormones (free T4 and/or free T3) in the setting of high, or at least not suppressed TSH concentrations.

متن کاملInterference in laboratory tests
Interference in clinical laboratory testing can create discrepancies in test results which can lead to patient harm. In clinical chemistry, interference is defined as a cause of medically significant difference in the measurand test result due to another component or property of the sample.
