Harmonization and standardization of thyroid function tests.
This issue of Clinical Chemistry contains 3 reports from the IFCC Working Group for Standardization of Thyroid Function Tests. The first report relates to thyroidstimulating hormone (TSH) (1 ), the second addresses free thyroxine (FT4) and free triiodothyronine (FT3) (2 ), and the third discusses total thyroxine (T4) and total triiodothyronine (T3) (3 ). Each of these reports is authored by a g...

متن کاملInterpretation of thyroid function tests.
The introduction of sensitive thyrotropin assays and free thyroid hormone measurements has simplified the interpretation of thyroid function tests. However, important pitfalls and difficult cases still exist. In this review, thyroid function test results are grouped into six different patterns. We propose that if assays for thyrotropin, free T3, and free T4 are all done, knowledge of these patt...
