Each laboratory should establish trimester-specific reference ranges for pregnant women if using a free T4 assay," the authors wrote in a supplemental index in which they summarized changes between the 2007 and 2012 versions of the guideline.
The standard blood tests for thyroid problems are TSH (thyroid stimulating hormone), estimates of free T4 (thyroxine or tetraiodothyronine), total and estimates of free T3 (triiodothyronine), and thyroid antibodies; others are usually not necessary," says Dr.
In addition, we ran the subsequent patient's sample for thyroid stimulating hormone and free T4 on the E170 and the Advia Centaur analyser in our laboratory.
This unique combination of a critically high TSH and a normal free T4 concentration, however, made a mislabeled sample unlikely.
With one exception- all the women in the study with low TSH levels had normal free T4 levels, which corresponds to the definition of subclinical hyperthyroidism.
Williams and his colleagues reported that higher levels of free thyroxine (T4) and triiodothyronine (T3) were associated with significantly lower BMD at the hip, and higher free T4 was associated with increasing bone loss at the hip.
