OBJECTIVE The aim of this study in pregnant women with hypothyroidism treated by levothyroxine is to examine the interrelations between thyroid-stimulating hormone (TSH), free thyroxine (FT(4)) and free tri-iodothyronine (FT(3)), and examine whether in such patients the treatment is adequate. METHODS This was a retrospective cross-sectional study. Maternal serum concentrations of FT(3), FT(4)...

PURPOSE To compare reduced colonic cleansing based on dietary fecal tagging (FT) with standard (non-FT) colonic cleansing with regard to patient acceptance, sensitivity, and specificity. MATERIALS AND METHODS In 50 patients (FT group), FT was performed by means of diet, magnesium citrate, and a barium suspension. In another 50 patients (non-FT group), preparation was based on polyethylene gly...

BACKGROUND The growing interest in measuring blood free testosterone (FT) is constrained by the unsuitability of the laborious reference methods for wider adoption in routine diagnostic laboratories. Various alternative derived testosterone measures have been proposed to estimate FT from either additional assay steps or calculations using total testosterone (TT) and sex hormone-binding globulin...
