Total testosterone concentration fell progressively during the menstrual cycle,...
In 13 patients with primary hypogonadism total T concentration was similar to that of Turner patients (13.12±5.4 ng/100 ml) so as was the percentage of T bound to proteins and unbound T levels. The physiological implications of free and bound testosterone concentrations in newborns, prepuberal ...
We compared the clinical value of information on free testosterone as measured with the Coat-A-Count (Diagnostic Products Corp.) radioimmunoassay kit involving a ligand analog with that of total testosterone, the free-androgen index, and free testosterone calculated from concentrations of testosterone,...
