[Determination of urinary estrogen in glycosuria].

The total urinary estrogen values of women with glucosuria were studied by 5 different methods in 287 samples. The spectrophotometry values obtained by Ittrich's reaction have been influenced by urinary glucose concentrations. An increased glucose content appeared to be connected with a decrease of the hormone values if the hydrolysis of conjugates was performed by mineral acids. The most effective method was enzymatic hydrolysis used also for the determination of the acid labile fractions. The determination of total estrogen excretion is necessary for evaluating intrauterine fetal well-being in diabetic mothers.
