title: Determination of urinary estradiol using an enzymatic method during the menstrual cycle. Comparison with an method using isotope dilution-mass spectrometry (ID-MS).
abstract: Results for measurements of urinary estradiol were compared with results from a method using isotope dilution-mass fragmentography. Urine samples were collected from women during the menstrual cycle. The results obtained differed in absolute values, but showed good correlation.
