[Direct assay for urine cortisol with cortisol kit [TFB]].
We examined Cortisol Kit [TFB] for direct assay of urine cortisol. And the multiplication by dilution factor of urine cortisol values in this kit was examined. The coefficient of correlation of cortisol levels (46 urine samples) between Cortisol Kit [TFB] and Chemilumi ACS-Cortisol II, which is another kit for direct assay of urine cortisol, was r = 0.858, y = 1.86x + 38.2 (p < 0.001). There we...
متن کاملFree cortisol and creatinine in urine of healthy children.
Cortisol and creatinine were measured in two consecutive overnight urine collections from 103 healthy school children, ages seven to 18.5 years. Mean cortisol and creatinine concentrations were respectively 194 nmol/L and 12.7 mmol/L. The data were statistically analyzed to simultaneously assess any effects of sex, age, weight, day of collection, and urine volume. Mean urine volume for boys exc...

متن کاملAn enzyme-linked immunosorbent assay (ELISA) for urinary free cortisol.
Since the introduction of our plasma cortisol enzyme-linked immunosorbent assay (ELISA) [l] using affinity purified antiserum [2] into the routine steroid laboratory, we have embarked on the development of a simple urinary free or unconjugated cortisol ELISA which would allow measurement of both urine and plasma cortisol on the one ELISA plate. This paper describes for the first time an ELISA f...
متن کاملUrinary free cortisol is unrelated to physiological changes in urine volume in healthy women.
To the Editor: Urinary free cortisol is largely accepted as an accurate means of assessing daily cortisol secretion. A more precise definition of this marker should be “urinary free corticoids” (UFCs), because all competitive binding assays overestimate free cortisol in urine (1 ). Recently, it has been argued that urine volume may be a confounding factor because high fluid intake has been repo...
