Human Plasma Steroid and Electrolyte Concentrations between 0800 and 1600 Hours
Abstract
The purpose of the present study was to determine whether or not significant changes would occur in plasma steroid and electrolyte levels as a consequence of a 4-hour sampling procedure. Two venous blood samples were collected from each of 460 healthy young adult males, with a 4-hour interval between samplings. There was no consistent change in total 17-hydroxycorticoid levels between 0800 and 1600 hours. Very small yet statistically significant increases in plasma sodium were found following the 4-hour periods between samples. Potassium concentration increased in three of the five time groups, only two of these increases being significant.
