Hourly Changes in Serum Cholesterol Concentration

Abstract
Further evidence has been obtained to indicate that the concentration of serum cholesterol can vary widely during the course of a few hours in certain individuals. The data are consistent with a hypothesis that changes in the concentration of serum cholesterol may relate to the anticipation of an event as well as to the event itself. Similarity in the hourly variation in serum cholesterol concentration occurring among eight carefully selected subjects, during control as well as during test periods, is note-worthy.
