Abstract

Several lines of evidence are presented which suggest that psychological response to the venipuncture procedure ['forcibly restrained on rubber mattress in order to perform venipuncture'] may be a major determinant of 'baseline' variability in growth hormone levels. The liability of this system appears to be such that venipuncture effects may occur within the period of a few minutes required for a single venipuncture.
