It is the purpose of this article to supply more accurate data than have heretofore been available for total, differential and absolute leukocyte counts and sedimentation rates of healthy adults 19 years of age and over. This is one of a series of papers on hematologic standards for healthy persons from birth through adult life. The data for other age groups has been or will be reported here and elsewhere.1
The values given in most textbooks appear to have been copied from one book to another since the very early studies.
