Total, Differential and Absolute Leukocyte Counts and Sedimentation Rates for Healthy Children

It is the purpose of this article to supply more accurate data than have heretofore been available on total, differential and absolute leukocyte counts and on sedimentation rates for healthy children 8 to 14 years of age. 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 have been or will be reported elsewhere. 1 (Footnote continued on next page) Examination of the literature reveals that there are almost no studies by modern methods of the total, differential and absolute leukocyte counts for strictly healthy American children in the age group under consideration. Such figures as are available have been based almost entirely on studies of sick children, although these children were thought by the investigators to have illnesses not likely to affect the leukocyte count. 2 Carstanjen, 3 Karniski 4 and Perlin 5 reported
