THE LEUCOCYTE COUNT IN OLD AGE
Department of Geriatric Medicate, University of Glasgow and Department of Haematology, Ruchill Hospital Glasgow
The total leucocyte count was measured in 480 old people living at home, and differential counts carried out in 468. The total leucocyte count and the absolute polymorph and lymphocyte counts were found to have a lognormal frequency distribution, the differential counts a normal distribution.
The range of total leucocyte counts was 31008900/mm3, of polyrnorph counts 18006500/mm3, and of lymphocyte counts 7003500/mm3. Comparison with published data suggests that old people have a tendency to leucopenia, due to lymphopenia.
