Abstract
A total of 2012 venous blood samples of healthy individuals were determined for leucocyte counts. The samples were taken between 9.00 to 12.00 a.m. Samples of 503 males and 504 females were examined by manual method, while another 502 males and 503 females were counted by electronic or automatic machine. The results were evaluated by Student’s t-test. The mean + standard deviation of ages in the manual group was 30.9 + 8.6 years for males and 27.4 + 7.7 years for females. They had a mean + standard deviation of total leucocyte counts 7003.78 + 785.76 cells per cu.mm. for males and 7028.83 + 778.09 cells per cu.mm. for females. There was no significant statistical difference (p=0.98981). The mean + standard deviation of ages in the automatic group was 29.5 + 7.4 years for males and 29.3 + 7 years for females. The mean + standard deviation of total leucocyte counts was 6482.68 + 1267.98 and 6819.89 + 1252.55 cells per cu.mm. for males and females respectively. the difference was not significant (p=0.98194). There was no significant statisfical difference in total leucocyte counts
1. between manual and automatic method
2. between males and females
The average + standard deviation of total leucocyte counts of 2012 healthy individuals was 6924 + 1053 cells per cu.mm. The small variation of leucocyte counts among subjects aged 10 to 50 years was also observed.
