Base line hematological values were determined for 79 male and 62 female monkeys Macaca mulatta. One group of 5 males and 6 females over 3 years of age was sampled weekly for 40 weeks. A second group of 130 monkeys was subdivided according to sex and age males vs females, under 3 years of age vs over 3 years of age. These animals were sampled biweekly for 12 weeks. Age- and sex-related influences on the various parameters were evaluated. In the first group, the males red cell count, hemoglobin, and hematocrit were significantly higher p .001 than the corresponding values for females. In females the white cell count, platelet count and erythrocyte sedimentation rate were significantly higher .05 P .01 than in males. In the second group, sex-related differences were seen in both age categories. Males under 3 years had significantly higher p .01 hemoglobin, hematocrit, lymphocyte and clotting time values than females of the same age group. In females under 3 years, the segmented neutrophil value was higher p .01 than in males under 3 years. In the animals over 3 years of age, males had higher values for red cell count, hemoglobin, hematocrit, lymphocyte, clotting time all p .01 and white cell count .05 p .01. As in the younger age group, the segmented neutrophil value was higher p .01 in females. Three age-related differences were found. Males over 3 years had a higher red cell count .05 p .01 but a lower hemoglobin p .01 than males under 3 years. Females under 3 years had a higher white cell count p .01 than the older females.
