Hematologic values of captive golden lion tamarins (Leontopithecus rosalia): variations with sex, age, and health status.

Blood samples obtained from 104 captive golden lion tamarins (Leontopithecus rosalia), collected over a 7-year period, were analyzed for hematologic values. Variations associated with sex, age, and health status were identified. Females had higher total plasma protein values, while males had higher numbers of basophils, hematocrits, and hemoglobin concentrations. Adult tamarins had higher erythrocyte and leukocyte counts, more neutrophils, basophils, and eosinophils, and higher hematocrits and hematocrits, hemoglobin concentrations, erythrocyte indices, and total plasma protein. Decreased numbers of monocytes and eosinophils and increased numbers of leukocytes, neutrophils, bands, and basophils also were observed with abnormal status.
