Clinical parameters of the normal baboons (Papio species) and chimpanzees (Pan troglodytes)

Improved equipment and advanced progressive techniques by scientists using baboons and chimpanzees in biomedical research have resulted in improved clinical laboratory data. The use of state-of-the-art clinical laboratory instruments, methodologies with improved accuracy, and an increased variety of individual tests routinely requested and performed has necessitated the comparison of current data with prior data produced in our laboratory and with those values reported in the literature. In addition to an expanded hematologic profile, including red blood cell distribution width and mean platelet volume, and a more comprehensive chemical profile of 28 individual tests, additional data collected included values for coagulation profiles, arterial blood gases, serum protein electrophoresis, and urine osmolalities. Samples for evaluation were obtained from clinically normal sedated adult baboons (Papio species) and chimpanzees (Pan troglodytes) and processed conventionally according to Good Laboratory Practice Act standards. Arithmetic means were calculated, values of 3 standard deviations or greater were eliminated, and means were recalculated to include 2 standard deviations. All data correlated well with prior in-house values, and no remarkable differences from established data were detected, thus indicating the reliability of past and present data. Data compared favorably with normal clinical values established for humans.
