Haematological and biochemical reference values were established from 45 cllnically healthy koalas. Statistical analysis revealed no significant dlfferences for sex and season of sampllng. immature koalas had significantly higher alkaline phosphatase and Inorganic phosphate values, and slgniflcantly lower total protein concentrations due to low globulins values. Enzyme reference values tended to be wlde and could llmit their usefulness in detecting disease. In the reference values for leukocytes, neutrophils and lymphocytes, the inclusion of low values which were not actually seen may interfere with the detection of reduced levels due to disease.
