[Effect of age and sex on the enzyme activities of serum aspartate and alanine aminotransferases].

Reference values of ASAT and ALAT are calculated from all the results over a period of two years. For each test age- and sex-related variations were assessed and reference values were estimated for six different age groups. The activities of both enzymes are sex independent. The activity of ASAT decreased with increasing age whereas the activity of ALAT did not show different reference values between the age categories.
