Effect of age on liver function.
Serum concentrations of bilirubin, alkaline phosphatase, and GOT as well as the retention of BSP and 131I-rose bengal were determined in 43 normal subjects over 50 years old for the purpose of evaluating age-dependent variations. The normalcy of the liver in all subjects was confirmed by biopsy. The values of serum bilirubin, alkaline phosphatase, and GOT were unaltered with increasing age. Age also had no effect on the retention of BSP and 131I-rose bengal, in contrast to some previous studies in which the normalcy of the liver was not satisfactorily established. No variations between the sexes were seen in our study. The median of the 45 minute BSP retention test was 4.2 percent, with a ninth decile of 7.5 percent. The median of the retention of 131I-rose bengal was 32 percent, with a ninth decile of 39.4 percent.
