Value of profiling liver function in the elderly.

The value of measuring three routine tests of liver function was assessed prospectively in 523 geriatric patients. Abnormalities were found in 27% of patients and were clinically helpful in half of these cases. Profiling liver function, without clinical indication, revealed abnormal results in 17% of patients and was important in one-third of these (6% of total). The two most important diagnoses were unsuspected osteomalacia and gall stone disease.
