Diagnostic tests represent a significant percentage of medical costs. Knowledge of test ordering principles and a few testing strategies can significantly reduce unnecessary testing and costs. Awareness of the limitations of screening, less frequent monitoring of known abnormalities, reduced utilization of stat. tests and test panels and better use of existing information will improve the efficiency and accuracy of diagnostic testing.
