With the growth of litigation, and the availability of automated machinery to facilitate laboratory procedure, physicians have adopted routine procedures that may add significantly to the cost of medical care.It has been shown that by using clinical judgment to select which patients should have skull roentgenograms after trauma, saving large sums of money without significantly increasing risk to patients is possible (1). Is this true of other routinely ordered laboratory investigations? As a first step in answering this question, we retrospectively analyzed the abnormal...References1.
