Estimation of alert and change limits and its application in the plausibility control

摘要

In the clinical laboratory, one of the most objective ways to perform the final review of patients' measured values is the use of computerized plausibility control (i. e., set of procedures used to decide whether a patient's measured value is valid according to established clinical and biological criteria). This study is focused on the estimation of alert and change limits to be applied to detect doubtful patients' measured values. These limits are useful to improve the final review of patients' measured values since these limits are produced objectively and are selected according to the clinical laboratory needs, letting the clinical laboratory professional staff to save time and effort.
