Autoverification is the release of laboratory tests results from clinical instruments to hospital interface, or to the patient record, with no human intervention. Verification rules are inserted in the middleware and/or Laboratory Information System (LIS), based on criteria establishedby the laboratory. As a result, it reduces test turn around time (TAT), ensures that every result is consistently reviewed in the same way, improving the entire verification process and patient safety. The objective of this study was to describe the implementation of autoverification inLaboratory Medicine Service at the Hospital das Clínicas, Federal University of Minas Gerais as well as its impact on the TAT. Twenty-six automated chemistry assays were chosen. They were fully automated including internal quality control, interfaced with LIS, available 24hours, seven days a week. Rules were set up in the middleware and in the LIS. Instrument flags, evaluation of sample integrity, test linearity, delta check and critical values were used to construct the verification algorithms. The impact of autoverification on the process TAT andthe rate of tests results automatically released were analyzed. Tests TAT were significantly reduced up to 97% in some tests. The rate of tests released within 120 minutes after specimen receipt was improved from 25.5% to 70% after autoverification implementation leading to amore consistent reviewing process of test results, efficiency and improved patient safety.
