Problems and solutions on autoverification of coagulation test

doi:10.3969/j.issn.1673-8640.2022.06.018

Abstract

Abstract:

The autoverification of reports is the future development trend of clinical laboratories,which can significantly shorten the laboratory sample turn-around time and improve work efficiency. The autoverification of coagulation tests is less used in clinical laboratories,due to many problems such as the identification of unqualified samples and the complex rules of autoverification. The basis for the implementation of autoverification is strict and standardized quality control of pre-analysis and interconnection of information systems. Based on the premise of accurate results,clinical laboratories can set appropriate autoverification rules according to its own conditions,continuously optimize the autoverification rules for coagulation test,and gradually increase the autoverification pass rate of clinical laboratory test.

Key words: Autoverification, Coagulation test, Laboratory information system, Laboratory automation
