Abstract:

Risks are inherent in each step of whole testing process. Delta checks based on individual patients' data are methods for mitigating these risks. Delta checks can be used as a complementary tool for traditional laboratory quality control to determine issues that quality control materials may not address. It can be applied into different phases in whole testing process,including determining misidentified and mishandled specimens,true patients' changes,instrumentation and personal errors,as well as the evaluation of point-of-care testing(POCT). The review introduces the application of delta checks in POCT and pre-examination,intra-examination and post-examination phases,including selecting candidate analytes,establishing monitor parameters,setting limits and the evaluation of usefulness,hoping to provide a reference for clinical laboratories.

Key words: Quality control, Quality assurance, Delta checks, Laboratory errors
