Abstract:Sigma metrics, implemented by clinical laboratories, utilize the performance of assays to evaluate both precision and accuracy by considering the recommended total allowable error (TEa). The study aims to evaluate the performance of 48 analytes (chemistry and immunological) performed in a tertiary care hospital laboratory and compare them with the TEa recommended by CLIA 1988 and 2024 guidelines. This study, conducted at the Biochemistry Department of Medanta Hospital, Lucknow, Uttar Pradesh, India, utilizes r… Show more
