Critical Values Analysis of Biochemical Parameters in A Tertiary Care Hospital: A Retrospective Study

Critical value reporting is one of the requirements for laboratory accreditation and is an important aspect of quality assurance regarding reporting of results. This reporting of patient results specially critical values should be clear, accurate and rapidly communicated to clinicians.

Methods: Biochemical parameter results of one year (January 2020 to December 2020) were retrospectively evaluated in terms of identification of critical values generated from the testing of samples on siemenes analyser and their association with entries in the call back register in a biochemistry lab situated in a tertiary care hospital. Statistical analysis was conducted using Microsoft Excel 2016 program.

Result: A data of 79773 tests were analysed, and 2658(3.3%) critical alerts were generated by the Siemens auto analyzer. of these only 1649(2%) were recorded in the call back register of critical alert.
