Incidence of Pre-analytical Phase Errors: A Retrospective Study in Biochemistry Lab of a Tertiary Care Hospital.
Keywords:
pre-analytical phase, errors, clinical biochemistry, error incidenceAbstract
Objective: Aim of the present study was to find the incidence of errors in pre-analytical phase and various factors contributing to the same. Every laboratory strives to minimize errors at every level of sample analysis. Number of errors in pre-analytical phase is maximum and leads to wastage of resources and time.
Methodology: It is a retrospective study conducted in biochemistry laboratory of a tertiary care hospital. Pre-analytical errors were assigned to various pre-defined categories.
Results: Total of 138240 samples were collected in one year period extending from July 2019 to June 2020. Incidence of pre-analytical errors was found to be 1.6%. 2212 samples out of 138240 were found to have one or the other predefined errors.
Conclusion: 1.6% samples received in biochemistry lab were found to have errors. Errors in requisition form was the most common cause. Such errors can be addressed by training and coordination.
