Study of Pre-Analytical Errors in Laboratory & Steps to Improve

Abstract

Objectives: Pre-analytical errors decisively influence the total laboratory errors and consequently the diagnostic accuracy. The following were the objectives of the study. 1) To detect the percentage of pre-analytical errors in venous specimens in Laboratory. 2) To categorize these pre-analytical errors. 3) To formulate steps of corrective measures to avoid such type of errors. Study Design and Result: Type of Study - Retrospective study. Study period - 12 months (June 2015 to May 2016), documenting the frequency and type of pre-analytical errors. Results: Total number of pre-analytical errors detected in the period of 12 months’ study were 180. Improper timing of specimens, hemolyzed & clotted specimens and improper requests were the major concerns followed by delay in specimen transport. Conclusion: Pre-analytical phase is an important component of Total Laboratory Quality. Pre-analytical errors are not inevitable and can be avoided or minimized with diligent application of quality control, continuing education, effective protocols, and standardized procedures for effective blood collection systems to ensure total Quality patient care.
