Abstract

Background: Total testing process (TTP) in biochemistry laboratory is composed of 3 phases; pre-analytical, analytical and post-analytical. Errors in these phases can lead to erroneous results, hence, compromise the patient management. Objective: 1. To document the nature and determine the frequency of errors in all the three phases of TTP using quality indicators (QI). 2. Applying sigma metrics to data obtained. Study Design: Prospective cross-sectional study. Settings: Clinical Biochemistry Laboratory, at AIMSR, Bathinda, Punjab India. Duration: June 2023 to Nov 2023. Methods: Quality indicators were used to screen errors in requisition forms and samples received in clinical chemistry for analysis. Results: During analysis of 22320 samples, a total of 132 samples were unsuitable for testing and reporting, this resulted in 0.59% of rejection. Out of total 132 rejections, 99 (75%) were in pre-analytical phase, 11 (8.3%) in analytical phase and 22 (16%) in post-analytical phase. The Sigma score of 5 is seen which is acceptable. Conclusion: The preanalytical error is the most common error. Error is unacceptable in the medical field hence training program for the laboratory and non-laboratory personnel involved should be conducted.
