Introduction: With advance in technology, many instruments with wide variety of principle or technologies are available in market and in laboratory to conduct sample processing in time bound period. To fulfill the laboratory quality goal, it is essential that result matching be obtained in all used biochemical analysers for examinations. Documented evidence of method/instrument comparison can be used in future for quality improvement purposes.
Aim: To assess and compare equivalence and harmonisation in glucose results produce by ERBA XL-640 vs ERBA XL-1000 in clinical biochemistry laboratory.
Materials and Methods: A comparative study was carried out by results comparison of glucose measurements obtained in two automated systems ERBA XL-640 and ERBA XL-1000 in Clinical Biochemistry laboratory at Surat Municipal Institute of Medical Education and Research between June 2021 to October 2021, based on protocol EP09-3A of result harmonisation and review article-method comparison. The results value were compared according to the total allowable error in Clinical Laboratory Improvement Amendments of 1988 (CLIA’88). Results were analysed by visual and quantitative analysis method Regression analysis and Bland-Altman plot, Method evaluation chart (Normalised MEDx chart).
Results: Total of 48 samples were run within the batches and between the batches and quantitative analysis of difference was done. It is acceptable at medical decision level 40 mg/dL, 120 mg/dL
and 180 mg/dL with comparison to total allowable error.
Conclusion: The present study concluded that the comparison of ERBA XL-640 and ERBA XL-1000 for glucose examination by end point method {Glucose Oxidase-Peroxidase (GOD-POD) method} is acceptable and can be used interchangeably without repeat at major clinical decision levels.
