Objective: To establish a novel visualized interference study method for in vitro diagnostic reagents based on WS/T 356—2024 "Guideline for Evaluation of Commutability of Reference Materials".Methods: Based on the evaluation principle outlined in WS/T 356—2024 "Guideline for Evaluation of Commutability of Reference Materials", this study systematically assessed the effects of interferents(including hemoglobin, triglycerides, bilirubin, and human serum albumin)on B-type natriuretic peptide (BNP) detection reagents using Deming regression and 95% confidence interval analysis. The results were compared with those obtained using the classical approach described in WS/T 416—2013 "Guide to Interference Testing in Clinical Chemistry" to verify the reliability of the new method.Results: The novel interference study method established based on WS/T 356—2024 "Guideline for Evaluation of Commutability of Reference Materials" demonstrated complete consistency with the classical approach described in WS/T 416—2013 "Guide to Interference Testing in Clinical Chemistry" in terms of interference screening results. Both methods identified hemoglobin, triglycerides, bilirubin, and human serum albumin as interferents. In the dose-effect analysis, the maximum non-interfering concentrations determined by the two methods were also identical: 500 mg·dL-1 for hemoglobin, 3000 mg·dL-1 for triglycerides, 20 mg·dL-1 for bilirubin, and 1500 mg·dL-1 for human serum albumin. Furthermore, the novel method enabled visualized interpretation of results through Deming regression plots, significantly enhancing analytical efficiency and intuitiveness.Conclusion: The visualized interference study method established based on WS/T 356—2024 "Guideline for Evaluation of Commutability of Reference Materials" is reliable and effective, which demonstrates good consistency with the classical method, and provides a new research direction for the interference assessment of in vitro diagnostic reagents.
