摘要

目的:建立基于WS/T 356—2024 《参考物质互换性评估指南》的新型、可视化体外诊断试剂干扰研究方法。方法:基于WS/T 356—2024《参考物质互换性评估指南》评估原理,通过Deming回归和95%置信区间分析,系统评估血红蛋白、甘油三酯、胆红素及人血清白蛋白等干扰物对B型钠尿肽(BNP)检测试剂的影响;通过新评估方法与WS/T 416—2013《干扰实验指南》经典方法的评估结果进行一致性评价,验证新方法的可靠性。结果:基于WS/T 356—2024《参考物质互换性评估指南》建立的干扰研究新方法与WS/T 416—2013《干扰实验指南》中的方法相比,干扰物筛查结果完全一致,均识别出血红蛋白、甘油三酯、胆红素和人血清白蛋白为干扰物。在剂量效应分析中,两种方法确定的各干扰物最大允许无干扰浓度亦完全一致(血红蛋白500 mg·dL-1,甘油三酯3000 mg·dL-1,胆红素20 mg·dL-1,人血清白蛋白1500 mg·dL-1)。新方法通过Deming回归图实现了结果的可视化判读,显著提升了分析效率与结果判读的直观性。结论:基于WS/T 356—2024《参考物质互换性评估指南》建立的可视化干扰研究方法可靠、有效,与经典方法具有良好一致性,为体外诊断试剂的干扰性能评价提供了新的研究思路。

Abstract

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.
