摘要 目的比较二点定标和多点定标方法对C-反应蛋白(CRP)测定结果的影响,探讨免疫透射比浊法检测CRP的更佳的定标方法。方法用全自动生化分析仪二点定标和多点定标方法分别检测180份标本的CRP结果,并对结果进行分组对比讨论,其中CRP﹤20mg/L为低值组,CRP20~40mg/L为中值⑴组,CRP40 ̄80mg/L为中值⑵组,CRP﹥80mg/L为高值组。结果多点定标测定CRP结果与二点定标测定的结果比较,低值组和高值组差异有高度显著性意义(P﹤0.01),中值⑴组差异有显著性意义(P﹤0.05),中值⑵结果差异无统计学意义,二点定标和多点定标检测结果的批内平均变异系数(CV)分别为6.2%、3.8%。,批间平均变异系数(CV)分别为8.4%、5.3%。结论不同定标方法检测CRP对结果有明显的影响,多点定标的平均变异系数优于二点定标。
