Using a Technicon SMAC continuous-flow instrument, we compared a liquid quality-control material ("Decision level 3," Beckman) with two different lyophilized quality-control materials. The variances for 19 analytes in the three materials were significantly greater for Decision than for the Ortho Abnormal and the Omega II lyophilized control sera (p less than 0.00001 for each comparison by the omnibus test). The imprecision for Decision was not due to incomplete mixing or carryover. The viscosity of Decision, however, was more than twice that of the two lyophilized control sera or of pooled human serum.
使用Technicon SMAC连续流动分析仪，我们将一种液体质量控制材料（“决策水平3”，贝克曼公司）与两种不同的冻干质量控制材料进行了比较。三种材料中19种分析物的变异度，决策水平材料比奥索异常冻干对照血清和欧米茄II冻干对照血清的变异度显著更大（通过综合检验，每次比较p值均小于0.00001）。决策水平材料的不精密度并非由于混合不完全或残留。然而，决策水平材料的粘度是两种冻干对照血清或混合人血清粘度的两倍多。
