The inclusion of a minimum of 2 reference samples in the radioimmunoassay of testesterone and digoxin, and the competitive protein binding assay of cortisol served as a simple and practical index of overall assay performance. Statistical parameters, the mean plus or minus 2 standard deviation limits as well as the % coefficient of variation were determined at 3 clinically significant values for these samples. While a 50% intercept served mainly to indicate standard curve sensitivity, quality control sera provided a valid assessment of annay precision.
在睾酮和地高辛的放射免疫分析以及皮质醇的竞争性蛋白结合分析中纳入至少2个参考样本，作为整体分析性能的简单实用指标。针对这些样本，在3个具有临床意义的值处确定了统计参数，即均值加减2倍标准差范围以及变异系数百分比。虽然50%截距主要用于指示标准曲线的灵敏度，但质量控制血清可有效评估分析的精密度。
