自1969年7月以来，每隔14天就将相同血清的一部分送往联合王国的临床化学实验室。每次血清调查的结果在最初收到标本后11天内报告给390名参与者。在调查的前18个月，没有看到结果的总体改善。因此，计算每个实验室持续产生接近所用方法平均值的结果的能力总结，并报告为单个数字，即方差指数，并定期发送给所有参与者，同时发送其他参与者方差指数的直方图分布。随后的整体结果的改善进行了说明。
Since July 1969, portions of the same blood serum have been dispatched to clinical chemistry laboratories in the United Kingdom at 14-day intervals. The results of each serum survey were reported to each of the 390 participants within 11 days of their originally receiving the specimen. During the first 18 months of the survey no overall improvement in the results was seen. Therefore a summary of each laboratory's ability consistently to produce results close to the mean of the method used was calculated and reported as a single figure, the variance index, and sent to all participants at regular intervals together with a histogram distribution of the variance indices of other participants. The subsequent improvement in the overall results is described.
