Abstract: Methods are provided for end users of diagnostic measurement procedures to prepare quality controls having desired analyte recoveries, estimate recoveries of quality controls already prepared, and compare estimated and measured recoveries. To prepare a quality control containing a particular analyte, a desired recovery of a measurement procedure for the analyte can be scaled by a correlation factor to obtain a target nominal concentration of the analyte in the quality control. Alternatively, the nominal concentration of an analyte in a quality control can be scaled by a correlation factor to obtain a predicted recovery of a measurement procedure for the analyte. The correlation factors can be based on recovery data previously obtained using the measurement procedure and optionally one or more reference procedures, and can be calculated using regression analysis of these data. Each quality control can be prepared by dissolving a number of solid beads containing the analyte(s) of interest in a volume of base matrix.

Abstract translation: 为最终用户提供诊断测量程序的方法，以制备具有所需分析物回收率的质量控制，估计已经制备的质量控制的回收率，并比较估计和测量的回收率。 为了制备含有特定分析物的质量控制，可以通过相关因子来缩放分析物测量程序的期望回收，以获得质量控制中分析物的目标标称浓度。 或者，质量控制中的分析物的标称浓度可以通过相关因子来缩放，以获得对分析物的测量程序的预测回收。 相关因子可以基于先前使用测量程序获得的恢复数据和可选的一个或多个参考程序，并且可以使用这些数据的回归分析来计算。 每个质量控制可以通过将包含目标分析物的许多固体珠溶解在一定体积的基质中来制备。

Abstract: Solid beads each containing a selected quantity of analyte are combined and a liquid base matrix that contains attributes of a biological fluid that is to be assayed, together constitute a kit from which a laboratory technician can, at the point of use, prepare a liquid control for a particular analyte, and preferably a series of such controls at different levels of the same analyte customized for a particular assay.
