Abstract: A clinical diagnostic analyzer for performing a virtual crossover study on quality control (QC) material includes a processor, memory, measurement hardware, and an input panel/display. The analyzer acquires data from a peer group relating to a new lot of quality control material to calculate a predicted mean and standard deviation based on that peer group data and adjusted for bias in the laboratory process. As new analyses are run on the new lot of QC material, the predicted mean and standard deviation are updated to incorporate the actual data on a weighted basis.

Abstract: A clinical diagnostic analyzer for performing an automated crossover study on quality control (QC) material includes a processor, memory, measurement hardware, and an input panel/display. The analyzer prompts a user to load a QC specimen, and to instigate testing and analysis to determine a mean and a standard deviation for the new material. Associated methods for using one or more clinical diagnostic analyzers to calculate a new mean and standard deviation for a new QC material, reduce error in the calculated mean value, and to reduce the total number of days to complete a crossover study are also disclosed.
