Internal quality control in virology: validation of immunoassays using a personal computer spreadsheet.
Design of a spreadsheet to evaluate the performance of internal quality control sera used for the validation of immunoassays in virology is described. Developed using Microsoft Excel 97, it can set target limits and analyse control data by application of Westgard quality control rules. It also provides a permanent record of all relevant information concerning each assay run, including action taken to rectify unacceptable performance.
