This invention is a novel method for analysis of data that is produced by 
test equipment. The preferred embodiment is data produced by liquid 
chromatography tandem mass spectrometry (LC-MS / MS) equipment, using 
industry standard methods to generate the initial data from the 
test equipment. The invention is a method for 
processing of the data to promptly produce accurate, reliable, and meaningful data that can be used for critical decisions. The unique benefit of the method is to correct the multiple measurement and calculation errors that are inherent in the operation of laboratory equipment. Prior methods result in errors based on circumstances that are difficult to control, accuracy-related errors in 
machine measurements, and fundamental mathematical errors in the 
data processing software that used with the laboratory equipment. As an added benefit, this novel method allows comprehensive simultaneous measurement and calculation of correlation of any and all 
peptide pairs in a 
single measurement, with the capability to support repeated measurements with changed conditions over time. This novel method allows robust, detailed, and comprehensive measurements of 
peptide activity and function, which results in substantial improvements over prior methods in accuracy, reliability, and efficiency.
