1. A method for quality assurance of a sample analyzer, comprising:
providing a statistical criterion for quality assurance of sample analyzers,
the criterion being created based on a peer group data including a plurality of quality control (QC) measurements generated by running tests on quality control samples on a plurality of sample analyzers in a peer group, and
the criterion including a range having an upper limit and a lower limit comparable with a QC measurement generated by a sample analyzer;
comparing, with the range of the statistical criterion, a target QC measurement generated by running a test on a quality control sample on a target sample analyzer; and
issuing a calibration verification certificate associated with the target sample analyzer based on the comparing of the target QC measurement and the statistical criterion.
