The procedure for preparing standard solutions of surfactants (sodium dodecyl sulfate and benzalkonium chloride), alanine aminotransferase, and aspartate aminotransferase with the appropriate activity has been defined. An algorithm was developed for estimating the extended uncertainty of the measurement result (calculation of the experimental mean square deviation (hereinafter - SLE) of a series of measurement results, evaluation of the homogeneity of the series of results according to the Cochran criterion, calculation of the SLE value, which characterizes the repeatability of the results obtained in conditions of convergence and reproducibility, estimation of the values of the standard and extended uncertainties of measurement results.  Product Description popup.authors popup.nrat_date 2023-01-23 Close
