Table 1. Equivalent concentrations obtained with Access Ostase, when the value measured with the ISO-PAL is 27 U/L and 53 U/L, Spearman’s rho coefficient of correlation and Kendall's W coefficient of concordance between the analyzed methods to classify identically the patients when they present values ≤ 27 U/L, between 27 and 53 U/L, and ≥ 53 U/L with the ISO-PAL.
