Table with brief descripive summary for each component (17/2-2003)

Table updated 4/11-2003. According to "The Nordic Trueness Project 2002. Report to participants" (reference IMEP17-1), only one additional decimal for some components are added. The major change is ALP target value from 64.0 to 67.1. As it was decided that in addition to the three Roche Modular instruments, also all Vitros instruments had methods compatible with IFCC (37C) method, the mean value of laboratory mean for CAL changed from 64.0 to 67.1 U/L. Small corrections also to amylase, p-amylase and AST
