15.3.2 Precision

The precision was evaluated by using the commercially available control solution Medi-Test
Control, manufactured by MACHEREY-NAGEL, Düren, Germany. This Control is used for
daily routine system check of the URYXXON
set (Medi-Test Control N = level 1 (N): negative-normal, Medi-Test Control P = level 2 (P):
positive values). Repeatability and reproducibility amount to 100 % in all cases. The results are
summarized in the following table.
