How is MUC applied to interpretation of the results on the certificate?

The expanded measurement of uncertainty should be subtracted from and added to the analytical result after correction for recovery. The true value would lie between this range.

Eg; Paprika tested for Aflatoxin B1 (Acceptable limit is 10ug/kg)

The analysis of the paprika gave the following results for aflatoxin B1 (analytical result with corrected recovery still to be determined);

3,0 ug/kg (40% expanded MUC, 75% recovery) = 4.0 ug/kg +/- 1.6ug/kg i.e range 2.4- 5.6ug/kg
