6.35 Figure 2 shows two components of bias, referred to here as method and laboratory components of bias. The method bias arises from systematic errors inherent to the method whichever laboratory uses it. Laboratory bias arises from additional systematic errors peculiar to the laboratory and its interpretation of the method. In isolation, a laboratory can only estimate the combined bias. However, in checking bias, it is important to be aware of the conventions in force for the purpose at hand. For example in much Food regulation, regulatory limits are set in terms of the results obtained by the standard method. Bias arising solely from the particular method (see Figure 2) is therefore compensated for, and comparability with other laboratories using the same method is the main concern. The overall bias determined by a particular laboratory during validation should then be compared with any reported bias for the regulatory method.Ув. коллеги, как перевести данный термин? Измерения с погрешностями? Погрешности измерений? Отклонения, смещения? У это bias миллион значений...
