Variability associated with analytical methods used to measure aflatoxin in agricultural commodities.

A total of 1019 analytical precision estimates obtained from collaborative studies for mycotoxins published through 1991 were sorted by type of variance measurement, type of analytical method and type of agricultural commodity.  Precision estimates for total aflatoxin were sorted into 2 precision measurements (inter-laboratories and intra-laboratory), 3 analytical methods (TLC, LC and ELISA), and 11 agricultural commodities.  When results were pooled across all agricultural commodities, LC had the lowest analytical variability while ELISA had the highest.  For a given method, inter-laboratories variability was approximately double the intra-laboratory variability.  These analytical variability estimates can be coupled with previously determined variability estimates of sampling and sample preparation to determine the performance associated with specific test procedures used to inspect agricultural commodities for aflatoxin.
