Abstract：
OBJECTIVE: To analyze the results of international proficiency tests for aflatoxin determination and to identify the requirement of quality assurance and control in mycotoxin analysis.
METHODS: By the use of Z-scores, the results of aflatoxins from international proficiency tests were analyzed and the critical control points in experimental operation were discussed.
RESULTS: The absolute values of the Z-scores of aflatoxins were less than 2, indicating that the results from the laboratory were satisfactory. The sampling and testing method had very important effects on the detection results.
CONCLUSIONS: The results of the international proficiency tests of aflatoxins suggested that to strengthen the critical control points in the experimental operation can effectively improve the accuracy and reliability of the determination results.
