ISO 14675IDF186:2002给出了基于竞争性酶免疫测定法测定牛奶和奶制品中黄曲霉毒素M1含量的筛选方法的使用指南。 出于法律目的，阳性酶免疫测定结果需要通过公认的参考方法进行确认。然而，取决于检测是否符合下文给出的质量标准，酶免疫测定可用于常规质量控制，尤其是当需要记录不存在高于监管限度的黄曲霉毒素M1时。

ISO 14675|IDF186:2002 give guidelines on the use of screening methods used for the determination of aflatoxin M₁ content in milk and milk products, based upon competitive enzyme immuno-assays. For legal purposes, positive enzyme immunoassay results require confirmation by an accepted reference method. However, depending on whether the test complies with the specifications given hereafter, enzyme immunoassays can be used for routine quality control, especially when the absence of aflatoxin M₁ above the regulatory limit needs to be documented.
