请使用已经确定不含组胺成分的样品进行检测。可以使用其他检测方法进行检测，例如Check Color Histamine等方法，颜色没有变化的话就说明没有发生反应颜色有误，可以使用该产品进行测定。

弊司研究认为，大多数没有经过处理的生鱼是可以进行测定的， 详细情况可以联络我们。检测结果并不是每次都会相同，还请客人自行确认是否可以使用该试剂进行检测。

Histamine Check Swab使用的试剂，当组胺脱氢酶遇到组胺分解时产生的抗氧化成分和发色物质反应会产生紫色的变化。因此，如果含有较多的抗氧化成分的话，就会与发色物质 进行反应，即使不含有组胺也会有颜色产生。

出现了反应颜色有误的样品，通过加热也有可能被改善。发生反应颜色有误是由抗氧化成分引起的，因此请尽量多搅拌样品，使空气充分进入样品。加热的时候，请向50ml的塑料试管等容量更大的容器内放入少量（5ml左右）样品进行加热。另外，稀释样品的时候不建议用水，使用pH8.0、0.1M的EDTA・2Na溶液效果会更好。但是，样品不同也有可能出现即使加热也不被改善的情况。
