Caution
- False positive and inaccuracy in histamine content assay may occur depending on assay samples and pretreatments. Please use another assay method if accurate histamine content must be identified.
- False Positive Prevention by Preprcessing:
When measuring with Histamine Check Swab, if the sample contains interfering components such as antioxidants,false positive may occur, causing the reagent to turn purple even when no histamine is present.
By using 4% acetic acid solution instead of water when diluting food materials and setting the reaction time to 25 minutes*, false positive can be prevented. For further detail, click here.
