Intended use:

RIDASCREEN®FAST Almond is a sandwich enzyme immunoassay for the quantitative analysis of almond or parts of almond in food. As representative samples for the food groups pastries and sweets the following matrices have been tested during the assay´s development: cereals, cookies, ice cream and chocolate. The assay can be likely used for analysis of other food samples too; this has to be checked by the user.

General Information:

The allergen can be present as an ingredient or as a contamination in raw and cooked products. According to the regulation (EU) No. 1169/2011, almond must be declared on food labels as it can induce allergic reactions. Similar regulations exist e.g. in the USA, Canada, Australia and New Zealand.


  • Widespread testing for cross reactivity (80 matrices have been evaluated).
  • Accuracy: recovery of spiked samples was between 66 – 124 % (mean: 97.8 %).
  • Validated for automates.
