Note: We only carry the cashew lateral flow tests.

The Cashew (Anacardium occidentale) belongs to a group of foods, commonly referred to as “tree nuts”. This group of foods is a significant source of allergens, and cashews are a frequent cause of food allergy. Consequently, there is a need for a sensitive and reliable test for the detection of specific tree nut allergens in foods. Any such test must be able to detect a heat stable protein component, otherwise false negative results could occur with samples that have been highly heat treated.

Intended Use

This test kit is designed for use in the qualitative determination of cashew nut residues obtained from sampling foods (solids, powders, and liquids) and on surfaces. The test is intended for laboratory use only and should only be performed by trained personnel.

Assay Principles

The AllergenControl™ Cashew Residue Lateral Flow Test features polyclonal antibodies directed against cashew nut proteins configured in both sandwich and competitive format. To operate the kit, the sample is first subjected to a short extraction step. The sample extract is then directly applied to the lateral flow device sample port, where it is allowed to migrate across the reagent zone thus enabling visualization of the Sandwich Test Line (T) and Competitive Test Line (0) results. In addition, the reagent zone includes a Procedural Control Line (C) to minimize the potential for false negative outcome
