At present only a limited range of detection kits are available commercially. As this is a rapidly expanding field the current manufacturers have not been listed.

Instead it is hoped that the reader will be equipped with an understanding of the techniques involved and what criteria should be specified for the assay. The following questions should be raised when considering the use of the various methods:

• What are the detection limits required?

• How sensitive is the assay under the conditions in which you wish to use it?

• How specific is the assay for the matrix in which you are trying to detect the allergen?

• What is the percentage recovery of your extraction procedure?
