1. Intended use

The Lateral Flow Walnut (Art. No. BLH707-15) with included hook line from bioavid is an immunochromatographic test for the sensitive and qualitative detection of walnut residues on surfaces (e.g. swab test for the hygiene control in food production lines), in cleansing and process water (CIP water) and food samples. The integrated hook line prevents false negative interpretation of high positive samples.

**NEW**

All for swabbing now included in the kit!

2. General information

- Walnut contaminations in food possibly elicit hypersensitivity in sensitive persons. Food production lines have to be free of residues to prevent these allergic reactions. The effectiveness of cleaning can be verified by using the Lateral Flow Walnut Swabbing method.

- Dipsticks are an easy to use method and provide a fast and reliable analysis. The application of our bioavid dipsticks is very simple and can be handled by untrained personnel. All bioavid test kits can be stored at room temperature and therefore they are an ideal tool for direct testing in production facilities. The bioavid test kits contain the complete equipment for the analysis.

Highly colored or acidic/alkaline solutions have to be extracted with the Absorbent buffer (BS810-25). The buffer decolors or neutralizes solutions to avoid false positive results (e.g. highly colored juices).

For the analysis of non-validated samples, the document “SOP Verification Solid Sample Test” (standard operation procedure) and a detailed instruction for use can be used.
