The OnSite® Allergen Multiplex Tree Nut test can detect as little as 1-5 mg/kg (1-5 ppm) of tree nut protein in rinsewater or 10μg/ 100 cm2 on surfaces. Sufficient amounts of any or all of the following tree nut proteins will trigger a positive result: almond, cashew, hazelnut, pecan, pistachio and walnut. In addition, coconut will trigger a positive result at or above a level of 50 mg/kg (ppm) of protein in rinsewater.
The OnSite® Allergen Multiplex Tree Nut test kits require refrigeration. No additional equipment is required, although a calibrated pipette is suggested for maximum accuracy.
OnSite® Allergen test kits are made by Microbiologique in an ISO:9001 facility.
