OnSite® III Allergen Test Kits can be ordered for any of the following analytes: 

  • Almond
  • Casein
  • Cashew
  • Coconut
  • Crustacean
  • Egg
  • Gluten*
  • Hazelnut
  • Macadamia
  • Milk 
  • Mustard
  • Peanut
  • Pine Nut
  • Pistachio
  • Sesame 
  • Soy
  • Walnut/Pecan

* gluten kit requires additional supplies and separate extraction protocol.

 

Rapid testing is an important component of any food safety plan. Using rapid tests can provide additional reassurance as to the allergen-free status of incoming ingredients, validate the efficacy of a food production facility’s allergen cleaning protocol, and verify that those cleaning protocols have been undertaken successfully and safely.
 
OnSite® III Allergen test kits are particularly helpful because of their low detection limits, simple operating procedures, and modular design. They are suitable for food manufacturing facilities and commercial kitchens that work with one or more allergens — and also for facilities that make allergen-free claims. 

OnSite® III Allergen can be used on raw ingredients, finished products, rinsewater, and surfaces. Analyzing surfaces does require the separate purchase of OnSite® Accessory kit. OnSite® Allergen Multiplex Tree Nut cannot be used to analyze foods. 

OnSite® III Allergen kits are each designed to react to a specific allergen. For environments where multiple allergens may be present, kits may be combined as needed. With the exception of gluten, all allergens share a common extraction protocol. This means that one extracted sample can be used to detect several allergens at the same time. 

Test kits should be kept between 2°-8°C, in the refrigerator. This preserves kit shelf life and sensitivity.

Complete Instructions for Use are included in each test kit. Tests are simple to run and no previous knowledge is required. Contact your distributor for more details.

No. While the three-line design does distinguish between low and high levels of allergen, a precise value is not possible. 

In situations where a precise value is required, ELISA analysis should be undertaken by trained personnel.

OnSite® Allergen Multiplex Tree Nut

This convenient lateral flow test kit quickly detects traces of tree nut protein in rinsewater and on surfaces.

Allergen Multiplex Tree Nut at a glance:

  • Test works on surfaces and rinsewater
  • Simultaneously detects almond, cashew, hazelnut, pecan, pistachio, walnut
  • Detects as little as 1-5 mg/kg (ppm) of tree nut protein in rinsewater or  10μg/ 100 cm2 on surfaces
  • Requires no equipment
  • Results in less than 20 minutes
  • Sensitive to coconut protein at levels above 50 mg/kg (ppm)

Tree nut allergies are among the most common food allergies for both children and adults. Accordingly, many countries consider tree nuts to be a major food allergen requiring careful labeling and hazard management. And because many individuals with tree nut allergies are not allergic to all tree nuts but only to some, allergen legislation frequently requires each specific nut to be labeled and handled distinctly. For example, a person may need to avoid cashew and pistachio only — and so a product label must indicate the presence not just of “tree nuts” but also detail which nuts are included. 

In some cases, specific allergen tests for each different tree nut can help provide this clarity. Testing incoming ingredients, surfaces, and finished products for the presence of almond, or walnut, hazelnut, macadamia, etc. is an important part of many food safety plans. In other cases, a simple protein swab may provide sufficient safety data.
 
However, running multiple test kits at once is expensive and time-consuming — and general protein swabs are neither sensitive nor specific to allergens. 
The OnSite® Allergen Multiplex Tree Nut Rapid Test offers the sensitivity and specificity of an allergen LFD test with significant cost savings. It is suitable for food and beverage production facilities that work with one or several species of tree nut — and also for facilities that are entirely nut-free. 
 
Commercial kitchens and production facilities can easily meet their safety needs by incorporating this single test. Because OnSite® Allergen Multiplex Tree Nut Rapid Test identifies traces of almond, cashew, hazelnut, pecan, pistachio, and walnut, it offers flexibility for a variety of hazard scenarios. And because it requires no equipment or specialized training, it can be used anywhere that food is made. 

No. The OnSite® Allergen Multiplex Tree Nut test kit is targeted at the six most common tree nuts. 

Definition of “tree nut” vary by country, but nearly always include more nut species than these six. If you require information about a nut other than almond, cashew, hazelnut, pecan, pistachio, or walnut — contact your distributor to see if an OnSite® III Allergen kit is available for your specific need. 

OnSite® Multiplex Tree Nut is strictly for surfaces and rinsewater. It cannot be used to analyze foods. 

In addition, OnSite® Multiplex Tree Nut is designed to provide a single “detected” or “not detected” signal when any or all of the target analytes are found in detectable quantity. This means that the presence of sufficient almond or cashew or hazelnut or pecan or pistachio or walnut — or any combination of those nuts — will trigger a positive (“detected”) result. 

If more targeted information about any one specific allergen is needed, the relevant OnSite® III Allergen Test Kit can be used. 

Test kits should be kept between 2°-8°C, in the refrigerator. This preserves kit shelf life and sensitivity.
