SKU: H-ALS-100 Categories: ,


Protein residue test, tests for the presence of a broad range of allergens.

Results in 15 – 30 minutes.

No instrument required with this all-in-one test (consumable).

AllerSnap detects any protein residues left on a surface after cleaning. Simply swab a surface, release the reagent and if any residue containing protein is present the reagent will turn purple. The colour change provides a semi-quantitative measure of the surface cleanliness. The more contamination present, the quicker the colour change to purple and the darker the colour.

AllerSnap quickly validates the hygiene of a surface, allowing immediate corrective action to be taken if necessary. The data generated provides vital management information, proof of hygienic practices and evidence of due diligence.

Detects the following allergens:

  • Peanut butter
  • Wheat
  • Egg whites
  • Almonds
  • Sesame
  • Soy
  • Milk powder
  • Shrimp


Monitor the cleanliness of washer disinfectors and surgical equipment in hospitals, dental rooms or the food industry. Useful for training and the promotion of best practices.


  • All-in-one test device
  • Visible colour results in 15 – 30 minutes
  • Built-in colour chart for easy interpretation

  • Breaks through biofilms
  • Sensitive liquid-stable reagent – detects down to 1 micro gram of protein*
  • Suitable for Allergen monitoring
  • Economical – no instrument required
  • Enables immediate corrective action, thus less waste

* Enhanced sensitivity if incubated at 55°C for 15 minutes

Method Comparison for Allergen Tests

Foodstuffs ALLER-Snap Allergen Test (ELISA)
Shrimp 10 ppm 5 ppm
Wheat (Flour) 10 ppm 5 – 75 ppm
Peanut Butter 1 ppm 0.5 – 5 ppm
Egg Whites 1 ppm 4 – 25 ppm
Milk Powder 10 ppm 2.5 – 10 ppm
Soy 1 ppm 2.7 – 5 ppm
Almonds (Raw) 10 ppm 5 – 12.5 ppm
Sesame 10 ppm 5 – 48 ppm


– ALLER-Snap sensitivity levels are based on incubation at 55°C for 15 minutes

– Studies show that the recovery of allergens from surfaces are very variable and inefficient with 4 – 27% recovery when tested by ELISA methods. Sensitivity data shown is based on information available online.

– The first two methods are nonspecific product residue tests. The ELISA method is a specific allergen protein test.

Sensitivity: detects 3 micro grams protein after 15 minutes at 55°C or 30 minutes at 37°C

Shelf Life:

  • 12 month shelf life at refrigerated temperatures (2 – 8°C)
  • 4-week shelf life at room temperatures (21°C)

Delivery content:
