AllergyScreen® and AlleisaScreen® are two test systems to detect allergen-specific IgE in human serum. Customers can be provided with the necessary test strips and the corresponding hard- and software (camera, scanner, testing equipment, robotics).

Comparative studies

A comparison with an established single allergen determination System (SADS) and skin test has shown that the Allergy-Screen® System offers a highly effective method for determining a patient‘s comprehensive specific sensitisation pattern. The sensitivity and specificity of the system is very similar to skin testing, and corresponds to a conventional single allergen system.

What‘s more, the Allergy-/Alleisa-Screen® systems achieve precise results at a low cost and with a minimum material expenditure.

A complete study overview is available for registered customers. Visit the customer service area for further information.
