Test for Cow's Milk Allergy Is Non-Invasive

A ready-to-use patch test has been developed for diagnosing cow's milk allergy.

A dry, disc-shaped cutaneous device system holds an active ingredient in powder form on an electrically charged plastic film that is delivered only when placed on the skin. Application of the disc creates an occlusive chamber between the disc and the skin, making the chamber's conditions humid enough to hydrate and release the active ingredient, and to open the skin's pores to better absorb the active ingredient.

Developed by DBV Technologies (Boulogne Billancourt, France) the device system, Viaskin, for the cutaneous administration of proteins and peptides is based on a new technology: Diallertest Milk. The company presented Viaskin and its applications at the BIO Business Forum on May 8, 2007, in Boston (MA, USA).

Diallertest Milk uses this technology to diagnose cow's milk protein allergy and is suitable for everyday medical practice. Practical, simple to use, and painless as it is completely non-invasive, and it can be applied directly by the parents to the child's back at home. It significantly improves the effectiveness in the diagnosis of cow's milk protein allergy. DBV is also developing Diallertest to diagnose dust mite, soy, and wheat allergies.

The milk allergy test will soon be available in the United States. DBV Technologies and Numico, a Dutch company specializing in the production and sale of nutritional foodstuffs, have announced a distribution agreement for Diallertest Milk that will extend its original network to include the entire world. Today, about 70,000 tests have already been prescribed. The test is available in Australia, France, the Middle East, and New Zealand.
