The Unique Design of T.R.U.E. TEST

T.R.U.E. TEST Design

1Laminated Foil Outer Packaging:

Airtight and opaque, to protect the test from light and moisture.

2Thin Protective Plastic Cover:

Protects patches from physical damage during storage and opening of the outer foil.

3Allergen-Impregnated Vehicle:

Each allergen is incorporated into a hydrophilic gel that is dried into a thin film. When applied to the skin, this film becomes hydrated by skin moisture and the allergen is released.

4Adhesive Tape:

Each patch is attached to a non-woven, occlusive and hypoallergenic surgical tape.

5Occlusive Plastic Backing:

The impermeable, flexible backing assures optimal contact between the skin and the allergen(s) and promotes maximum penetration.
