1. Allergens - Elicitors of Allergies and Intolerance Reactions |
|
|||
|
|
Allergen-PTs (qualitative / quantitative) - Accredited Programs - ptAL01 - 09: Two Samples with Allergens in a Food Matrix, as pastry, chocolate or wine, are provided for qualitative and quantitative determination. One of these samples and the "Spiking Level Sample" were prepared adding the allergenic ingredients. The "Spiking Level Sample" contains the allergens in a simple matrix in similar amounts. The evaluation of results will be qualitative and quantitative. For information DLA calculates a recovery rate for the "positive"-sample and the "Spiking Level Sample". Any suitable method can be applied for analysis. |

Allergen Swab Test (qualitative) - Wipe Test for Surfaces ptASW1-2: There are 2 samples of a Test Surface with Allergens offered for the detection of each allergen by means of a wipe test (swab test). The allergens to be tested were attached to one test surface, while the other test surface is "negative". The evaluation is exclusively qualitative (positive/negative) with indication of the obtained agreement with the consensus values of the participants and the spiking of the surfaces. As a analitical test method, the Lateral-Flow-Test is particularly suitable. ELISA, PCR and LC/MS can also be used. |
