Allergen-PTs
(qualitative / quantitative with z-scores and recovery rates) ptAL01 - 09: Two Samples (25g each) with Allergens in a Food Matrix, as pastry, chocolate ice cream or boiled sausage are provided for qualitative and quantitative determination. One of these samples contains the incurred allergen(s). The third "Spiking Level Sample" (15g) contains the same allergens in simple matrix without further processing with similar amounts. The evaluation of results will be qualitative and quantitative. For information DLA calculates a recovery rate and recovery z-scores 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 ptASW1-3: 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 an analytical test method, the Lateral-Flow-Test is particularly suitable. ELISA, PCR and LC/MS can also be used. |
