Proficiency Test (PT) 2025 Parameters in Matrix Shipping Price

Allergen-PTs (qualitative / quantitative with z-scores and recovery rates) - Accredited Programs -

Principle of allergen PTs (ptAL01-10 + 12-13): Two Samples (25g each) with Allergens in a Food Matrix (Samples A + B), as pastry, chocolate dessert/ice cream or boiled sausage are provided for qualitative and quantitative determination. One of these samples contains the spiked or incurred allergen(s). The third "Spiking Level Sample" (Simple Matrix Sample SP) (15g) con- tains the same allergens in potato powder as a simple matrix without further processing with similar amounts (at the „spiking level“). The evaluation of results will be qualitative and quantitative. Quantitative statistics with z-scores will be done with the target values from the consensus values of partcipants' results (≥ 5 results) and from the known gravimetrically spiked values (every single result). So DLA calculates a recovery rate and recove- ry z-scores for every single quantitative result of the "positive"-sample and the "Spiking Level Sample". Any suitable method can be applied for analysis, in particular ELISA, LFD, PCR and LC-MS.

Proficiency Test (PT) 2025 Parameters in Matrix Shipping Price

Allergen-Screening (qualitative) NEW test of Action Levels included

ptALS1-3: 4 Samples (20g each) with Allergens in a simple Food Matrix (rice flour) are provided. All parameters are contained in 2 of 4 samples providing 2/3 and 1/6 of the new Action Levels (VITAL 4.0, 2024), respectively. The “action level” in mg/kg is calculated from the allergen protein reference dose per 100 g food portion. The positive detection of the 2/3 action level ensures that the action level can be detected safely even when the measurement uncertainty of the applied method is about 50%. While the 1/6 action level can proof the method performance at lower levels close to the LOQ. The evaluation of results is strictly qualitative with indication of the obtained agreements with the consensus values of the participants and the spiking of samples. All gravimetrically spiked quantitative levels are given in the reports. For analysis ELISA (+ Lateral Flow), PCR and LC/MS can be applied.

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 qual- itative (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. Multiple sets of results can be submitted for different methods. Please note: When different (extraction) methods are applied, further sample sets are required. Double sample material can be ordered.
