(see bottom of page)

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) contains 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 recovery 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.

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 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. 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.

Single Proficiency Test (SPT) Program of all DLA Allergen Response PTs and Action Level PTs
These SPTs are especially suitable for method validation and verification!

By means of a Single Proficiency Test it is possible to participate individually and flexibly at any time, even outside the regular PT program, in a proficiency test format for a single participant laboratory. The target values (assigned values) of the SPT test material are determined on the basis of known reference values from previous PTs / inter laboratory tests, contents of spiked analytes (reference standard) or by reference laboratories.

Allergen-Response SPT of processed allergenic Ingredients

sptALR1-10: 5 Samples (20g each) of a differently processed Allergen are provided for qualitative and quantitative determination, a simple Carrier Matrix as well as a „Blank Sample“ (Carrier Matrix). The individual processed ingredients of the samples are mixed gravimetrically by DLA each from 4 industrially manufactured products. The analytical methods are optional.

All available results (from DNA-based as well as protein-based methods) should be considered to assess whether the final decision for the samples is “vegan compliant” or not (animal ingredients < 0,1% or > 0,1%).

Additionally, a qualitative evaluation is done for all available parameters separately for the following groups of methods: protein-based methods (e.g. ELISA, IEF, MALDI-TOF) and DNA-based methods (e.g. PCR-techniques, NGS, Microarrays).
