| Anmerkungen | Allergen-PTs (qualitative / quantitative) - Accredited Programs - The PROCESS of PT rounds ptAL01 - 09 + 13: Two Samples (25g each) with the Allergens in a Food Matrix (Samples A + B), as cheese, pastry, cocoa spread or boiled sausage are provided for qualitative and quantitative determination. One of these samples contains the spiked or incurred allergen(s). Incurred allergens were added at the same time as the other food matrix ingredients and processed in the matrix (e.g. baked or cooked). The third sample, the "Spiking Level Sample" (Sample SP) (15g) contains the same allergens in potato powder, a simple matrix without interfering compounds and without further processing in 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. Recovery rates and recovery z-scores are calculated for every single quantitative result of the "positive"-samples and the "Spiking Level Samples", regardless which method was applied. By comparing the recovery rates in tabular form, the influence of the food matrix and processing on the performance of the analytical method can be directly seen. Any suitable method can be applied for analysis, in particular ELISA, LFD, PCR and LC-MS | ||||||
