Food manufacturers typically utilize ELISA-based test system to detect specific proteins in food. There are also a number of PCR methods that are utilized for DNA detection. Eurofins was the first laboratory to offer an additional test to analyse multiple allergens at the same time via the LC-MS/MS method.
