Immunoassays, with the specificity and sensitivity, the relative simplicity andlow-cost, are suitable for routine analysis and screening for large amounts offoodstuffs. A fundenmental problem in immunoassay, however, is that the complexand variable chemical components such as proteins, lipids, carbohydrates and smallmolecules in food samples might greatly interfere with the immunological reactions.The matrix effect is considered a task for further development and application ofimmunoassay of foodstuffs.
