The β-lactam Rapid test is based on the specific immune-chemical reactions between antigen and antibody. It relies on the competition between β-lactam residues in the sample and β-lactam immobilized on the T line on the membrane for the β-lactam antibody-dye conjugate. Since the drug is present in the sample, it will compete with the drug immobilized on the T line for the limited amount of dye-antibody. When sufficient amount of drug is present in the sample, it will saturate the antibody. Consequently, it will show an extremely light or even invisible T line, indicating a positive result. On the other hand, a negative sample (or when the drug is lower than the minimum detectable concentration, 2 ppb) will generate two visible lines in both the T and C line sections.
