The Enzyme-linked immunosorbent assay (ELISA) is designed to detect the presence of an antigen or antibody in a sample. It uses a known weakly positive serum on the same plate as the patient sample to compare and measure the relative amount of signal generated by the patient's serum, making it a quantitative test. The results are typically reported as the optical density (OD) value, which is proportional to the concentration of the antigen or antibody in the sample.
