The microplate has become a standard tool in analytical research and clinical diagnostic testing laboratories.
[28] [29] ELISA can also be used in toxicology as a rapid presumptive screen for certain classes of drugs. Enzyme-linked immunosorbent assay plate. The ELISA was the first screening test widely used for HIV because of its high sensitivity.
