ELISA or EIA stands for?

Explanation:
ELISA stands for Enzyme linked immunosorbent assay. This is a plate-based test that uses antibodies to detect a specific target, with an enzyme attached to the detection molecule to create a measurable signal. The immuno part comes from the antibody-antigen interaction, the linked part means the enzyme is chemically attached to an antibody (or antigen) so its activity can be turned into a detectable readout, and the assay part indicates this is a test used to measure how much of the target is present. In a typical ELISA, the target is captured on a solid surface, a binding partner is added, and then an enzyme-labeled detector is introduced. A substrate is added, and the enzyme converts it to a color (or another signal) that you can measure to quantify the amount of target. There are various formats (direct, indirect, sandwich, competitive), but they all rely on the same principle. The standard expansion to remember is Enzyme linked immunosorbent assay.
