Did you mean Enzyme-Linked Immunosorbent Assay?

GlossaryEnzyme-Linked Immunosorbent Assay

laboratory test detecting specific proteins using antibodies and enzymes

Enzyme-Linked Immunosorbent Assay (ELISA) is a laboratory technique used to detect and measure specific proteins, antibodies, or hormones in a sample. It works by using antibodies linked to an enzyme that produces a detectable signal, usually a color change, indicating the presence and quantity of the target substance.
