ELISA stands for

ELISA stands for

• A. Enzyme immunoassay
• B. Enzyme-linked immunosorbent assay
• C. Enzyme-linked immunoassay
• D. Enzyme colorimetric assay

Answer: (B)

The name ELISA is built from three parts that describe how the test works: the enzyme, the immune binding, and the solid-phase setup. It stands for enzyme-linked immunosorbent assay, meaning an enzyme is attached to an antibody or antigen and the reaction happens on a solid surface, like a microplate, to generate a detectable signal. The “linked” part highlights that the enzyme is attached to the immune component, and “immunosorbent” reflects the immune reactant being immobilized on a solid support. While you may see similar terms, the standard full form used in textbooks and labs is enzyme-linked immunosorbent assay. The other options either shorten away the immobilized, solid-phase aspect or focus on a different detection description (colorimetric) rather than the immunologic and solid-phase nature of the test.
