What does ELISA stand for?

What does ELISA stand for?

• A. Enzyme-linked immunosorbent assay
• B. Enzyme-labile immunosorbent assay
• C. Enhanced lipemic immunoassay
• D. Endocrine laboratory immunoassay

Answer: (A)

ELISA stands for Enzyme-linked immunosorbent assay. The name reflects how the test works: an antibody or antigen is immobilized on a solid surface (the immunosorbent part), and an enzyme attached to a detection molecule produces a measurable signal, usually a color change, enabling detection and quantification. This plate-based immunoassay is widely used to detect various substances such as antibodies, antigens, hormones, and other proteins in samples. The other phrases don’t match the standard terminology used for this technique, so they aren’t the correct expansion of the acronym.
