Examples

  • At each stage, they checked for a Bt protein—a type known as CRY1Ab—using an antibody-based test known as ELISA, short for enzyme-linked immunosorbent assay.

    Academic text (2002)

  • After collecting the samples, they performed an enzyme-linked immunosorbent serologic assay to analyze the immune response.

  • An indirect enzyme-linked immunosorbent assay (IEA) allows an early diagnosis.

  • Blood samples were tested for antibodies to SNV, using enzyme-linked immunosorbent assays (ELISA; Feldmann et al. 1993).

    Academic text (2002)

  • An enzyme-linked immunosorbent assay (ELISA) that detects soluble Beta/A4 in plasma and CSF could also prove useful.

Morphology

enzyme-linked + immunosorbent + serologic + assay

Although the phrase is built from semantically meaningful technical parts (enzyme-linked = attached to an enzyme; immunosorbent = binds antibodies/antigens; serologic = relating to serum; assay = test), the combination refers to a specific laboratory technique (ELISA) and requires domain knowledge of immunology and lab methods that a B1 learner would not have. The overall procedural and diagnostic meaning is therefore not predictable from the constituents for an average B1 learner.

Etymology

Enzyme-linked immunosorbent serologic assay describes how the 'test' works: immunosorbent means the sample is 'soaked up' on a plate to hold immune proteins, enzyme-linked means an enzyme is attached like a color tag, and assay means 'test'. So the name explains it is a 'test' that uses an enzyme tag and a surface that catches 'antibodies' so we can see if they are present.
