ELISA tests

What is an ELISA test?

Enzyme-Linked Immunosorbent Assays (ELISAs) are the most widely used type of assay. They have evolved from viral lysate tests to tests containing recombinant protein and synthetic peptide antigens:

  • They have high sensitivity and specificity.
  • ELISAs are designed specifically for screening large numbers of specimens at a time, making them suitable for use in surveillance and centralized blood transfusion services.
  • As ELISAs require sophisticated equipment and skilled technicians to perform the tests, their use is limited to certain circumstances.
