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.
