The ELISA method is a test which is used in immunology and other scientific fields to detect antibodies and antigens. ELISA stands for Enzyme-Linked Immune Sorbent Assay, which refers to the fact that antibodies coupled to enzymes are used to determine the results of the test.
The ELISA method is used in: (Application)
- Medicine as a diagnostic tool (to test a blood sample for HIV), and also in plant pathology
- Quality control in many industries, particularly in the food industry, where it can be used to determine whether or not a particular product contains food allergens like peanuts and dairy products
- Testing drug use, both recreational drug residue, and performance enhancing drugs use.
