Elisa tests, also known as enzyme-linked immunosorbent assays, are commonly used in laboratories to detect the presence of specific antibodies or antigens in a sample. There are several other terms used to describe elisa tests, including EIA (enzyme immunoassay), immunoassay, and enzyme assay. These tests are essential in diagnosing various diseases, including HIV, Lyme disease, and other infections. The accuracy and sensitivity of elisa tests are crucial for prompt and effective treatment of diseases. The continuous development and improvement of elisa tests have contributed significantly to the advancement of medical science and have played a pivotal role in the control and eradication of epidemics.
