In the most simple form of an elisa, antigens from the sample to be tested are attached to a surface. Elisa is a laboratory technique that detects certain antibodies, antigens and other substances in your blood, pee or other bodily fluid Laboratory scientists use this technique for several medical tests — from diagnosing infections to confirming pregnancy. What does elisa detect and measure An elisa is an indirect measure of the binding of antibody with antigen The quality of the assay will depend in large part on the specificity of the antibody for the antigen
If the specificity is poor, there will be a highly nonspecific background. Elisa tests can detect hormones, bacterial antigens, and antibodies Read on to learn how the elisa test works and how it's used. It is a commonly used laboratory test to detect antibodies in the blood An antibody is a protein produced by the body's immune system when it detects foreign or potentially harmful substances, called antigens.
