One of the most important fields of study in medical science is to develop new and improved ways in which to diagnose diseases. The earlier a disease can be diagnosed, the easier it is to treat. Early diagnosis also improves the prognosis. This is why so many scientists concentrate upon the development of new and more efficient tests. One such test that has proven to be invaluable is the enzyme linked immunosorbent assay. With ELISA kits doctors can now diagnose various conditions easily and efficiently.
EIA, as this technique is also known, is an extremely popular test. This is because it is so easy to carry out and as an added bonus large numbers of tests can be done at the same time. The purpose of the test is to find out what concentration of antigens or antibodies exists in a specific sample. Antigen and antibody concentrations are very important indicators in the diagnostic process.
The importance of being able to detect the presence of antibodies or antigens cannot be overemphasized. Antibodies are proteins that the body produces when a harmful substance in the body is detected. These harmful substances are called antigens. By being able to identify the type of antibody produced by the body, physicians can accurately determine the type of harmful antigens that triggered the production of the antibodies.
Patients need not fear this simple test. It only entails the drawing of a small blood sample. This sample is then added to specific antigens in a petri dish. If there is a reaction between the blood sample and the antigen, then the presence of antibodies is confirmed. In fact, the antibodies will combine with the antigens. By adding enzymes it is possible to determine the amount of the antibodies in the sample.
A lot of information can be gained from an EIA test. This is true even when the simplest form of the test is used. Yet it is possible to administer more complex tests, such as the direct EIA test. In this case a multiwall coats the antigen. This makes it difficult for the antibody to recognize the antigen. Recognition only takes place when very specific enzymes are introduced.
Another important variant of EIA is the indirect test. In this case two stages are engineered by covering the antigens in polystyrene plates. This is done to achieve increased sensitivity. Antibodies are introduced in primary and secondary stages. The test can produce multiple results which means that is saves cost and time. In many cases this test, which is more elaborate, eliminate the need for more tests.
The sandwich EIA test needs pairs of antibodies that are matched in pairs. The first antibody is coated with polystyrene. A second antibody then serves as the detection agent. The purpose of this test is to determine the concentration of the analyte. This test is extremely useful in the diagnosis of latent diseases and it is deemed to be highly accurate.
When all is said and done it is still the early diagnosis of a disease that provides the best chance of recovery and successful treatment. That is why tests such as EIA are so important. They allow doctors to identify the potential or existence of disease at an early stage. This gives the patient a better chance.
