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.
This revolutionary technique, also known as EIA, or enzyme immunoassay, is conducted in a laboratory. It is used to determine the concentration of antigens or antibodies in a specific sample. The presence and concentration of antibodies is an important indication of the presence of a variety of medical conditions. The test is extremely popular because it is easy to do and many different tests can be processed at the same time.
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.
There is no need to stress about this type of test. Patients are required to provide a small blood sample. This sample is then added to a petri dish that contains antigens typical to the condition for which the patient is tested. If the blood sample combines with the antigen, antibodies are present and this confirms the diagnosis. The amount of antibodies is determined by carefully adding enzymes to 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.
The indirect IEA test is another example of how this protocol can be used in an advanced manner. In this instance the antigen is actually covered by a polystyrene plate. This forces the antibodies to go through two distinct stages before the antigen is detected. This test allows technicians to identify both primary and secondary antibodies. This is valuable because it may eliminate the need for further expensive tests.
In the case of yet another type of EIA test, the sandwich test, pairs of antibodies are tested. The first antibody is covered with a polystyrene plate. The next antibody is then added in order to determine the concentration of the analyte. This is a complicated procedure but it is extremely accurate and flexible.
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.
