Even medical experts find it difficult to keep pace with the rapid advances that are made in the various medical fields. The development of diagnostic tests and procedures receive a lot of attention. This is because the prognosis is just so much better if a disease can be diagnosed early. The treatment is less invasive and the chances of success are much higher. ELISA kits have proven to be an efficient, economic and quick way in which to diagnose a wide variety of conditions.
This test, also known as EIA is a laboratory procedure that is used to measure just how much antibodies and antigens there are in a specific sample of blood. The ability to measure the concentration of antigens and antibodies is a vital part of the diagnostic process. As an added bonus, this test is very easy to administer and many tests can be processed simultaneously.
When there are antibodies present in a blood sample it means that the body has produced them to counteract the effects of a harmful substance, called antigens. If there are antibodies present, it is certain that there are also antigens because the antibodies are only produced when a threat is detected. By identifying the specific type of antibody produced by the body it is also possible to determine the exact nature of the threat.
Patients do not experience any form of discomfort during the test. A small sample of blood is removed and then sent to the laboratory. There, a technician will add the sample to a petri dish that is already prepared with antigens. When the antibodies in the blood sample bind with the specific antigen in the petri dish and identification can be made. Further enzymes are then added to see how the antibody and the antigen react to each other.
There are different forms of the EIA test, ranging from very simple to extremely complex. Different kits are used for the different forms of the test. With the direct EIA test, for example, the antigen is first covered with a multiwall plate. In this case the antibody in the blood sample will only react with the antigen if specific enzymes are added.
The indirect EIA test saves time and money because it is able to identify both secondary and primary antibodies during the same test cycle. Savings are achieved because the test often negates the need for other tests. In this case the antigens are coated with polystyrene and they can only be detected by the antibodies after two carefully manages stages.
The sandwich EIA test requires the antibodies to be matched in pairs. The first one is covered with polystyrene and the role of the second antibody is to act as a detection agent. The main purpose of this test is to find out what the concentration of the analyte is. It is an extremely accurate test and can be used to diagnose latent diseases.
Any test or procedure that can help physicians to diagnose a disease at an earlier stage can help save lives. The EIA test certainly enables the accurate and early diagnosis of a variety of conditions. This can help ensure that treatment programs are less invasive and that the prognosis is better.
