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.
The EIA test, as it is also known, is used to analyze a sample of blood in order to determine the concentration of antibodies and antigens. It would be very difficult to make an accurate diagnosis if the concentration of the antigens and antibodies cannot be determined. Doctors favor this test because it is relatively easy to perform and the results are available quickly.
Antibodies are protein substances that are produced by the body when it detects the presence of dangerous substances. The dangerous substances are called antigens. When antibodies are detected by means of the EIA test, it follows logically that there must be antigens too. The exact identity of the antigens can be determined by identifying the type of antibody in the sample. In this way a diagnosis can be made confidently.
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 variations of the EIA test but the more complex tests provide much more accurate results. Each type of test requires a different kit. The direct EIA test, for example is straightforward and results are available very quickly. In this case the antigens are coated with multiwall plates and the antibody can only react with the antigen once it has been conjugated with enzymes.
With the indirect EIA test polystyrene plate is used to cover the antigen. This allows the technician to process the test in two distinct stages before the antibody will be able to identify the antigen and react with it. During each stage it is possible to identify both primary and secondary antibodies. The benefit of this ability is that it saves money and time.
Matched pairs of antibodies are used in the processing of the sandwich EIA test. In this case one of the antibodies is coated with polystyrene while the second one acts as a detecting agent. This test is performed when it is deemed necessary to determine the concentration of analytes in the sample. It is extremely accurate and can even detect diseases that have not manifested yet.
The EIA test is so popular with medical experts because it is versatile, quick and very accurate. The test is easy to administer and to process too. Patients benefit because their conditions can be diagnoses at an earlier stage. This makes treatment easier and it improves the prognosis.
