One cannot help but to stand in awe of the rapid progress made in the medical field. New techniques and medicines are introduced at an astonishing rate. Of course, one of the main fields of research is diagnostics. No one will argue the fact that an early diagnosis ensures a better prognosis and lower treatment costs. ELISA kits, an enzyme linked immunosorbent assay, allow doctors to diagnose a variety of conditions quickly and efficiently.
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.
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 experience no pain when the test is administered. A small quantity of blood is taken and then sent to a laboratory where a technician has already prepared a number of petri dishes, each containing a different antigen. The blood sample is then added to the dishes. If the antibodies in the blood samples react to any of the antigens they can be identified.
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.
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.
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.
