Medical science is advancing in leaps and bounds. New treatments, drugs and procedures are introduced regularly. One of the main areas of studies remains the development of new tests that will help physicians to diagnose diseases quicker. The earlier a condition is diagnosed the bigger the chance that it can be treated successfully. ELISA kits have done much to make the diagnosis of several conditions both easier and quicker.
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 presence of antigens or antibodies, or both, in the body is a clear sign of disease. This is because antigens are known as harmful substances. The body is able to detect the presence of antigens and it then immediately start producing antibodies to fight the antigens. It is therefore logical to assume that the presence of either substance indicates the presence of disease.
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.
Diagnosticians can get a lot of information form even the most basic EIA test. However, there are several versions or formats of the test and some are much more complex. The direct EIA, for example, requires that the antigen is screened with a multiwall coat. This makes it more difficult for the antibody to recognize the antigen. A result can only be obtained if the antibody is joined with a specific enzyme.
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.
Nobody will deny the fact that diseases are easier and cheaper to treat if they can be diagnosed at an early stage. Tests such as the EIA help doctors to do just this. Conditions such as HIV, pernicious anemia, syphilis, and many others have been diagnosed early enough to save the lives of the patient, all thanks to this amazing procedure.
