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.
Also known as enzyme immunoassay, or EIA for short, this laboratory technique is used to measure the concentration of antibodies or antigens in a solution, normally a blood sample. The ability to determine these concentrations is extremely important in the diagnostic process. Among the main advantages of this technique, when compared with others, is that it is very easy to carry out and a large number of tests can be processed simultaneously.
The ability to identify the presence of either antibodies or antigens in the body is very important. This is because antigens are known to be harmful substances. As soon as the body recognizes the presence of antigens, it starts to produce antibodies to neutralize the harmful antigens. When either of these agents is present in a sample, the existence of a disease can be deduced logically.
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.
