Medical science advances at an astonishing pace on all fronts. The area of diagnostics is one particular field where great efforts are made to devise tests and procedures that can help doctors to diagnose diseases quicker and more accurately. This is important because successful treatment often depends upon an early diagnosis. ELISA kits, for example, have empowered doctors to efficiently detect a wide range of diseases.
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.
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.
Then there is the indirect EIA test. In this case the antigen is covered with a polystyrene plate that can only be detected in two distinct stages. The main advantage of this format of the test is that it offers increased sensitivity. Both primary and secondary antibodies can be identified. This entails cost savings and it may even eliminate the need for further 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.
Nobody will deny the fact that one of the most important components of medical treatment is the ability to diagnose diseases. The earlier it is done the easier it is to treat and the better the prognosis will be. EIA offers hope to patients and it enables physicians to offer better chances.
