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.
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.
When there are antibodies present in a blood sample it means that the body has produced them to counteract the effects of a harmful substance, called antigens. If there are antibodies present, it is certain that there are also antigens because the antibodies are only produced when a threat is detected. By identifying the specific type of antibody produced by the body it is also possible to determine the exact nature of the threat.
The administration of the test is quick and painless. All that is required from the patient is a small blood sample. The sample is taken to a laboratory where it is added to a series of petri dishes that were prepared with different antigens. The antibodies can be identified when they react to specific antigens. The further reactions between the two agents are then studied by adding enzymes.
There are different forms of the EIA test, ranging from very simple to extremely complex. Different kits are used for the different forms of the test. With the direct EIA test, for example, the antigen is first covered with a multiwall plate. In this case the antibody in the blood sample will only react with the antigen if specific enzymes are added.
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.
One of the most accurate tests is called the sandwich EIA test. In this test matched pairs of antibodies are utilized. One of the antibodies is coated with polystyrene and the other one is used as an agent for detection. One of the main advantages of this form of the test is that the concentration of analytes can be determined accurately. This can help in diagnosing latent diseases that cannot easily be done with other tests.
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.
