How ELISA Kits Help Specialists To Diagnose Diseases Quicker And More Efficiently

by Jocelyn Davidson

In the medical field, new medicines, treatment methods and procedures are introduced at such a dazzling pace that even medical experts struggle to stay up to date. In the field of diagnostics many advances have also been made. If a disease can be diagnosed during its early stages it is easier to treat and the chances of success are much better. <A href="http://www.elisatestkits.com">ELISA kits</A> have proven to be a major breakthrough. The enzyme linked immunosorbent assay enables diagnosticians to recognize certain conditions quickly.

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 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.

The sandwich EIA test requires the antibodies to be matched in pairs. The first one is covered with polystyrene and the role of the second antibody is to act as a detection agent. The main purpose of this test is to find out what the concentration of the analyte is. It is an extremely accurate test and can be used to diagnose latent diseases.

Any test or procedure that can help physicians to diagnose a disease at an earlier stage can help save lives. The EIA test certainly enables the accurate and early diagnosis of a variety of conditions. This can help ensure that treatment programs are less invasive and that the prognosis is better.
