Diagnostic Test ELISA Kits For Quality Outcome

By Lila Bryant


Enzyme linked immunosorbent assay is an old technique used in diagnosis of various health conditions. It is an improvement of an old and relatively similar diagnostic c tool called enzyme immunoassay. These diagnostic tools both use preparations of antibodies to detect given antigens in the sample of interest. These tools are designed in the form of kits and hence the name ELISA Kits

Types of test apparatuses: Much effort has been applied and there are many forms of preparations available. They range to higher values as high as 138000. However, all of the many existing kinds operate in a more similar manner with some little variations. The first most notable variation is the existence of direct and indirect types of tests. Direct tests are designed to examine for antibodies while indirect formulations are meant to examine for antigens as the kits can work in either way.

A second variation or difference is what is termed as sandwich Elisa. This preparation is used in the measurement of antigens entrapped between two layers of antibodies. This far there are up to 138000 different kinds of test kits available on demand.

Uses of these products: These tests are very useful as they aid detection of antigens or antibodies present in a sample being evaluated. It can therefore be necessary to apply these tests in improving the quality of outcomes in areas as; determination of serum antibody concentrations, home pregnancy test and the food industry operations. This kind of test has widely been adopted and applied in fields such as immunology, biology, and biological pharmacy among many more.

Sources of the test kits: There are a number of firms that are directly involved in the preparation and or distribution of test kits. All clients engaged in some form of health care or scientific researches can highly benefit from their services. The preparations come in either immunometric or competitive assays. One must take time to asses and closely examine test kits as not all are prepared in the right and desired quality.

While organizing or preparing for the purchase, close interest must be given to quality. This means that such aspects as precision, sensitivity and specificity must be reviewed and evaluated before choices are made. It forms one of the tested and proven ways of ascertaining quality.

Advantages of using the test kits: One main advantage of these kinds of test is that they are accurate and fast. This implies that time needed to arrive at desired outcome is minimal and hence very convenient in time bound or time limited undertakings. Secondly, the kits are very easy to use. This usually involves simple procedure that involves application of a sample to the kit and waiting for results within minutes. On a similar note, tests of this nature are relatively cheap to carry out and needs simple interpretation. Finally, it is equally of merit that these kits can be used for both determination of the presence of antigens

Summary and conclusion: Among the other simple or sophisticated tools of diagnosis, kits of this kind form the best option for all persons. This kind of tests make like simple as doing them is less involving to both the client and service provider. For this reason, it therefore necessary that individuals opt to use available test of this kind unless advised otherwise
