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

Preparations come in different many forms. All these forms are designed to work in a particular similar manner. This implies hat the principle of operation is one for the many kinds. The only thing that varies is the approaches applied from case to case. Some of the differences include preparation types as either direct or indirect. Direct preparations searches for antibodies in the sample; indirect preparations seek to identify antigens in the sample of interest.

Another variation is observed in the number of antibodies and antigens involved in the test procedure. Other than single antigen single antibody formulation, there is another one termed as sandwich Elisa. It comprises two different antibodies meant to test the antigens trapped between two antibody layers.

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: Several firms engage I production as well as distribution of the test kits. This is both carried out within national boundaries and internationally. The most important thing to consider here is quality and reliability of supplies. They could be prepared in the form of competitive assays or immunometrics. The information leading to purchase and possession of quality test tools is easily obtained online. In fact, one can buy these products online.

These preparations are availed in either immunometric or even competitive assays.In all their operations, special considerations must be given to desirable accuracy, sensitivity and specificity level. These are some of the components which define a good test tool. It is the best way of ensuring success in diagnosis and research.

Merits of using the test kits: These kits are generally accurate and fast when compared to other available means of diagnosis. They are equally very simple and so easy to use. All tests of this form are cheaper in terms of financial costs involved and finally, they can detect both antibodies and antigens.

Conclusion: Of all the diagnostic tools, these test kits form the best option for all tests that can be done using them. They make life simple and grant both the care givers, researches and clients a breathing space. It is therefore recommended that this be the first choice as an alternative to other complex expensive options. Better still, there are several preparations which therefore offer a client a wide range of choices to make.
