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.
Application of these products: Detecting antibodies or antigens is a significant step in health care or health research. This forms the main ground on upon which test sets like the ones being discussed here are used for. Such tests isolate the antigens and or antibodies of interest in time and thereby contribute to the overall success. Immunology, food producing industries and biological pharmacies are but a few examples of the direct application of this kind of examinations. For instance, in food industries, the test is used to asses for the presence of food allergens which may not be safe to consume.
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.
In so doing; keen interest must be given to high precision, desirable accuracy, sensitivity, and acceptable specificity levels. This is the only sure way of distinguishing committed partners in production from mere money making firms.
Benefits of using the test kits: There are a number of advantages in using these test kits. The overriding advantage is that they are accurate and fast. This makes them very reliable and reassuring at the same time. Secondly, these kits are easy to use. They do not involve a lot of technical evaluation interpretation to obtain the needed results. Thirdly, tests of this kind are often cheap as no huge financial expenses are generally incurred by the client. Lastly, there is an added advantage that the tests can detect both antigens and antibodies as the need may be.
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.
