Accuracy And Sensitivity Is Attainable Using Elisa Test Kits

By Sally Delacruz


There has been invented a new method of detecting antigens and other unwanted materials in a liquid or wet sample. Researchers usually look at color change within the samples to decipher whether foreign substances exist in the sample or not. A solid-phase enzyme, immunoassay, and the Elisa test kits are the main components of this test.

The main aim for the manufacture of these tools is to foster consistency and accuracy of the results obtained. It is therefore important for them to be easy to follow, precise, sensitive and target certain types of foreign materials in the body. The kits should therefore go through serious testing with different types of samples.

Accuracy is very important in making tests using these devices. They are, hence, calibrated to promote good vision which then translates into accuracy. Once calibration is properly done, the device will acquire sensitivity to the reagents used. Other factors observed in deciding on the best apparatus to use include; dynamism, ability to measure a wide range of readings, precision, and the ability to recover earlier readings.

These kits help in making research faster. A device that is deficient of the ability to reproduce results and sensitivity in making readings during research is not the best for Elisa test. Researchers might end up using a lot of money and time as a result of using these apparatus. This means that one needs to take a lot of caution while buying them from any company.

In manufacturing these tools, many other things, on top of antibodies, are needed. The researcher needs to screen a lot of antibodies, appropriately select standards, come up with effective steps of preparing samples and validate essays using appropriate matrices. All these need to be done for effectiveness.

These instruments can detect minute organisms found in small amounts. Detecting them is vital since it helps discover many diseases before they fully develop into serious illnesses. Over time, this method has always been used in diagnosing diseases in both plants and animals. It can also be applied in fostering quality in industries.

The testing process involves attaching samples onto surfaces and later binding the antigens in samples with antibodies. Specific food substrates are then added. Color change seen in the ensuing reaction is the indicator of the absence or presence antigens.

Whenever multiple Elisa tests are done simultaneously, the devices are immersed in a container of samples collected by the researchers. What follows is washing and incubation. The rods in these kits have approximately 12 ogives. The process of washing and incubating usually takes place after immersing the ogive into micro-wells containing reagents.

Different reagents can be used with these kits. This means, it is also possible to simultaneously detect a variety of antibodies and antigens. This is normally done through sensitizing the ogive to react towards many reagents. It is also possible to increase the volume of the sample for the sake of improving the sensitivity of the test both in clinical and environmental samples.

The fact that these facilities can be used in establishing the amount of antibodies in the human body has made it possible for the test to be used in HIV testing. Their portability is also a cause for their popularity in carrying out such tests. Nevertheless, caution should be taken in determining the best kits.
