The Best Discovery In Diagnosis; Elisa Test Kits

By Sally Delacruz


The new method in the field of diagnosis uses special tools that help find diseases and other foreign bodies in an easy way. This method involves an enzyme called immunoassay. Elisa test kits are also a key ingredient in this test. The whole test depends on color change as the main indicator of the existence or lack of existence of foreign bodies.

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.

The kits help a great deal in hastening research. A device that is not capable of delivering the sensitivity and the required reproducibility in long-term researches is normally not appropriate. Such equipment is, therefore, costly and unaffordable to the buyer. Those who wish to buy it should take utmost care while buying it; most of them are defective.

Besides antibodies, many other factors are crucial during the manufacture of these tools. For instance, rigorous antibody screening must be done, good standards chosen, steps for sample preparation developed and essays properly validated with the help of matrices. All these process are done with the purpose of attaining 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.

Usually, researchers take antigens from samples and attach them onto surfaces. They then apply specified antibodies with the intention of binding them with antigens. Special food substances are then applied. The reaction that follows gives a signal in the form of color change.

When the kits are used in carrying out the same test, the tools on the kit are dipped into a test tube of samples collected. The set-up is then washed and then incubated in chromogens. The kit itself is made up of rods with about twelve ogives that protrude. The process of washing and incubating normally occurs when the ogive is immersed in small wells made of micro-plates containing reagents.

This kit is compatible with different types of reagents. Because of this quality, simultaneous tests for different antigens can be carried out. For this to be possible, the Ogive is sensitized to react to different reagents. The sensitivity of the tools can also be improved through raising the amount of samples.

The capability of these kits to determine the number of antibodies in the body has made them to be widely applied in carrying out HIV and other tests where the number of antibodies is examined. They are also portable, unlike preceding technologies. However, not all of them are effective since some companies have compromised their qualities.
