Accuracy And Sensitivity Is Attainable Using 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.

These kits are always made with the purpose of providing accuracy and consistency in research results. They are therefore required to be sensitive, easy to follow, precise and specific to individual tests. This can be easily achieved through rigorous testing. The testing may involve validating with many samples from, serum, saliva, feces and urine.

The kits are usually calibrated to enhance visibility, and, hence, accuracy in taking measurements. Calibration also provides the sensitivity required in reacting to the reagents. Good instruments must also satisfy users in terms of quality specifications. They must, in addition to this, foster dynamism in measurements, precision, and recovery, and should be consistent in giving 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.

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.

The kits have the ability to detect lowly concentrated foreign elements with the objective of diagnosing and eliminating certain germs while still developing. It has always been possible to use them on plants, human beings and other human beings. Quality control within industries can also be achieved through using them.

This process involves putting antigens onto a surface, and then applying specific antibodies onto them. Specific substrates are then added to this combination of antibodies and antigens. Results are always in form of color change.

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.

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 ability of these testing tools to establish the quantity of antibodies has been applied in testing for HIV and other immune deficiency related diseases. When few antibodies are observed in the body, then the victim is declared HIV positive. The fact that they are portable also contributes heavily towards making Elisa kits popular. Care has to be taken while buying them; most manufacturers do not pay attention to quality.
