The Working Of Cardiac Elisa Kits

By Sally Delacruz


Technological advancement in medicine has helped come up with better diagnostic methods. The cardiac Elisa kits are the latest invention in this field. They are enzyme-dependent test devices that help in determining the presence or absence of heart diseases. These equipments are capable of discerning problems in hearts of virtually all animals.

This process depends is an enzyme dependent process that uses color change as an indicator of reactions in reagents. The process works through an enzyme immunoassay which combines with antigens producing the subsequent color change. This test is capable of establishing the presence of both antibodies and antigens.

This test can also be used in detecting foreign bodies that exist in low concentrations. Heart problems can, therefore, be identified before they become chronic. The patient is advantaged; he will spend less money fighting a developing problem than he would have spent on a chronic one. This is because it is cheaper treating a disease while still in its early stages than when it has developed into a complex illness.

Proper working of this equipment means it is sensitive to reactions, gives accurate results, and is capable of making many detailed readings at a time. When a tool is sensitive, it can exhibit any slight change resulting from the reaction between samples and reagents. Its accuracy ensures that results obtained are free of errors, and hence, believable. They are also manufactured to work on specific problems.

It is also important that the instruments are made in a way that makes them stable. To attain stability, one must cut down on the rate loss of these activities. This is possible through proper storage. Stability can also be achieved through minimizing the effects of the surrounding on the set-up. This means temperature, humidity and pressure have to agree with the standard lab requirements. There should be somebody to control incubator temperatures. If only one person is allowed to work on the research from beginning to end, it will be easy to achieve stability.

For proper working of this activity, the researcher must ensure that all standards, reagents and samples are prepared in advance. The next thing is addition of some samples to all the wells and incubating them for close to 2 hours. He should then aspire and add some reagents. Next, he should put it back in the incubator for an hour, and later aspire and wash the mixture three times. The substrate solution should then be added, and the mixture incubated for a period of between 20 and 25 minutes. After, this step, a stopping agent must be added to stop the reaction for the researcher to make readings.

The main principle applied here is enzyme sandwich. The plates inside the testing equipment are always coated with antibodies for specific heart defects. Samples are put into the plates in an appropriate manner. The main contents of the samples are specific biotin-conjugate antibodies. Before incubating, a conjugate of Avidin is added to all plates.

After the addition of substrate solutions, it is only the wells that will contain type 3 of Tropin I. The reagents will then show a change in color. The reaction is brought to an end by adding a solution of sulphuric acid, and the change in color is measured is a special style.
