What is the Elisa HIV test?
Elisa is an abbreviation for enzyme -bound immunosorbrant test . The Elisa HIV test is just one type of Elisa tests widely used in the scientific community. The Elisa HIV test was one of the original diagnostic tools used for HIV and AIDS. The ELISA test is a test used to determine whether there are antibodies or antigens in the body.
When performing the Elisa HIV test, a special image contains HIV antigens. The serum from the person who is undergoing a test is applied to the image. If a person is positive, their body fluids will contain antibodies for disease. These antibodies will be tied to antigens.
After this process, the slide is washed in a solution that removes everything except antigen and everything that is bound to antigen. Then an enzyme is applied to the slides, which creates a chemical reaction. The chemical reaction causes the sample to change colors if there are antibodies attached to the antigen. Therefore, the Change in the image of the image denotes the positive test of Elisa HIV.
Elisa is widely used for other types of diagnostics. The fact that this procedure can test not only antibodies, but also antigens, makes it a versatile instrument for scientists. Another use for ELISA test is the diagnostics of the West Nile virus.
Elisa tests are not controversial. While some types of testing are definitive, the ELISA tests that are used to screen drugs before employing are an example of a discussion surrounding Elisa. It is important that before testing the laboratory set numbers for what they consider to be a positive test and what they consider to be a negative test. This helps to reduce the number of false positives.
Even in its shortcomings, the Elisa test is a valuable diagnostic tool. It is so efficient and reliable that fast and accurate results are used in testing diseases transmitted by blood, allergy to food and the presence of drugs in the system. Alternatives to Elisa areOften more complicated and costly and obtaining accurate results takes longer. For these reasons, ELISA testing is widely used and accepted in the medical community.
