Guide to the Immunoassay Test
Immunoassay or it can also be called serology test is a chemical test carried out to identify and detect the concentration of certain substances in a sample, immunoassay test can be used to detect several things such as large proteins, or to determine and monitor the reaction of antigens and antibodies in the body. Immunoassay will perform an examination by taking a sample of human blood.
Immunoassays or serology tests are also widely used in the bioanalytic and pharmaceutical industries, such as conducting research, pharmaceutical analysis, discovery and development of new drugs, detection and diagnosis of viral, bacterial, fungal, parasitic, allergic diseases or infections and even some diseases such as cancer and SARS-CoV-2.
Immunoassay tests are considered to have test results that are more sensitive and specific in conducting examinations and monitoring of immunological reactions in the human body. This test can be qualitative or quantitative depending on the type and purpose of the diagnosis or sample to be investigated and detected.
Immunoassay Test Working Principle
Immunoassay works to bind and produce the body's antigen reaction as desired. There are two types of antibodies used in this test, namely monoclonal antibodies and polyclonal antibodies. Why should these two types of antibodies? Because these two types of antibodies are claimed to have a high affinity for antigen reactions.
Monoclonal antibodies can bind and produce a very specific antigen reaction, so that the output results obtained from the immunoassay test can be given more comprehensively. While polyclonal antibodies are the opposite of monoclonal antibodies. The use of these antibodies tends to give results that are not very accurate and less specific.
The working principle of an immunoassay designed to detect a specific analyte, such as influenza nucleoprotein, and the antibodies that have been carefully selected to ensure the detection of the analyte at low concentration with high specificity, meaning will not react with similar antigens. Immunoassay is designed too, to detect the binding of the specific antibody to the sample target analyte. Originally the signal from an immunoassay resulted from an enzyme acting on a substrate to yield a colored solution with the amount of color in the solution being equivalent to the amount of antigen in the test solution.
The Right Choice to Detect the SARS-CoV-2 Viral
Immunoassay tests have a higher level of accuracy than rapid tests, because their work methods are more sterile, safe, and automated-digital so that they can prevent and reduce contamination from exposure to other viruses. This is what makes the sensitivity level can reach a high percentage. Here are some other advantages when doing an immunoassay test:
- Has a high specification rate that reaches 99.81%.
- The possibility of cross-reaction between viruses or diseases is very rare or even small.
- Very effective for checking the SARS-CoV-2 viral, and other diseases such as cancer, rheumatism, hepatitis, or other infectious diseases.
- Has been recognized by Conformite Europeenne (CE), Food and Drug Administration Emergency Use Authorization (FDA EUA), to the NHS.
- The testing process is short but accurate (only takes +/- 5 hours.
