PBCMedicals: Best Rapid Covid-19 Test Kits
Different Type Of Covid-19 Test Kits
Rapid Antigen Test Kits
Antigens are molecules capable of stimulating an immune response. Each antigen has distinct surface characteristics, or epitopes, that result in specific responses.
An antigen test, often referred to as a rapid or rapid COVID-19 test, is a viral test, one of two types of tests used to detect COVID-19. Rapid antigen tests are considered one of the simplest and fastest ways to get tested for COVID-19 and have been recommended by many authorities and governments as a cost-effective way to mass test populations.
How do antigen tests identify COVID-19?
Rapid antigen tests identify protein fragments on the surface of the coronavirus to identify the presence of the pathogen among the people performing the test2. Samples are taken from subjects rubbing inside the nose or mouth.
How The Rapid Antigen Test Kits Work?
A sterile swab is inserted into the patient's nostril to the surface of the posterior nasopharynx. The swab is turned three or four times and removed from the nasal cavity.
The swab is placed in an extraction buffer tube. While the protective tube is squeezed, the swab is shaken at least five times.
When the swab is removed, the sides of the tube are squeezed to remove the liquid from the swab, and then the nozzle cap is firmly pressed against the tube.
Three drops of the extracted sample are added to the sample well of the test device. Now you can wait for the test results.
The test result is ready to be read after 15 minutes. It should not be read after 30 minutes, as this can lead to false results. The test is positive if a colored line appears in the top section (C) and bottom section (T) of the results window.
The presence of any test line, however tenuous, together with a control line, should be considered as a positive result.
Test results can help health care professionals make appropriate decisions quickly.
For diagnostic purposes, results should always be evaluated along with the patient's medical history, clinical examination, and other findings.
Now Let’s Talk About Our Second Covid-19 Test Kit Which Is Antibody Test Kit
Antibody Test Kits
Antibodies (immunoglobulins) are Y-shaped proteins produced by the B cells of the immune system in response to exposure to antigens. Each antibody contains a paratope that recognizes a specific epitope in an antigen, acting as a lock-and-key binding mechanism. This binding helps remove antigens from the body, either by direct neutralization or by "labeling" other arms of the immune system.
What Is an Antibody test?
An antibody test reveals whether a person has already been exposed to an infection, by detecting antibodies in their blood or serum. This can be done using a laboratory test such as ELISA (enzyme-linked immunosorbent assay) or CIA (chemiluminescent immunoassay)
Antibody tests are usually not used to diagnose a current infection, as it takes some time for the body to produce antibodies. During the period prior to activation of the adaptive immune system, the rapid-acting, non-specific innate immune response fights infection. A negative test result can occur if the test is done too soon after infection before the body has produced antibodies. False-positive test results could also occur due to cross-reactivity.
Antibody testing is useful to help track the spread of a disease, identify those who should be prioritized for vaccines, and highlight potential donors for convalescent plasma therapy.
How Does An Antibody Test Work?
You will have to do the test at home.
You will receive the test kit in the mail. Read the test kit instructions carefully.
You will need to prick your fingertip with a device called a lancet and squeeze some blood into a tube.
You can ask someone to help you if you are nervous about doing the test, unless you are self-isolating.
Send the sample to the lab.
Conclusion:
The antigens activate your immune system to launch an antibody response. Specific antibodies detect specific antigens. This means that each antibody wages a war against a target antigen. Once antibodies detect antigens, they bind and neutralize them.
This knowledge is stored in the long-term memory of your immune system. He fights the antigen in case he tries to attack his body again.
