The Rapid test aims to determine who people are likely to be infected and have the potential to spread the Corona virus. Get to know more about the types, implementation procedures, and uses of rapid tests for the Corona virus in the following article

  • Rapid Antibody Test
  • Antigen Swab (Rapid Test Antigen)
  • PCR

Rapid test is one of the methods used to detect COVID-19 infection in the human body. The rapid test examination is only an initial screening. Furthermore, the results of the examination must still be confirmed through PCR examination.

Rapid test is generally used as a requirement for those who will use public transportation such as trains and planes, especially for those who have not completed the COVID-19 vaccination.

Type of Rapid Test ?

There are two types of corona rapid tests that are commonly used, namely:

1. Rapid antibody test

At the beginning of the pandemic, the rapid test that was widely used as a screening method was the antibody rapid test. This test is useful for detecting IgM and IgG antibodies. These antibodies will be formed by the body when there is exposure to the Corona virus.

In other words, if these antibodies are detected in a person's body, it means that the person's body has been exposed to or infected by the Corona virus. However, you need to know, the formation of these antibodies takes time, it can even take several weeks.

This is what causes the accuracy of this antibody rapid test to be very low. Even in an observation, it was concluded that the accuracy of the rapid test in detecting antibodies against SARS-CoV-2 was only 18%.

Meaning, if 100 people get negative results from the rapid test, only 18 people are really not infected with this virus. Meanwhile, another 92 people have actually been infected, but are not detected by this test.

WHO expressly does not recommend the use of rapid antibody tests to confirm the diagnosis of COVID-19. Even so, WHO still allows the use of this test for research or epidemiological examination.

2. Swab antigen (rapid test antigen)

In addition to the rapid test for antibodies, there is also a type of rapid antigen test to detect the proteins that make up the body of the virus that causes COVID-19.

This rapid test method is indeed more accurate than the antibody rapid test. However, this test is only accurate on patients with a high amount of virus in their bodies.

While the status is unknown, the accuracy of this test is quite low. Therefore, the use of this test to establish a diagnosis is strongly discouraged.

The only test that can confirm whether a person is positive for the Corona virus so far is the polymerase chain reaction (PCR) examination. This examination can directly detect the presence of the Corona virus, not through the presence or absence of antibodies to this virus.

Procedures and Interpretation of Rapid Test Results

The antibody rapid test procedure begins with taking a blood sample from the fingertip which is then dropped onto the rapid test kit.Next, the liquid to mark the antibodies will be dripped in the same place. The result will be a line that appears approximately 20 minutes later.

The positive (reactive) rapid test results indicate that the person being examined has been infected with the Corona virus. Even so, people who have been infected with the Corona virus and have this virus in their bodies may get a negative (non-reactive) rapid test result, because their bodies have not yet formed antibodies against the Corona virus.

If your rapid test result is positive, don't panic. The antibodies detected in the rapid test may be antibodies against other viruses or other types of coronavirus, not those that cause COVID-19.

As for the rapid antigen test, the examination is quite different. The sample used for this test is the result of a nose and throat swab or it could be saliva. This test can detect the presence or absence of the viral antigen that causes COVID-19 within 15 minutes.

If the rapid antigen test results are negative, you still have to undergo self-isolation, especially if you experience respiratory symptoms. Meanwhile, if the result is positive, there is still a possibility that the antigen does not come from the virus that causes COVID-19.

Therefore, both using rapid antibody and antigen tests, it is necessary to take a swab for a PCR test to determine whether there is true SARS-CoV-2 infection. If the result is positive, self-isolate for at least 10 days from the onset of symptoms and an additional 3 days if the symptoms have not disappeared.

During isolation, avoid traveling and contact with other people who live in the same house, while implementing a clean and he althy lifestyle. Apply physical distancing and always wear a mask.

In addition, whatever the results of the rapid test, continue to monitor your he alth condition. If symptoms of COVID-19 appear, such as cough, fever, hoarseness, and shortness of breath, immediately contact a he alth care facility or COVID-19 hotline for further examination.
