Do you know where the Covid19 Swab Test is carried on? The novel coronavirus tests are administered in county health labs, private or commercial labs. The test has many things involved which we should have knowledge and awareness about. Let us understand the entire procedure of the test.
Covid19 Swab Test
A Covid19 Swab Test is not always acceptable or friendly for many because it is a bit different and can sometimes be injurious (if not done correctly). It necessitates the insertion of a long swab into the nose and mouth termed as nasopharyngeal swab and oropharyngeal swab, respectively.
In the nasopharyngeal swab test, the swab is rotated multiple times from both the nostrils and ensured that enough sample is collected for analysis. This diagnostic test involves testing of cells and fluids from the respiratory system to identify particular genes for the SARS COV-2 virus leading to COVID-19.
In the oropharyngeal swab test, the sample for the test is collected from mouth to backside of the throat. It is also not that pleasant and can cause irritation to throat inducing cough and sometimes choking.
These tests are performed by a skilled and experienced health care personal only in the supervision of doctors.
Antibody Test For Covid-19
An antibody test, also called a serology test, is done to screen the antibodies present in the human blood. Whenever our body fights against any infection, it naturally creates antibodies. The same is the case when our body fights against COVID 19. In this way, our body tries to build immunity against viruses and bacteria.
Similarly, getting a vaccination against certain diseases means the same i.e., getting antibodies that can fight against the virus.
The antibody test is not for checking the virus but for checking your immune system capable of fighting against the disease.
A minimal amount of blood is collected from the finger for this test, and both types of antibodies for SARS-CoV-2 are tested (IgM antibodies and IgG antibodies). The IgM antibodies are diagnosed in the early stage of infection, whereas IgG antibodies occur in the later stages. Mostly, the IgG antibodies tend to stay in the body for a long time after the infection flees away.
Among all other tests, RT-PCR is the most precise diagnostic Covid19 test currently carried on everywhere. This test is only possible if the patient is actively tested as positive. The PCR test is performed to identify the genetic report (RNA) of the virus.
Rather than detecting the immune response of the body, the test precisely identifies the occupancy of an antigen. If the RNA of the virus is detected in the body of a person (before the creation of antibodies or before the indication of any symptoms of the illness), the test depicts the presence of the virus at the early stage.
PCR is thus, a very good source of viral infection detection.
