The novel coronavirus is the potential cause of the emerging infectious disease known as COVID-19. During the month of December 2019, the first confirmed cases of COVID-19 emerged. Knowledge of coronavirus transmission and host responses during and after infection are still active research areas.
Can RT PCR test tell if you had Covid in the past?
No, this test can only help you to determine your active infection!
A viral test can determine whether or not someone with COVID-19 symptoms is carrying a virus. It can also reflect the presence of the SARS-CoV-2 virus on a sample of respiratory fluid.
Diagnosing COVID-19 Infection Tests
Molecular Test: It is for viral DNA using PCR technology.
The detection of COVID-19 with a PCR test is very sensitive and specific. Some PCR tests may produce a result in as little as 15 minutes. There are presently a variety of options.
Antigen Test: It detects the proteins on or inside the virus.
Although molecular (PCR) testing is more sensitive than antigen tests, SARS-CoV-2 antigen tests are highly specific. If both a molecular and an antigen test come back positive, the patient is infected and infectious.
It is recommended that negative findings from antigen testing be considered as a presumption. Validated with a molecular (PCR) test if further investigation is warranted because of the lower sensitivity of antigen tests.
The COVID-19 Infection Test
Antibodies are a kind of protein produced by the immune system in response to viral infection. An antibody test involves the examination of a blood specimen. It is often obtained by a blood draw for the presence of antibodies specific to SARS-CoV-2.
An antibody test can only detect the previous infection with SARS-CoV-2, as it might take the body anywhere from a few days to 3 weeks (or more) to produce antibodies following infection.
People who have tested positive for antibodies may still be infectious if their infection happened within the past few days.
Antibodies and SARS-CoV-2
In addition, research is being conducted to investigate if antibodies may protect individuals against reinfection. If so, what quantity of antibodies is required for immunity, and how long protection might continue.
Therefore, those who have tested positive for antibodies to SARS-CoV-2 should not relax their preventative measures, such as maintaining a safe distance from others and avoiding sharing personal items.
At this time, the antibody test is assisting professionals in gauging the extent to which a disease has spread throughout our region.
The CDC will conduct a countrywide COVID-19 antibody study that will last for 18 months. This study will help researchers learn more about the immunological response to COVID-19 and whether or not it declines over time.
The antibody test can also be used to find donors for convalescent plasma, a kind of blood that carries antibodies against the virus and is potentially useful in the treatment of persons who are very unwell as a result of the infection.
