What Is PCR Testing?


With Covid-19, many concepts that we are not accustomed to have entered our lives. While

struggling with the pandemic, we tried to protect our health by trying to learn all of these concepts in detail. Which surgical mask is more protective? Which disinfectant protects us against the virus without harming our skin? We tried to find answers to questions like these. 


Covid-19 tests are another concepts that we want to learn in detail in this process. So, what do we know about the covid-19 tests that we get even when we have the slightest flu?


The PCR test, which is the most widely applied test in the Covid-19 testing process, detects genetic material. In the first few days of the virus entering the body, it can detect the virus in the body even before the infection shows any symptoms. PCR tests are performed in hospitals and clinics. The results of the tests can vary from 24 hours to 2-3 days.


PCR, also known as Polymerase Chain Reaction, is the general name for a molecular replication method. While it is mainly used in gene studies, it has also become useful for laboratory and clinical studies over time. This method, which is based on the analysis of the DNA in the sample taken, is also used in the detection of bacterial infections. PCR tests, which are performed by separating the sample by heat, are a reliable, fast, and easily applicable method in the detection of COVID-19 infection today. The tests are used to determine whether the genetic material of the virus is present in the sample taken from the person. For the test, a long swab is taken from the nose and throat of the people and this sample is sent to the laboratory for analysis. Results are available in 24 hours to 3 days. In the laboratory analysis, the RNA sample of the person being tested is analyzed for SARS-COV-2 RNA.

However, PCR testing is not the only method for detecting the covid-19 virus.

What Are The Different Types Of Covid-19 Test

  • LFT, also known as the Lateral Flow Test, uses similar technology to a pregnancy test. These tests look for antigens on the surface of the virus.They are designed to identify asymptomatic persons and have been used across the UK following a pilot in Liverpool. A swab is placed in the nose or throat, then the sample is briefly placed in a tube of liquid, which extracts the molecule that determines whether COVID-19 is present. No laboratory equipment is needed as a few drops of liquid are then dropped onto a small strip. Test result comes out in as little as 15 minutes, but there are questions about its sensitivity. Therefore, it cannot be said to be as reliable as the PCR test.

  • The antibody test looks at whether your body has produced any antibodies against the virus. A blood test is taken from a person with symptoms of COVID-19 that disappeared three to four weeks ago, and it is tested to see if any antibodies in the blood bind to a unique protein made by the virus. Needling tests are being developed where the person can do their own blood test, but they are not yet available. Unlike other diseases, the UK government and the World Health Organization agree that there is currently no evidence that someone with antibodies will not have the COVID-19 virus in the future. A study by Imperial College found that protective antibody levels drop "pretty quickly" in people with COVID-19.

Of course, the one who has covid-19 symptoms has to have a PCR test for a healthier environment. But now that life is slowly returning to normal, these tests are necessary not only when we show symptoms, but also for the safety of ourselves and our environment in many other areas of life. Almost every country has its own regulations for travelers. Now, we have to have a PCR test for travel and comply with the travel restrictions and regulations of the country we are visiting. 

It can be quite complicated to check the country's regulations and search the labs and clinics for PCR testing in detail every time. But no need to worry because thanks to FurtherPass, you can have your PCR test in the city you want and have a safe trip.
