How PCR Test Detect COVID-19

The world is suffering from the COVID-19 epidemic. In order to regulate the epidemic, nucleic acid testing is needed. PCR test detect COVID-19 is an effective method. This can make it easier to recognize the epidemic situation, prevent more people from inadvertently infecting them, and also facilitate the infected to receive timely and operative treatment, and further sustain social stability. Since the early days of the epidemic, PCR tests have been generally used to diagnose COVID-19 nucleic acid.

So what is the PCR test? And how does this test experiment work? That’s what we’re going to say next.

PCR is an abbreviation, it means polymerase chain reaction. It is a molecular biology technique for amplifying specific DNA or RNA fragments, which can increase the replication of small amounts of selected DNA or RNA. The PCR test can detect the genetic material of the virus. PCR is a powerful and widely used experimental tool, the biggest and most common use is the diagnosis of disease. PCR can be used to detect a variety of conditions and diseases, such as COVID-19 tests, HIV detection, breast cancer detection, cervical cancer screening, etc.

The testing laboratory uses PCR to amplify a small amount of RNA in the sample into DNA, which is then replicated continuously, and then the virus detection of the sample is carried out. PCR tests can detect evidence of disease at the earliest stages of infection and are highly accurate. This method can analyze your upper respiratory tract sample for the genetic material of SARS-CoV-2, which is the virus that causes COVID-19.

The Process of PCR test detects COVID-19:

Before the test is officially carried out, the first is sample collection: the physician will use a swab similar to a cotton swab to collect the respiratory material in the throat or nose of the test person. After collection, the swab is sealed in a test tube and delivered to the laboratory for the next step.

When the testers in the laboratory receive the sample, they will extract the genetic material from the material in the sample and perform PCR. Some chemicals are used in this stage, and when the PCR amplification cycle reaches a certain level, the sample with the viral genetic material will be Causes the chemicals in the tube to fluoresce, which the PCR machine detects as a positive result.

If your test result mentions a CT value, the CT value defines how many cycles the PCR method takes to reveal a positive result. The higher the CT value, the lower the possibility of infection, which means that you can quickly recover by seeking medical treatment at the early stage of the infection. The lower the CT value, the higher the number of viruses in the body, the higher the possibility of infection, and the more serious the degree of infection by the virus.

The COVID-19 test results are normally returned to you within 24 hours, but different medical institutions in different regions may have different times. If your test result is negative, it means that you are not infected and healthy, and then please continue to take precautions to guarantee that you are not infected by the virus. If you test positive for the virus, please contact your local authorities as soon as possible, stay at home, close your doors, and stay away from others.

This is all about PCR tests to detect COVID-19. We hope everyone who can view this news is healthy during this special time. PCR plates and PCR tubes are usually used in laboratory PCR experiments. If you need to buy this equipment, Hawach hopes to be your choice.
