What Is the RT PCR Test and When Should You Take It?
Reverse transcription polymerase chain reaction test is the full form of RT PCR, which consists of two distinct steps. The first one is when the reverse transcription process is performed, after which the amplification of the DNA sequence is executed using PCR. It can be used to detect RNA in a sample with higher precision. It is used to detect the presence of specified genetic materials like RNA from viruses like SARS – Cov – 2 or influenza.Â
As we know viruses are difficult to spot because of their small size but there are some modern nuclear derived techniques, like real-time RT PCR test that allow us to identify them. It has made the detection of covid virus easy as it can detect this in real time with advanced mechanism.Â
What is the RT-PCR test?
The COVID-19 real-time reverse transcription-polymerase chain reaction (RT-PCR) usually tests the upper and lower respiratory specimens, such as swabs, sputum, nasopharyngeal, and other specimens of patients who are suspected of COVID-19. Nasal related health discomfort or throat swabs of an any of the individual are collected under the observation of a healthcare practitioner, or a self-collection kit can also be used that is commercially approved for use in this test. This test focuses on the extraction of ribonucleic acid (RNA), a genetic material of the COVID-19 virus. The test analyzes the genetic sequences such as the SARS-COV-2 virus, and then the results are positive. The test result would be negative if there is no presence of the virus in the sample collected from the patients.
When should you take an RT-PCR test?
You should take a RT PCT test when you have certain symptoms of COVID-19. If you are feeling discomfort and experiencing some signs of fever, cough, fatigue, or if you have lost your smell or taste and are facing some difficulty in breathing, then you should get tested for COVID-19 through the RT-PCR test. Early treatment may help you in preventing the spread of the virus and properly managing the disease. If you are having some symptoms of COVID-19, then you must do the test using the RT-PCR method.Â
Conclusion
RT-PCR tests are considered the best and most effective method for identifying many infectious diseases, including COVID-19 and HPV. As they detect the infections before they start affecting the body. These tests play a very important role in preventing the spread of diseases.
As we know that there is very little risk in having this test. A healthcare professional will take a sample of your blood, saliva, mucus, or tissue. This sample contains DNA and possibly the DNA of a pathogen or cancer cell. To detect COVID-19, you have to change RNA into DNA, as it is made up of RNA, so RNA must be changed into DNA before copying. This process is called reverse transcription PCR(RT-PCR). PCR tests can find the signs of disease in the early stages of infections. Other tests could sometimes miss early signs of these types disease, but the RT-PCR test could always detects the early stage of the infection.
