What is RT-PCR Test | What is CT Value in RT-PCR

What is RT-PCR Test | What is CT Value in RT-PCR: Corona transition is at its peak in the country. In many states, the situation has become fragile. In these circumstances, there is a discussion about testing through the RT-PCR test. RT-PCR test has been made mandatory in most of the states of the country. In addition, several states in the country, including Gujarat, have recently announced a reduction in test charges.

Here we are going to give information about what is RT-PCR test, what is the significance of CT value in the report as well as how much is charged in different states.

What is RT-PCR Test?

- RT-PCR (Reverse Transcription Polymers Chain Reaction) Test. In addition, rapid antigen and antibody tests are also done. If the rapid antigen test is positive, then the person is positive for corona. But if the test is negative and symptoms of corona still appear, it becomes necessary to have an RT-PCR test.

- Through this test, the person gets information about the virus. In which the ribonucleic acid (RNA) of the virus is examined. Making RNA from deoxyribonucleic acid (DNA) is called transcription.

- Of course when the process of making DNA from RNA is called reverse transcription. The Covid-19 virus does not contain DNA. This means that any probe is possible through DNA, but RNA occurs in these circumstances when it is not possible to detect the Covid-19 virus based on DNA. That is, the RNA of the coronavirus is converted into DNA.

- i.e. reverse transcription-polymers chain reaction is investigated. For this, a sample is taken from any part of the person's body. Swabs are usually taken from the inside of the mucosa from the nose and throat and examined in the laboratory. An RT-PCR test report usually takes about 8 hours to arrive.


What is CT Value in RT-PCR

- According to the Indian Council of Medical Research (ICMR), the RT-PCR test measures SARS-CoV-2 and then measures its positivity based on the cycle threshold (CT).

- Samples need cycling several times to detect how much transition there is in a person. In these circumstances, if the CT value is 35 or less then the person appears to be infected. And if this value is less than 22 then hospitalization is required. CT values ​​23 to 39 are considered appropriate. Even in these circumstances, a CT scan is advised to find out how widespread the infection is.
