Where is the best place to test RT-PCR?
To say that are we infected with COVID? most precise The fastest and most effective at present is RT-PCR, which stands for Real-Time polymerase chain reaction, which is a thorough detection of immunity due to infection.
PCR is a test for COVID-19 infection that is used to test for people infected with SARS-CoV-2, also known as Coronavirus, which causes COVID. the most Because the results are accurate and fast, including the most reliable.
Testing is often recommended to have a Rapid Antigen Test first, but in other countries. There will be a RT-PCR test at all. If there are symptoms that are expected to be infected at any time, you can go check immediately. And it is advisable to check if found close to the risk group.
The Rapid Test can be performed at home, but the results are not as accurate as the RT-PCR test, where the Rapid-Test readings only tell whether it detects or not from 2 lines without being tested in a lab. Therefore, RT-PCR examination is more accurate.
What does RT-PCR stand for?
The term RT stands for Real-Time, and the term PCR stands for polymerase chain reaction. nuclear-derived using detector Strange creatures in the human body Especially checking whether there is a virus or not.
Real-Time – Immediate results in the lab
That said it came from a word used about nuclear because before It applies to the use of radioisotopes to detect living organisms. But when it comes to medicine It has been changed to detect. virus indicator and strange creatures which scientists in the lab It can be seen immediately (Real-Time) while the virus is dividing, which RT-PCR is a test in that regard.
It is one way to increase the amount of genetic material. By stimulating the main components, DNA Template (original) and Primers (nucleotides) After collecting samples, DNA templates are obtained along with Primers mixed with Nucleotides, Taq DNA polymerase and Mixed buffer for testing in a PCR Thermal Cycler.
The RT-PCR method is widely used in laboratories for the detection of Covid-19. It has been used in the past for other pathogens such as Ebola, Zika virus, and others (NCBI reference).
How does RT-PCR detect Covid-19?
Collect samples from the swab.
When collecting a sample from a swab, this is done in the same way as the Antigen Test Kit. The genetic material is swept through the nose and throat, with a drop of substance applied to the sample to remove proteins and lipids, after which RNA is extracted. that is in the sample, which this RNA will be the gene of that person, and if infected with COVID, there will be RNA of the virus.
Why should I use RT-PCR to test for COVID?
Antigen Lateral Test Kit results may not be accurate. due to the use of a small assay and did not enter the lab to conduct rigorous testing The use of RT-PCR method is more sensitive. In fact, we know that waiting for results 24-72 hours is waiting for a queue, but the fastest PCR results are 3 hours compared to other methods that take up to 3 hours. 8 hours
But the blind point of RT-PCR is that it cannot be tested. past infection, for example, once infected and then cured, coming to PCR again, will not find That’s because of the virus. will stay in the body for a period of time only.
All this when reading this article. You may start to understand what RT-PCR stands for. There are still many types of examinations such as COVID immunity detection after vaccination which is not recommended but can do If you want to know that vaccine How much quality is there?
