First of all, it can be used to identify the amplified cDNA from the virus while the PCR is in process. There is a myriad of advantages to using real-time RT-PCR for the diagnosis of Covid-19. Both PCR and RT-PCR can be performed in real-time as well. Highly used diagnostic test, used for viruses such as Ebola. However, the covid-19 virus does not have DNA, therefore it needs to be transcripted from the RNA present in the virus to have PCR be performed on it. When performing PCR, DNA is needed as genetic material to determine the pathogen that is involved in the process. Reverse transcription is a process used to make complementary DNA (cDNA) from a strand of RNA. They perform rapid testing in New Jersey, eliminating the otherwise long waiting period.īefore we determine the differences in both types of testing, we need to understand what reverse transcription is. Very few places can offer this service with results within a single hour and one of these places includes Urgent Medical Care and MRI in New Jersey. Many places offer Real-Time RT-PCR services however most places can take 3 hours or so to determine the results. And this is how the results of the test can be delivered so quickly.Ĭonventional RT-PCR can identify the virus once the process has ended which, for covid 19, might be just too much time considering the risks involved. In a real-time process, the scientists can identify this material while the process is ongoing instead of waiting for it to end. The test used fluorescent dyes as markers to identify genetic materials that are specific to the virus being tested for. RNA is nucleic material similar to DNA but with only one strand instead of two like DNA does. RNA (ribonucleic acid) is a single-stranded nucleic acid and it is usually found in viruses as viral RNA. The reaction uses RNA as testing material. RT-PCR stands for Reverse Transcription Polymerase Chain Reaction. Naturally, in times of peak Covid crisis, we need quick and efficient testing to be able to take subsequent actions as quickly as possible as well. The interesting bit about this test is that it can give you the results within an hour of being performed. Real-Time RT PCR is a highly sensitive method of testing for different viruses, including the Covid-19 virus. Read our full coverage on COVID-19 here Loading.The world is ridden with the Coronavirus Pandemic and even though travel restrictions are not as strict as they were during the initial stages of the pandemic, RT-PCR testing is still crucial for anyone planning to travel at this time. Home quarantine will be scrapped but a testing regime will remain, we're expecting more detail on this in the coming weeks. That's an area with 4G mobile coverage and a vaccination rate of 80 per cent (of 16+) or above. Currently that's Greater Darwin and Alice Springs.įive days before Christmas things change slightly.įrom December 20 anyone entering the Territory will need a rapid antigen test upon arrival, or at the closest regional centre if arriving by road. It's worth noting that once you leave home quarantine, you'll need to spend a further seven days in a high-vaccination zone. You'll then need a PCR test on day five, when you leave quarantine, on day eight and again on day 14. Only fully vaccinated people are allowed to enter the NT, unless you're a returning Territorian or essential personnel.Īs it stands, anyone entering the NT from a red zone is required to receive a negative PCR test within 72 hours prior to arrival, you'll also need a rapid antigen test upon arrival at the airport or at the closest regional centre if travelling by road, before entering seven days of home quarantine. "Whereas, with the proteins, there isn't an amplification process so it's easier to pick it up if someone's got a high viral load but not so easy to pick it up if they don't." "The PCR is much more accurate because what happens is the sample goes into the machine and the machine is able to amplify and replicate up that genetic material to a point where it's easily detectable," she said. While that's convenient, Professor van de Mortel said the PCR tests provide a more accurate result. The PCR test identifies viral nucleic acids or genetic material.Ĭatch up on the latest COVID-19 news here What is a rapid antigen test?Ī rapid antigen test, which identifies viral proteins, can return a result within minutes and can be done at home. "The polymerase part is because that's the name of the enzyme that's used in the test, the chain reaction part is because there's a series of cycles in the machine that give you the test result at the end," Professor van de Mortel said. Griffith University infection prevention and control expert Thea van de Mortel said PCR stands for polymerase chain reaction. ![]()
