RATs have a much lower rate of accuracy than PCRs, but their convenience and the fact you can typically get a result within 15 minutes are benefits. Their approval was granted by the Therapeutic Goods Administration (TGA), which has also ranked each of those tests by accuracy, with "acceptable sensitivity" being at the lower end of the scale, and "very high sensitivity" being the most accurate.Īny RAT approved for use in Australia must have an accuracy rate of at least 80 per cent. There are currently 15 RATs approved for use in Australia. This will then alleviate the pressure on laboratories and people who are actually conducting the tests."

"That means you may get a test result, which comes back negative … but, in fact, you actually have COVID."Ĭatch up on the latest COVID-19 news here "The advantage of this test is that it's really convenient and you get the results really quickly, but its disadvantage is it's got a much higher false negative rate," Dr Moy said. ![]() Many experts agree, and are calling for a national approach to RATs to help reduce demand on the PCR testing system and ensure those who need one get priority.īoth types of tests serve a purpose, according to the Australian Medical Association's vice president, Chris Moy. couldn't imagine having to go line up for five hours try to get a test in the moment if you actually had COVID, because the symptoms were quite severe for me," he said. Mr Colagiuri does not think it is acceptable to expect COVID-19 positive people to line up for five or more hours for a PCR test.
