Why does pcr test take so long – none:. Which COVID-19 Test Should You Get?
In the face of the surge in Omicron cases the Government changed the rules so some people won’t have to wait for a follow up PCR test, after getting a positive lateral flow. Those testing positive on a lateral flow are now required to isolate for five full days, and can leave quarantine on day six after negative tests on day five and six.
If you’ve got symptoms of the virus, you can get a test and there are 12 other reasons that you can still access a follow up PCR. The NHS says you can get a free PCR test if you have a new persistent cough , a high temperature or a loss of taste or smell. You can also do a lateral flow test at home which takes just 30 minutes and due to Omicron cases being high across the UK, people are urged to just take these.
While Omicron cases remain high, they are falling and most people who catch the bug say they have cold-like symptoms. A string of hugely positive studies show Omicron IS milder than other Covid strains, with the first official UK report revealing the risk of hospitalisation is 50 to 70 per cent lower than with Delta.
Covid booster jabs protect against Omicron and offer the best chance to get through the pandemic , health officials have repeatedly said. The Sun’s Jabs Army campaign is helping get the vital extra vaccines in Brits’ arms to ward off the need for any new restrictions.
PCR polymerase chain reaction tests are the gold standard and are sent off to a lab to be properly processed – unlike lateral flow tests that can be completed at home in less than an hour. It is sent to a laboratory where a lab technician looks for genetic material of the virus using highly specialised equipment. The PCR tests are much better at finding very small amounts of the virus, especially early during an infection.
So these are used primarily in people who have Covid symptoms. It uses a long cotton bud, which takes a swab of the inside of your nose and the back of your throat. NHS Test and Trace figures show around 95 per cent of people get a result in 24 hours if they are tested under Pillar 1, which covers places like hospitals and outbreak spots. But around 60 per cent of those tested at large drive-through centres, under Pillar 2, get their result back in 24 hours.
For example, results may take longer to come back during very busy periods or peaks of waves because labs are swamped with tests. Usually the result is sent to you via text or email when it’s ready. If you have the NHS Covid app, the result might come to you that way. If you do not get your results by day six, then call Calls to are free from a landline or mobile phone.
Lines are open from 7am to 11pm. If you test positive for Covid , you have to self-isolate. It’s a legal requirement to self-isolate if you test positive or are told to self-isolate by NHS Test and Trace. You could be fined if you don’t. Yesterday the government announced that isolation rules would be slashed to five days, after previously cutting it from 10 days to seven.
The new rules mean if you test negative using lateral flow tests on day six and seven of isolation, with tests taken 24 hours apart, no longer have to self-isolate. If you tested positive with no symptoms on a lateral flow, you don’t need to take a PCR anymore, and this counts as day one of your isolation. If you had symptoms and then tested positive on a lateral flow, your isolation began when you first noted symptoms.
But those who leave self-isolation on or after day seven are strongly advised to limit close contact with other people in crowded or poorly ventilated spaces, work from home and minimise contact with anyone who is at higher risk of severe illness. Although new rules coming in on January 17, will mean people in England can leave isolation after five full days , if they test negative on day five and six. If you test positive, your self-isolation period includes the day your symptoms started and the next seven full days – unless you keep testing positive.

PHO performs thousands of COVID diagnostic tests every day in partnership with many hospital, academic and private labs across the province. This network of labs, coordinated by Ontario Healthcame text in earlyin order to meet the increased demand for testing. This means that we provide support to new labs as they come online with testing ttest also ttake early samples from those labs to confirm the accuracy of the testing. The OCGN is comprised of representatives from clinical and public health laboratories undertaking genomics testing, government, public health and research centres.
Find out more about the difference between these two types of tests and their application. As new and emerging variants become known, laboratory systems around the world, including our lab at PHO, are required to adapt and shift to proactively monitor for these variants and understand how they are spreading in Ontario.
If you are required to isolate, you cannot leave your home for any reason unless you are going to get tested for COVID or have an emergency. For more information, see our How to Self-Isolate Fact Sheet and follow current public taje advice on how long to remain isolated.
