PCR Test | Unilabs - Latest news
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.
Having too much mucus in your nose can dilute the sample and increase the risk of a false negative result. It also provides results in about 15 minutes. The accuracy also differs depending on whether you test positive or negative. An at-home test is most accurate when you have an active infection. So, positive results from a home test are highly accurate. If you test negative again, you can end your quarantine.
COVID symptoms can vary widely from one person to the next. Some people may have very mild symptoms or no symptoms at all. The average time frame is around 5 days. If you do have COVID, the virus is most likely to be transmitted 1 to 2 days before your symptoms start, or 2 to 3 days after your symptoms begin. If you have a moderately or severely compromised immune system, the virus may be able to spread for up to 20 days. This is recommended even if you do not have symptoms. You can take a rapid at-home test.
Regardless of your vaccination status, test yourself again 1 or 2 days later.
