WHAT IS THE ISLAND THAT GETS PCR INFORMATION AND DAY ENERGY?
A PCR test can cost up to £ 180 per person, and the swab must be processed in a laboratory.
On the other hand, the UK favors faster non-laboratory based tests that give results within 15 minutes.
These rapid coronavirus tests, called late-flow tests, are those that can be performed in place using portable equipment.
They are faster and cheaper than laboratory-based PCR tests, which the government uses to test people, but which are less accurate.
UPDATED INFORMATION – SACRIFICE ONLY
In a lateral flow test a swab is used to get a sample from the person’s nose or throat and is then processed in a small device that tries to detect the coronavirus by mixing the sample with something to which the virus would respond.
If there is a reaction in the mixture it suggests that the person is carrying a coronavirus. If not, they will get a negative result. This process can be completed in as little as 15 minutes.
You take your own swab even though an on-site professional processes it through the tool.
Lateral flow misses up to half of the cases, with the Department of Health’s own permission.
But damaging evidence shows that they can be effectively useless when self-administered, despite the fact that the conventional Downing Street test scheme relies on people taking their own swabs .
The tests are more accurate when swabs are performed by trained professionals as they need to be pushed deep inside the nose.
But scientists fear Britain has only the money or enough extra medicine to do this across the country every day, with health leaders instead taking swabs. DIY to save time.
PCR RESULTS CAN BE DETERMINED DAYS – NOW THERE IS MORE RISK
These late flow tests are different from the gold standard PCR test – scientifically known as the polymerase chain reaction test.
PCR tests also use a swab but this is then processed using high-tech laboratory equipment to examine the genetic sequence of the sample to see if any of it matches the coronavirus genes. .
This is a much windier and more expensive process, in which several types of workers are trained, and the analysis process can take hours, with the whole process from swab to someone getting the result. taking days.
It’s a lot more accurate, though. In extreme cases the tests are almost 100 percent accurate at seeing the virus, although this may be more like 70 percent in the real world.
This compares with much lower sensitivity in late-flow tests, with a single-type test used in Liverpool suggesting that they miss around 50 per cent of people who would be positive with PCR.
SO, WHAT IS A DAYTIME LIGHT?
A real fact could be an advantage for PCR now that so many people are infected, however, with the tests being able to detect strains of the virus in people who passed away weeks ago. and no longer contagious, who may have to make themselves uselessly lonely.
Lateral flow tests are more likely to miss people who carry the virus but, experts say, have value as a way to reduce people who carry much of the virus and are therefore more likely to spreading the disease.
