 Hi guys, thank you for coming back to my channel. If you are new here, consider subscribing. You will always be the first to know when I upload a new video. Thank you so much for coming back to my channel. I had one question that was coming from Maureen. Maureen is coming from Moradovia. Thank you so much for following me. Thank you so much for the comments and liking the presentations. The question was, why is it that all the airports talk about the PCR test results? Is it the only results that are acquired at the airport? The answer? Yes, depending. But before we go on to the details, with the research of the medical device network, let's first get through what is the PCR testing and what is the tests for COVID-19. The tests for COVID-19 can be divided into what you call the antigen and antibody tests, both of which use different kinds of samples to search for different hallmarks of SARS. COVID-19 to the virus. Medical device network takes a closer look at the different types of COVID-19 tests. One is the polymers chain reaction, which is well known as the PCR tests. These are sent away to a lab to diagnose the disease. We have another one is called the lateral flow tests, which are known as the LVTS. They can diagnose COVID-19 on the spot, but however, some people say or some medical research say they are not as accurate as the PCR tests. Another one is called the antibody or the seroji tests. This can not diagnose an active infection, but they can help to tell if a person has immunity to COVID-19. That is what we have to say. But the question is, what is the PCR testing? PCR tests are used to directly screen the presence of the virus, the viral, which will be detected in the body before the antibody is formed or symptoms of the disease are presented. What does this mean? The test can tell whether or not someone has the virus very early on in their illness. That's why sometimes when you call an emergency ambulance, they will first ask for a few signs how discomfort you feel with your body, what signs do you see with yourself then they can quickly have the response to you. During a COVID-19 testing, a substance known as a reverse transcriptase, or a DNC DNA polymers are added to what you call in a pholazide sample in the lab. This is a small bit of biology, but we need to understand the whole concept. This is so that the enough copies of RNA are present, to signal what you call a positive result. We can say that what we have to know is that the PCR gives us a good indication of who is infected, that is per the universe of success. Senior Ichala in Microbiology, Dr. Edward White. They can be isolated, get in contact with people, they have been in touch with, so they can be quarantined too, just in case. That is why some countries they have what you call the different apps. They will tell you if you get suspected or if you came to mea to a person who has the COVID-19, you will also be separated on quarantine so that you can be quarantined. So that you can try to see if you can have the signs of contraction at one way or the other. Sometime they will say you have to self isolate yourself away such that you can see that you have the signs or not. However, PCR still has its COVIDs. The types of COVID-19 tests need to be sent away to a lab laboratory for analysis, meaning it can take days for people to find out the results. False negatives can occur up to 30% of the time with the different PCR tests, meaning they are more useful for confirming the presence of an infection than giving a patient the cold clear. When we look at the Wauik Medical School Honare clinical lecturer Dr. James Gill said during the course of the heartbreak the PCR testing has been refined from the initial testing procedures and with the addition of greater auto meditation to reduce heras. As we are looking at the swabs taken from people who have a lot of other organisms floating around, we are essentially dealing with the question on how right the results we are looking at. That is a pa Dr. Wauik from the medical school Honare and a clinical lecturer Dr. James Gill. Something we need to remember or something that we need to know is that different airports all need different types of tests for travel or at the point of entry the certificate you have will have to bear a particular recognition type of the test. But remember to some airports you look at the digital or the SMS certificates and not allowed. Look at not allowed at the point of entry and what does it mean? Then we require you to take another PCR testing on arrival which sometimes may be a little bit very expensive for people without an extra coin or money with them at the time of arrival. However for the simplicity or for the accuracy each of the country in the world needs to see that it protects its citizens. It protects its people away from the spread of the pandemic. We can say at one moment that still the PCR gives us a good indication of who is infected and how to deal with that person. What treatment to give to that person? How can we isolate that person away from the other? And how can the virus be dealt with? But remember the most common types of tests that are being used and being accepted by different countries by different point of entry at the airports is what we call the PCR test. We say the PCR test the polymers chain reaction are sent away to the lab to diagnose the disease. What does it mean there and there? It actually means that the results that will come out will be accurate results that can enable to read out the situation or to read out the health of a given person or a given tested person at the time. So guys I think more on thanks so much for the question and this is pretty very good and this is what you ask for. So guys if you need to know something you can put in my subsection of Komet Bureau. I'll always be happy to get back to you as soon as possible. Thank you so much for working to watching my channel. Thank you for the comments. Those that are not subscribed please consider subscribing to my channel. The only channel with the true information. Thank you so much. Next time don't remember don't forget that we shall also look at the other travel requirements. The testing centers our next video will be looking at the testing centers accepted testing centers around the world. The approved testing centers around the world such that if you are to travel you know where you get to get your PCR test result that is genuine to avoid this appointment at the point of entry. Wherever you will be traveling to.
