The latest coronavirus disease outbreak, which was initially found in China in December 2019, is still affecting people worldwide. COVID-19 — the disease induced by an infection — requires prompt and accurate diagnosis to prevent its spread and improve health outcomes.

What Exactly Is The PCR Test And How Does It Work?
A polymerase chain reaction (PCR) test detects genetic material from a specific organism. When a person is infected with a virus, this genetic information may become visible under certain circumstances. Likewise, the test is precise enough to identify the virus even in the earliest stages of illness. It detects viral RNA (ribonucleic acid) inside the body before signs or antibodies appear.
The current travel criterion for deciding if an individual is infected or not is the PCR test. As a result, airlines and the government adopt this test to exert significant control over the virus’s spread.
PCR tests are nothing new, and have been around for quite a few years, however its recent employment against the spread of Covid-19 has caused this simple genetic test to become a major subject in our lives.
How Accurate Is A PCR Test?
The results of RT-PCR tests are accurate in the vast majority of cases. While this test can be performed very early on, if tests are performed too early in the disease’s progression, the findings may not reveal the infection. At this moment, the viral load may be too modest to detect infection.
According to a recent study, the accuracy of COVID-19 samples varied depending on when and how they were taken. So, if you have concerns about testing, talk to your healthcare professional.
As long as you get a test from a trusted testing provider, your chances of getting an accurate test result are very high.
Why Is A PCR Test Required For Travelers?
London PCR testing has shot up in popularity, due to the fact that it is the UK’s biggest city and millions of people fly in and out of London every year. London assures the safety of travellers and individuals in affected countries as COVID-19 spreads. The testing program has been revised to comply with the lateral test standards for day two.
The PCR process duplicates a particular bit of DNA in a material a million times, making it more apparent and thorough inspection. The application of PCR in medical diagnostics has yielded significant results, most especially in our response to the coronavirus. That is why it is considered one of the essential requirements for travellers.
How Long Does It Take To Get Test Results?
RT-PCR samples are frequently analysed in batches at locations other than where they were acquired. It means that test results could take a day or more to arrive, however these times are down to just 12-24 hours in most cases. POC testing, which was recently approved, allows samples to be gathered and tested in the same area, resulting in faster turnaround times.
In the United Kingdom, PCR testing is still the most common way to diagnose COVID-19. Compared to other testing methods, it is a more reliable way to assess and diagnose the disease.
Therefore, contact your doctor if you have mild symptoms or suspect an infection. They’ll assess your risks, generate a treatment and care plan for you, and guide you on how and where to be tested.
