Polymerase chain reaction (PCR) testing was thrown suddenly into the spotlight during the COVID-19 pandemic, and is now something almost everyone is far too familiar with
The method is used to rapidly make millions to billions of copies of a specific DNA sample, amplifying a very small sample of DNA to make a large enough amount to study in detail. Using PCR testing, scientists are able to identify COVID-19 in saliva samples.
PCR tests can generate results in just a few hours. This speedy turnover is vital to containing the virus and ensuring overseas travel is possible during a pandemic. Additionally, PCR tests are generally considered more reliable than lateral flow tests due to their extremely high specificity.
Fit to fly PCR testing has been a requirement of many countries in order to prevent the COVID-19 virus – and its many mutations – arriving from abroad. As a result, when the borders reopened, a number of facilities focused on meeting the demand. So when, in September, the UK government announced it was stopping fit to fly PCR tests for vaccinated arrivals, it was a shock – and a blow to these organisations.
But, in light of their ever-shifting travel policies, does the UK government’s U-turn really mean the end of fit to fly PCR tests?
What are the PCR test requirements for travelling now?
Starting 4 October 2021, pre- and post-arrival PCR tests are no longer a requirement for double-vaccinated individuals travelling into the UK. These people will only be required to show a lateral flow test. Those who are unvaccinated, however, will still be required to do a PCR test before and after arriving in the UK.
Outside of the UK, the requirements for PCR tests vary from country to country.
