PCR tests have been made compulsory for all travellers arriving in the UK as a way to fight the newly discovered coronavirus Omicron mutation.
Accepting only PCR tests means the price goes up for the travelling public as the previous option — a lateral flow test — was cheaper. There are also differences in the time it takes to obtain results and accuracy rates.
UK Prime Minister Boris Johnson announced the move to only PCR on Saturday, a day after the World Health Organisation called Omicron a “variant of concern.”
“We're not going to stop people travelling, but we will require anyone who enters the UK to take a PCR test by the end of the second day after their arrival and to self-isolate until they have a negative result,” Mr Johnson said.
The devolved administrations in Scotland, Wales and Northern Ireland have adopted similar measures for travellers.
So what is the difference between the two tests?
Price tag
Polymerase chain reaction, or PCR, tests cost about £65 ($86) and in-store ones retail for about £85. Private clinics tend to charge about £200 per test.
These prices are significantly higher than for lateral flow tests which can be sold for anywhere between £5 and £30.
When PCR tests were scrapped in favour of lateral flow tests, the move saved families hundreds of pounds per trip.
Taking the test
Both require a swab to be taken from the nose or throat.
For a PCR, the swab has to be sent to a laboratory where researchers analyse it and the result is delivered to the customer, usually be email.
This can take up to two or three days, depending on whether there are any backlogs in labs.
The LFT swab on the other hand is inserted into a capsule of liquid before being poured into a device. The rapid tests have been used in schools and workplaces and for allowing entry to events.
Advice varies but most manufacturers say to wait about 15 minutes before accepting the results displayed.

Test results
PCR test results are sequenced in labs to pick up variants of concern and that includes the Omicron mutation. This is why they are recommended for people experiencing Covid symptoms.
Because of their high reliability in this regard, the UK government was, for a long time, reluctant to replace them with LFTs.
The government also realised the quality of lateral flow tests has improved since the start of the pandemic.
Travel companies have long said that pricey PCR tests are deterring people from booking flights abroad.

10 tips for entry-level job seekers
- Have an up-to-date, professional LinkedIn profile. If you don’t have a LinkedIn account, set one up today. Avoid poor-quality profile pictures with distracting backgrounds. Include a professional summary and begin to grow your network.
- Keep track of the job trends in your sector through the news. Apply for job alerts at your dream organisations and the types of jobs you want – LinkedIn uses AI to share similar relevant jobs based on your selections.
- Double check that you’ve highlighted relevant skills on your resume and LinkedIn profile.
- For most entry-level jobs, your resume will first be filtered by an applicant tracking system for keywords. Look closely at the description of the job you are applying for and mirror the language as much as possible (while being honest and accurate about your skills and experience).
- Keep your CV professional and in a simple format – make sure you tailor your cover letter and application to the company and role.
- Go online and look for details on job specifications for your target position. Make a list of skills required and set yourself some learning goals to tick off all the necessary skills one by one.
- Don’t be afraid to reach outside your immediate friends and family to other acquaintances and let them know you are looking for new opportunities.
- Make sure you’ve set your LinkedIn profile to signal that you are “open to opportunities”. Also be sure to use LinkedIn to search for people who are still actively hiring by searching for those that have the headline “I’m hiring” or “We’re hiring” in their profile.
- Prepare for online interviews using mock interview tools. Even before landing interviews, it can be useful to start practising.
- Be professional and patient. Always be professional with whoever you are interacting with throughout your search process, this will be remembered. You need to be patient, dedicated and not give up on your search. Candidates need to make sure they are following up appropriately for roles they have applied.
