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.

It's up to you to go green
Nils El Accad, chief executive and owner of Organic Foods and Café, says going green is about “lifestyle and attitude” rather than a “money change”; people need to plan ahead to fill water bottles in advance and take their own bags to the supermarket, he says.
“People always want someone else to do the work; it doesn’t work like that,” he adds. “The first step: you have to consciously make that decision and change.”
When he gets a takeaway, says Mr El Accad, he takes his own glass jars instead of accepting disposable aluminium containers, paper napkins and plastic tubs, cutlery and bags from restaurants.
He also plants his own crops and herbs at home and at the Sheikh Zayed store, from basil and rosemary to beans, squashes and papayas. “If you’re going to water anything, better it be tomatoes and cucumbers, something edible, than grass,” he says.
“All this throwaway plastic - cups, bottles, forks - has to go first,” says Mr El Accad, who has banned all disposable straws, whether plastic or even paper, from the café chain.
One of the latest changes he has implemented at his stores is to offer refills of liquid laundry detergent, to save plastic. The two brands Organic Foods stocks, Organic Larder and Sonnett, are both “triple-certified - you could eat the product”.
The Organic Larder detergent will soon be delivered in 200-litre metal oil drums before being decanted into 20-litre containers in-store.
Customers can refill their bottles at least 30 times before they start to degrade, he says. Organic Larder costs Dh35.75 for one litre and Dh62 for 2.75 litres and refills will cost 15 to 20 per cent less, Mr El Accad says.
But while there are savings to be had, going green tends to come with upfront costs and extra work and planning. Are we ready to refill bottles rather than throw them away? “You have to change,” says Mr El Accad. “I can only make it available.”

“Attacking places of worship is a form of terrorism and extremism that threatens peace and stability within societies,” it said.
The council also warned against the rise of hate speech, racism, extremism and Islamophobia. It urged the international community to join efforts to promote tolerance and peaceful coexistence.

Who was Alfred Nobel?
The Nobel Prize was created by wealthy Swedish chemist and entrepreneur Alfred Nobel.
- In his will he dictated that the bulk of his estate should be used to fund "prizes to those who, during the preceding year, have conferred the greatest benefit to humankind".
- Nobel is best known as the inventor of dynamite, but also wrote poetry and drama and could speak Russian, French, English and German by the age of 17. The five original prize categories reflect the interests closest to his heart.
- Nobel died in 1896 but it took until 1901, following a legal battle over his will, before the first prizes were awarded.
