An emergency physician has explained three common mistakes people make when using lateral flow tests.
Lateral flow tests (LFTs) have quickly become an important part of our daily lives during the pandemic and are crucial in detecting and preventing the spread of covid infections.
But with some results invalid when using an LFT, people are being urged to make sure they use the tests correctly, the Manchester Evening News reported.

Dr. Nathan is an emergency physician in London who shares advice about Covid on his Instagram, @expedition_doctor.
He has revealed the three biggest mistakes that are made at home that can lead to an inaccurate LFT result.
According to Dr. Nathan is the three mistakes: failing to look positive, not reading the instructions, and mixing the best way to perform the test.
He said: “Any positive streak within 30 minutes, even if it is so faint that it is barely visible, equals a positive result.
“But if there is a faint line after 30 minutes, this can be ignored.
Do not forget to avoid eating or drinking for at least 30 minutes before brushing your nose and washing your hands!
“Always follow the instructions provided.
“If the test advises taking a throat and nose swab, do so. If it only recommends a nose swab, do so.
“That said, there are some anecdotal reports of people getting a positive throat graft and a negative nose graft, and later developing symptoms and a positive PCR.”
As of Tuesday 11 January, the government has said that it will no longer be a requirement to get a PCR test after a positive LFT test in the UK if the person has no symptoms.
Anyone who tests positive with an LFT must still isolate themselves for the required period, although this can be shortened if the person tests negative on an LFT on days six and seven.
The rules around testing for people with symptoms remain the same.
Anyone who experiences one of the three main symptoms of coronavirus – a new persistent cough, fever or loss of taste or smell – should get a PCR test right away.
Dr. Chaand Nagpaul, chairman of the British Medical Association (BMA), told Sky News that it was important that “the government does not just wait to run it out, because every day people are suffering.”
