The DOCTOR has revealed the correct way to perform the lateral flow test, and you may have been doing it wrong all this time.
Dr Eric Levi, an ENT surgeon from Melbourne, Australia, points out the proper technique to avoid “poking the brain”.
He also cautions that some methods fail to obtain adequate samples.
This can give false negatives if not enough virus particles are collected.
Side stream testing is a key tool to prevent the spread of viruses. They tell if someone is carrying Covid in less than 30 minutes.
But doing it wrong, the risk of them being incorrect increases.
Same goes home PCR test kits, which also requires a letter.
Picking yourself can be uncomfortable, causing watery eyes, watery eyes, and sneezing, and in very rare cases, nosebleeds.
A Finnish study published in JAMA . magazine revealed that of the 600,000 swabs, four suffered severe nosebleeds while four others had to surgically remove the broken swab from their nose.
A woman in IowaAmerica, with a brain leak, causes a metallic taste in the mouth, runny nose and headache after pushing the swab too far, doctors said.
How to use Covid test strips properly
But many people point the long gauze upward, directing it to the center of the eye.
“If you sweep in this direction, you’ll hit a narrow roof,” he said. It’s painful. Don’t do that. ”
In a separate video, he says that the upward poke “touches the brain” – which is certainly not ideal.
Showing perfect technique, Dr. Eric tilted the gauze horizontally, towards the center of the back of the head.
“What we wanted to get was the mucosa, the airways of the nose, it’s forward and backward,” said Dr.
“So go flat, aim backwards and go slow, go low.”
The ear, nose and throat surgeon says the cotton swab should be turned back about 2-3cm and rotated for 12 to 15 seconds.
Another person also demonstrated twirling a cotton swab around the nostril.
“It’s not a great model,” he said. “It’s just brushing the hairy part of the nose in the front.”
Insufficient sampling may mean that the lateral flow test does not pick up viral fragments. This can produce “gaps” or “false negatives”.
How to pick a child
Dr. Eric also shows how to safely perform an lateral flow test on a child with the help of his daughter, who he named Moana for the video.
He said on TikTok: “She was sitting comfortably on the sofa, my hands behind her back to support her head.
“I will pick her nose, just remember that going up is painful, always going down, going low and slow.
“I put my little finger on her chin to steady my hand.”
Dr. Eric slowly inserted the cotton swab into Moana’s nose at a horizontal angle, about 2-3cm, gently rotating it a few times before removing it.
Covid side flow test kits always come with instructions on how to perform them.
The NHS kit says children under 12 should be screened by an adult, while those aged 13 to 17 can do it themselves with adult supervision.
When examining children under 12 years of age, the kit states that the swab should be rotated five times in the nostril and that “no force is required”.
In the UK, children under the age of 11 do not need to take rapid tests to go to school.
However, the guidelines say that people under the age of 5 to 18 should perform a lateral flow test every day if they have been in contact with someone with Covid.
The Government website reads: “If you are 5 years of age or older and have been identified as someone’s contact with Covid-19, but are not required to legally self-isolate, you are advised to:
- take an LFD test every day for 7 days or up to 10 days from your last contact with someone who tested positive for COVID-19 if this happened earlier
- Take this daily quiz before you leave the household for the first time that day. ”
