Omicron: Biologist Explains Why You Might Do Your Lateral Flow Test Wrong

This could turn out to be a crucial part of the test.

A biologist explained how some people can miss a crucial step in their lateral flow or antigen test, and how important this is in detecting Omicron.

While many home test kits advise users to only take a nasal swab, University College London cell biologist Jennifer Rohn urged people with symptoms associated with the Omicron variant to also swab the back in their throats.

In a tweet showing his positive test, Prof Rohn wrote: “Well, there it is. Today with the” bad “symptoms” (ie the common cold) and after a series of LFTs negative, I finally took Twitter’s advice and dabbed my throat as well. like my nose (no easy feat with this diddly stick).

“If you think you might have covid, consider adding the throat sample.”

This involves swabbing your tonsils with the same cotton swab you used to take a sample from your nose.

Harvard epidemiology professor Dr Michael Mina echoed the importance of taking a throat swab and how crucial they can be in detecting Omicron.

He tweeted: “Symptoms are starting [very] early [with] Omicron (for a number of reasons I mentioned). This means that there is a chance that the virus will not yet develop in the nose on the first test.

“The virus can start lower. A throat + nasal swab can improve the chances of a swab catching the virus.”
