Covid testing: How to properly swab for Omicron as expert warns it's 'very different'


The warning comes from American public health scientist Dr Eric Feigl-Ding. He said that it is now becoming clear that Omicron is a “different beast” and so the public should be vigilant with their testing. It came after the UK reported 137,583 new COVID cases and 73 coronavirus-related deaths in the latest 24-hour period.

The latest figures mean that more than 1.1 million people had a confirmed positive COVID test result between December 27 and January 2, 2022.

That’s a 43 percent increase compared with the previous seven days.

But Dr Feigl-Ding believes there could be a lot more.

Posting a picture of a positive lateral flow test, he said: [This is] why you should always swab your that.

“Negative via the nose, positive via the throat.

“Omicron is very different from all other variants.

“We need to adapt to changing testing strategies.”

There are a number of different lateral flows available on the NHS currently, which either require a throat and nose swab, or just a nose swab.

But sharing another photo, Dr Feigl-Ding stated: “The throat swab positive while nasal swab negative testing story is becoming quite common.
