Coronavirus Update: At-home tests’ performance declined after omicron emerged
The performance of certain COVID-19 home-testing kits seems to have deteriorated after the omicron variant emerged, according to a new study published Thursday by the British Medical Journal.
Performance improved when tests were conducted using both nasal and throat swabs, compared with just nasal swabs. However, only the MPBio test using nasal and throat swabs met the WHO’s standards. “Given the less than ideal performance of antigen tests, updates to guidance in the public and private sector should take this into account when suggesting action based on test results,” said Timothy Feeney, research editor at the BMJ, and Charles Poole of the University of North Carolina in an editorial accompanying the study.
The WHO has been criticized for moving too slowly in declaring a pandemic and in warning about the human transmissibility of the virus. The Lancet commission reserved much of its ire for governments for allowing disinformation to spread across social media, which discouraged many people from getting vaccinated once vaccines were available.
