Can RAT detect Omicron subvariants?

Yes, but there is also a possibility that it may not detect the subvariant, unlike the RT-PCR test.

RATs work by detecting specific viral proteins – which help detect COVID infection. But as virus evolves, the viral proteins also tend to alter – and experts say, that this can affect the ability of the test to detect COVID-19. This means that the RATs cannot pick smaller amounts of virus in the body, says Bruce Tromberg, PhD, director of the National Institute of Biomedical Imaging and Bioengineering:

What do we know about RATs in India?

There is no specific information on whether RATs available in India can detect Omicron sub variants. The kit is manufactured by Tata Medical and Diagnostics named OmiSure and MyLab's CoviSelf have claimed that they can detect variants of Omicron.

What should I do if I test negative on RAT, but still have COVID symptoms?

In such cases, multiple experts have told FIT , that a RT-PCR is advised if someone is showing symptoms of COVID, but is repeatedly testing negative on an at-home test.

What should not be done while using home-test ideas?

Storing at the wrong temperature Using straight from the fridge Taking the test too soon or too late after exposure Contaminating the test by touching the swab Eating, drinking, chewing gum, brushing your teeth or smoking before a saliva test Reading the result too early or too late

Do you have COVID-19 symptoms but are repeatedly testing negative on the home test? Can you really trust a COVID home test to diagnose Omicron subvariants?

As reports of COVID-19 surge is causing a flutter across the globe, including India, how we test, track, and genome sequence play a key role, say experts.

So, how likely is it that your at-home Rapid Antigen Test (RAT) shows a positive result? What mistakes should you avoid while using one? Here's all you need to know.
