Dr Ashwin Swaminathan, an infectious diseases physician and senior lecturer at the Australian National University, said the performance of the tests with different variants was “a moving feast”.

“[The TGA] are doing it in real time, releasing results as they go along,” he said. “It’s the role of the TGA to make it clear what a test can and can’t do.

“In the context of governments buying up all these tests and distributing them to schools and workplaces and vulnerable people in society, where it’s a major part of our strategy going forward, we really need to know what the tests can do.”

There have been ongoing supply shortages of the rapid antigen tests amid bickering over whether government demand has diverted supply from pharmacists.

Dean Whiting, the chief executive of Pathology Technology Australia, said high-quality products identify the presence of the “nuclear capsid protein”. This is a “highly conserved” part of the virus which is much less likely to mutate, unlike the spike protein.

It is the spike protein that has mutated to form new variants, and Omicron has many mutations, allowing it to dodge vaccine antibodies and making the booster jabs necessary.

The real money is going to be in the quality contracts with logistics and other companies.
Will Souter indicated clients are willing to pay a premium for the extra quality, monitoring and connect with Atomo.

So, you have tests that claim 90% sensitivity, but that may be to spike proteins and over the long term, not useful. Apples are not oranges.
