Immunity testing could soon be used as a vital tool in the fight against Covid-19.  

Orbis Diagnostics is developing technology, which will be capable of taking a tiny blood sample from up to 15-people at a time. 

About 15-minutes later, it will show a person's level of Covid immunity. 

Scientific Founder David Williams told Mike Hosking they are in talks with the Government. 

"They are engaging and we've had good conversations with the Government. In part, people are waiting for us to produce some trial results." 

The company aims to begin trials from late next month.
