It's not really about that in this context, it's about understanding the existing spread across the country.I also think this priority antibody testing is crap btw - fair enough give priority for actual swab testing for the virus to frontline staff but you cant tell me that it will make any difference if a Nurse tests positive for antibodies or not?
I highly doubt if they dont have antibodies they'll be told to stay off the frontline and make the tea in the staff room - its all hands on deck regardless.
Testing should be rolled out to everyone - the fact they want people to start going shopping and using leisure facilities, public transport in the coming 1-2 months yet wont give us the antibody testing is absolutely crazy.
