Antibody testing

Covid 19 antibody testing is underway at work. Of course it’s just a public health exercise to look at the prevalence of those with antibodies especially in those of us working for the NHS. I’m curious to know though but am suspecting will be negative as not had any symptoms at all. Apparently it will take ages to get a result as our trust is only able to process 300 a day and of course every body is keen to be tested!
