Asked by whether the anti-body testing which are being offered by private hospitals could be a substitute for the swab tests.

Prof. Gauci explained that the anti-body testing is part of a blood test which would determine whether a person has contracted the coronavirus and has developed the necessary antibodies. There are two types of antibodies – IgA which would show that the infection is still at the beginning and IgG which indicates that the person had been infected.
