Need to be very careful here - screening test is *technically Ag/Ab (looking for HIV antibodies and p24 antigen). Confirmatory is differentiation assay, which determines which strain of HIV you have. Whatever change we make here might affect the other cards we have been toying with.
All cards have been changed i believe to the correct format, this is the only one that is not in line as far as i can tell.
I swear of I see this card one more time I’m gonna KMS.
But basically agree with @herstein.jacob
Agree, confirmatory test should be antibody differentiation while Ag/Ab is the screening test. (though I’ve lost the plot on these cards now haha)
