We set up the usual result codes for antigen typing Reaction Results... the standard 0, 1+, 2+, 3+,.....but added a few specific to antigen typing: 0/0 (negative IS/ negative 15 minRT incubation), 0/* ( negative AHG/ postive Coombs check), etc. We defined the result codes in our procedure manual. We feel we've documented the reactions adequately but really haven't had any inspector question it.
