We are Meditech C/S and have worksheets for antigen typing which include the Pos and Neg controls. First we order an antigen "group" test on each unit. The "group" includes the "T" tests for reaction, check cell and result. We create the worksheet that calls all antigen testing on to it. We record the reactions in the computor and verify the worksheet which edits the units accordingly. Custom labels are then printed that include the unit#, unit ABORH, date, and the antigen-POS/NEG.
