In this example, anti-M can be identified as the possible antibody by looking at the patterns of reactivity. Reactions are only occurring at immediate spin, so this would not be considered a clinically significant antibody.
Clinically significant antibodies are usually IgG and react at 37°C and at the AHG phase.
IS = Immediate Spin; AHG = Antihuman Globulin Phase; CC = Check Cells; AC = Auto Control
