A patient was admitted to the hospital with acute bleeding. Upon compatibility testing, the technician detected Anti-E in the patient’s serum.    Four E-negative units of blood were crossmatched for the patient. The units were compatible at immediate spin, 37 degrees, and after the AHG phase.   After the negative AHG phase, IgG-sensitized red cells (aka Coomb’s control cells or check cells) gave a 2+ agglutination reaction. As a technician you know that the 2+ reaction AFTER the addition of check cells means:

The direct antiglobulin test is positive because anti-K is an __________ antibody that has sensitized (attached to) the __________ cells in vivo.
