Question

Quizplus · Accepted Answer

A mixed field reaction occurs when there is a mixture of two different populations of red blood cells in a single specimen. This can happen if a patient has received an emergency transfusion of group O red blood cells, which do not have A or B antigens on their surface. If the patient's own red blood cells have A or B antigens, they will still be present in the specimen along with the group O cells, resulting in a mixed field reaction. Among the given options, this scenario can only happen in a patient with group A blood receiving an emergency transfusion of group O cells (option C).
