Final answer:
The technician's observation of agglutination in both wells with anti-A and anti-B antibodies indicates the patient has an AB blood type, which is a normal and expected response for blood typing.
Step-by-step explanation:
In the scenario described, when a patient's blood sample agglutinates with both anti-A and anti-B antibodies, the technician has not made an error. This is a normal response for someone with the AB blood type. During blood typing, the presence of agglutination indicates that the patient's blood cells have reacted to the specific antibodies added to each well, providing information on which antigens are present on the surface of the blood cells.
The test typically run for the ROYAL BLUE tube is the complete blood count (CBC). This test provides information about the different types of cells in the blood, including red blood cells, white blood cells, and platelets. The anticoagulant used in the ROYAL BLUE tube is known as potassium EDTA, which prevents the blood from clotting. The tube is usually sent to the Hematology section of the laboratory for analysis.
