Confirm ABO compatibility
ABTest Card® is a device, from Diagast, for the confirmation of ABO compatibility between the patient and the blood unit to be transfused. Based on the M-TRAP® technology, it allows an easy and simple confirmation, safer for both user and patient.
The red blood cells tested, carrying an antigen, interact with the related antibodies, revealing a red spot (positive reaction). The red blood cells that do not carry the antigen do not interact with the antibodies and cross the membrane. The spot will appear light green or white (negative reaction).
If the red blood cells tested interact with the associated antibodies, the blood deposit remains. Red blood cells carry the desired antigens. It is a positive reaction.
If the red blood cells tested do not interact with the associated antibodies, the blood deposit disappears. Red blood cells do not carry the desired antigens. It is a negative reaction.
ABTest MULTI also offers a bedside test dedicated to emergency massive transfusions. This device allows to test once the patient to transfuse a maximum of 3 red blood cell (RBC) within 1 hour, allowing safety and traceability.
