If a false-positive reaction was suspected with anti-D in the forward grouping due to the presence of a cold autoantibody, which of the following would show reactivity?

All of the following antibodies are clinically significant except:

You have determined antibody specificity based on ruling out using panel cells that did not react. Explain how you have ruled in suspected antibody(ies) in this case. Is there additional testing that needs to be done to reach a conclusion?

The process of removing antibody from serum by combining a serum sample with appropriate red blood cells under optimal conditions is called:

A 28-year old male police officer was brought to the emergency room for gunshot wounds and 4 units of RBCs were ordered for emergency surgery.  The following results were obtained:   ABO Grouping Rh Typing Weak D Testing     Forward Reverse Patient cells with AHG CC   Patient cells with Patient plasma with   Anti-A Anti-B Anti-A,B A1 B A2 Anti-D D Control Weak D Weak D Control Weak D Weak D Control   Patient 00123 0 0   4+ 3+   very weak 0 1+ 0   √   The antibody screen is positive and the technician proceeds with a panel.  The panel conclusion is the presence of anti-D antibody but anti-E cannot be ruled out. The AABB standards state that persons who test as weak D positive may receive Rh positive blood. In this case, would the policy be honored? Identify how the technician should prepare units for transfusion.   Explain the ABO/Rh and antibody panel results. Provide justification for your decision and next steps.

A male patient was seen in the emergency room with an acute bleed. The recommendation from the blood supplier is to give O-positive RBCs as uncrossmatched blood. This patient has already been exposed to Rh-positive blood after a previous accident. What is a possible outcome?

What alternative type can be given to an O-positive person when group O blood is not available?

The most important key to effective word choice is what?
