The minimum requirement for a vehicle stop, with regard to a particular vehicle or driver is:​

Routine pre-transfusion testing consists of all of the following except:

The following results were obtained when testing a sample from a 20 year old, first time donor. What is the likely ABO group for this patient? Forward Type             Reverse Type anti-A        anti-B       anti-A1 lectin A1 cells B cells +/- 0 0 0 4+  

All of the following antibodies are clinically significant except:

You are the technical supervisor of the blood bank.  One of your techs suggests that it would be more cost effective to perform antibody screening on patients using commercially available pooled reagent red blood cells rather than a three-cell screen.  The tech reasons that the pooled reagent requires only one gel well for testing versus three wells for the typical screen cells.  This would mean cost savings!  Is it acceptable to use pooled screening cells for patient pre-transfusion testing?  Why or why not?

What results would be expected if the same panel were retested after enzyme treatment?

A type and screen is done on a 49-year-old woman who is scheduled for a hysterectomy in 1 week. Her blood type is A-positive, and her antibody screen was positive. What must be done before her surgery date?

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?

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 positive autocontrol in antibody detection procedures is usually indicative of:
