Extra Credit –  FUN MLS 413 related Extra Credit If the physician ordered 4 units of A positive blood on a patient that had an unexpected Anti-Fya and an unexpected Anti-Jka, how many donor units would need to be antigen typed to theoretically find 4 compatible donor units?  (Fya antigen is present in 65% of the donor population, while the Jka antigen is positive in 77%.) Round up any decimal to the next whole donor unit.

One unit of random donor platelets (RDPs) should increase the recipient’s platelet count by:

For Lana Kane, let’s imagine the antibody you selected has its corresponding antigen present at 45% in the donor population, how many donor units in the blood bank fridge will need to be antigen typed to find 3 units that are potentially antigen negative.  Round up any decimal to the next whole donor unit.

When disease testing the donor unit, what three tests do they run to screen for Hepatitis B specifically?

What would be the best choice for the positive control and negative control when performing antigen typing?

When selecting donor units for crossmatching following the guidelines discussed in lecture, which of the following would be the proper ABO group selection order (best choices in order from 1st – 4th) for a 25-year-old pregnant female typing A negative?

If an autologous collection unit is ordered on a 31 Kilogram (68 pound) child, how much anticoagulant must be removed from the bag before filling it with autologous blood?  (So, what is the “amount of anticoagulant to be removed”?)  

How many vials of Rho(D) Immune Globulin (or RhIg) would need to be given to an Rh-negative mother if 55 mL of Rh positive fetal cells were detected in her maternal circulation?

If a patient has unknown coagulation problems, which type of unit would be the best choice for them?

If an A Positive recipient has previously never received blood or blood products,what would be the expected reaction in the crossmatch tube at the immediate spin (IS) phase with an O Negative Donor Unit?
