1 Compatibility Testing

What is compatibility testing in blood banking?

• A process to ensure the greatest compatibility between the donor unit and the proposed recipient

• A process to determine the ABO and Rh grouping of the recipient and donor

• A process to screen for antibodies in the recipient and donor's serum

• A process to review the patient's post blood bank history and records

When did the first in vivo transfusion using human blood take place?

• 1628

• 1900

• 1907

• 1950

What is the purpose of antibody screening in compatibility testing?

• To detect hemolysins in the recipient's serum

• To determine the ABO and Rh grouping of the recipient and donor

• To ensure the greatest compatibility between the donor unit and the proposed recipient

• To review the patient's post blood bank history and records

When was the crossmatch procedure first attempted?

• 1628

• 1900

• 1907

• 1950

What is the purpose of the crossmatch procedure?

• To determine the ABO and Rh grouping of the recipient and donor

• To screen for antibodies in the recipient and donor's serum

• To ensure the greatest compatibility between the donor unit and the proposed recipient

• To mix the recipient's serum with red cells from the donor

• 1900

• 1907

• 1950

What is the immediate-spin crossmatch?

• A crossmatch performed in the absence of antibodies in the current antibody screen or the patient's past record

• A crossmatch performed using red cell products containing donor red cells

• A crossmatch performed using serum or plasma from the recipient with red cells from the donor

• A crossmatch performed under certain defined circumstances and the adoption of the computer crossmatch

When was the computer crossmatch proposed by the blood banking community?

What is the purpose of a crossmatch in blood banking?

• To determine the ABO and Rh grouping of the recipient and donor

• To screen for antibodies in the recipient and donor's serum

• To ensure the greatest compatibility between the donor unit and the proposed recipient
