Antibody screening of the recipient is performed as a component of compatibility testing to detect: -
Answers red cell alloantibodies
Antibodies detected in the immediate spin crossmatch are usually of which of the following
immunoglobulin classes - Answers IgM
Select the correct statement regarding the collection of a blood sample for compatibility testing -
Answers the sample must be labeled at bedside
A patient was admitted to the hospital with acute bleeding. Anti-E was detected in the patient's serum.
Four E-negative units of blood were crossmatched for the patient. The units were compatible at
immediate spin and following the antiglobulin test. After the antiglobulin test was performed, IgG-
sensitized red cells gave a 2+ agglutination reaction. The proper interpretation of this 2+ agglutination
reaction is the - Answers antihuman globulin washing procedures was adequate (Check Cells Worked)
Which of the following tests is not included in routing compatibility testing - Answers Direct antiglobulin
test (DAT)
What are the two components of the major crossmatch? (What is matched against what?) - Answers
Recipient Serum; Donor Red Cells
A group O patient was crossmatched with group B red blood cells. What phase of the crossmatch will
first detect this incompatibility - Answers Immediate spin
Compatibility procedures will address all of the following except to - Answers prevent formation of all
red cell antibodies
Compatibility procedures will address all of the following - Answers prevent life-threatening transfusion
reactions;
maximize in vivo survival rate of red cells; and
check ABO compatibility.
A recipient phenotypes as group O with the following Rh phenotype: D+C+c-E+e+.
If this recipient is transfused with red blood cells from six random group O D-positive donors, what Rh
alloantibody could this patient produce as a result of transfusion - Answers anti-c
