Exam 7: Other Red Cell Blood Group Systems, Human Leukocyte Antigens, and Platelet Antigens

MATCHING Match each characteristic with the appropriate blood group system.A selection may be used more than once. -Antigen has a higher frequency in females

Which condition is often associated with the presence of anti-I?

Antibodies to which of the following blood group system show dosage (i.e.,are stronger with homozygous expression of the antigen)?

MATCHING Match each characteristic with the appropriate blood group system.A selection may be used more than once. -Antigen of high incidence; its antibody can cause hemolytic transfusion reactions

Anti-Jsᵇ was identified in a patient scheduled for elective surgery later.What is the best approach to finding compatible blood?

Which of the following facts is not a characteristic of Kell system antibodies?

The mixed lymphocyte culture (MLC)is a procedure that has been used in HLA testing to determine:

Why have Lewis system antibodies not been implicated in hemolytic disease of the fetus and newborn?

K-positive donor red cells were mistakenly transfused to a recipient with anti-K.The patient's posttransfusion blood sample has a positive direct antiglobulin test with polyspecific antihuman globulin.The direct antiglobulin test is positive because anti-K is an __________ antibody that has sensitized the __________ cells in vivo.

MATCHING Match each characteristic with the appropriate blood group system.A selection may be used more than once. -Antibodies are sensitive to enzymes and have high-titer low-avidity characteristics
