This is the preferred donor for a whole-blood unit to a B-group patient.

What is an ABO-identical, B-group donor?

100

The phenotype that may appear when the C antigen is inherited trans to D, or when r' is paired with R1 or R0.

What is Weak D?

100

Although most malaria parasites would not be opposed to a blood cell host, this phenotype limits the attachment of P. knowlesi and P. vivax merozoites to the RBC membrane.

What is Fy(a-b-)?

100

Ficin and papain enhance these specific antigens.

What are Rh, Kidd, Lewis, P1, and I/i?

100

This titer is usually critical for anti-D and other Rh antibodies.

What is a titer of 16 or 32?

200

The mechanism for Group A with acquired B, or vice versa.

What are bacterial deacetylating enzymes?

200

This is the order from most to least common Rh genotypes in the Black population.

What is R0, r, R1, and R2?

200

A phenotype that demonstrates a genetic absence of the Kx antigen, weakening the Kell antigen in the process.

What is the McLeod phenotype?

200

The occurrence when screening is negative and cross-matching is positive.

What are antibodies towards low-frequency antigens?

200

This screening test involves detecting rosettes in the postpartum maternal specimen.

What is screening for fetomaternal hemorrhage?

300

If a patient has an amorph of L-fucosyltransferase, they would be classified as this.

What is the Bombay phenotype (hh)?

300

This blood group system is phenotypically similar to Rh, goes away with DTT, and antibodies against it react with D-pos and D-neg cells.

What is the LW blood group system?

300

The Kidd antibody's main reason for delayed hemolytic transfusion reaction.

What are evanescent antibodies?
300

The potentiator that is less sensitive than others, but also enhances cold autoantibodies.

What is LISS?

300

A change in OD within the middle zone of a Liley graph would indicate this.

What is moderate HDFN?
400

Following a series of incubations of test serum and RBCs, centrifugation, saline replacement, and another spin in the centrifuge, agglutination would be labeled as such.

What is true agglutination?

400

The genotype with the most D antigens.

What is R2R2?

400

The main cell antigen involved in IgG antibodies implicated in TRALI.

What are human neutrophil antigens?

400

An ABID uses a panel of cells from this source.

Commercially prepared, single donor Group O cells.

400

The most common causes of HDFN besides ABO and Rh.

What are anti-c and anti-K antibodies?

500

Although there are numerous rare subgroups of A type, Ael, Ax, and Abantu do not display this subgroup's mixed field reaction.

What is subgroup A3?
500

The inheritance of C or D concurrently produces this antigen, mimicking antibodies towards C and D antigens.

What are the G antigens?
500

The genetic inheritance of genes in a Le(a+b-) person.

What is FUT3 functional, FUT2 nonfunctional?

500

This antibody shows a characteristic orange and refractile microscopic pattern.

What is anti-Sda?

500

A cord blood may phenotype as this blood type due to intrauterine transfusions.

What is Group O, D-negative?
