Exam 8: Blood Group Terminology and Common Blood Groups

It was discovered that a patient who was to receive two units of packed RBCs had an anti-Le^a circulating in his system. What would be the proper procedure?

What is the most common genetic combination in the Kell blood group system?

Enzymes destroy the antigens of which of the following blood groups?

What is the International Society of Blood Transfusion (ISBT) assignment for the antigen P²?

Anti-N will react stronger with which phenotype?

What is the ISBT designation for the Kell system?

A cold antibody panel was performed to help identify an antibody that reacted at room temperature. The results of the panel are as follows: A₁ cells = 0, A₂ cells = 2+, B cells = 3+, O adult cells = 4+, Cord O cells = 1+. This is consistent with which antibody?

The structures that carry the P antigens also carry which determinants?

At what phase of the antihuman globulin test will anti-Kell be detected?

What is the function of a GPB-GPA hybrid (anti-Lepore type)?

What is the most common Lutheran phenotype in the white population?

Persons who express the phenotype P₂ are at risk for developing anti-P₁ when handling what animal species?

What is the etiology of chronic granulomatous disease (CGD)?

What can be done to rule in anti-M when only M+N+ red blood cells are available?

Why does anti-Lu^a go undetected in routine testing?

P1 antigens:

Units that were positive for P² antigen had to be crossmatched with serum of a patient containing the corresponding antibody because of a short supply of blood. Which of the following crossmatch results would be considered acceptable for transfusion?

The Lu gene shares chromosome 19 with what other blood group gene?

Red blood cells were treated with ficin to help rule in anti-M from a panel study. Cells not treated reacted at 2+ at immediate spin and 1+ at 37°C. There was no reactivity in the Coombs phase. Ficin-treated cells demonstrated a reaction with patient serum containing anti-M.

Where are the Kidd antigens found?
