This Rh Terminology defined the five common Rh antigens and postulated that the

antigens of the system were produced by three closely linked genes (D/d, C/c, and

E/e):

• Fischer-Race

• Rosenfield and Coworkers

• Weiner

• ISBT

In order for an individual to express Leb antigen on their red blood cells, they must have inherited which gene?

• Le

• Se  

• H

• All of the above

Why must there be alpha designations in the Rosenfield system?

• •Nomenclature applies to other blood group systems besides Rh.

• •Rosenfield nomenclature is only used in the Rh blood system.

• •Weiner and Fisher-Race use alpha designations.

• None of the above

The Del phenotype is most commonly found in individuals of which ethnicity?

• Asian

• Whites

• Native American

• African

What protocol is put in place to validate Rh testing when high-protein reagents are used, especially when the patient types as an AB-positive?

• Wash cells before testing  

• Run a control with Rh test

• Add LISS to test system

• Use only saline reactive anti-D

What does the term exalted D refer to?

• Deletion of the D antigen

• Stronger expression of Cc antigens when D is missing

• •Stronger expression of Ee antigens when D is missing

• Stronger expression of D antigens when Cc and Ee are missing

The biochemical structure of the Rh antigens is a nonglycosylated protein, meaning:

• •lipids are not attached to protein structure.

• •carbohydrates are not attached to protein structure.

• glucose is attached to protein

• glycerol is attached to protein.

Rh-immune globulin is effective is preventing which type of hemolytic disease of the newborn (HDN)?

• Anti-c

• Anti-E  

• Anti-D

• Anti-C

All of the following are consistent with International Society of Blood Transfusion (ISBT) terminology except:

• •A six-digit number specifies each blood group antigen.

• •004 represents Rh group.

• D is written as "RH1."

• All genes are written in bold print.

All of the following may occur following an Rh-mediated hemolytic transfusion reaction except:

• elevated fever.

• increased bilirubin.

• •intravascular hemolysis.

• positive DAT.
