Blood Type
This blood type is the universal RBC donor.
What is O negative?
The reagent used to cross link antibody coated red cells together to cause macroscopic agglutination.
What is AHG?
The length of time that antibodies are honored for.
What is: FOREVER! LIFE!
This type of crossmatch is used by a computer system that can determine if the blood types are ABO compatible.
What is an electronic crossmatch?
If a patient as Anti-E, you will need to find a unit of blood that is negative for this antigen
What is E?
The number of days that a blood bank specimen is good for.
What is 3 days?
These are added to a negative tube screen to serve as a quality control.
What are check cells?
This test is performed alongside antibody screens/panels and is run through AHG.
What is an autocontrol?
Type of crossmatch used for a patient that does not have an antibody.
What is an immediate spin crossmatch?
If a patient is C+, you can assume that they will not make this antibody.
What is Anti-C?
This reaction grading is described as a clear background with multiple large clumps.
What is 3+?
This reagent lowers zeta potential and allows antibodies to attach more efficiently.
What is LISS?
This type of antibody is caused by pregnancy, transfusion, or transplant.
(Ex: Alloantibody or Autoantibody)
What is an Alloantibody?
This type of crossmatch is used for a patient that has an antibody.
What is an AHG crossmatch?
Type of cell used to perform positive QC for antisera.
What is Heterozygous (single dose)?
This test needs to be performed in order to result a patient as AB positive.
What is an autocontrol?
This reagent is added after washing 3x.
What is AHG?
The effect in which there is a difference in antibody strength depending on the quantity of antigens present on the red blood cells.
What is the dosage effect?
An AHG crossmatch that has a positive reaction means that the unit of blood is considered __________ with the patient.
What is incompatible?
True or False: If a patient does not have an antibody, you still need to perform antigen typing on donor units
What is False?
The blood type known as the universal PLASMA donor.
What is AB?
The next step to perform after you find a positive antibody screen.
What is a panel/antibody ID?
The type of cell BEST used to rule out an antibody.
What is Homozygous (double dose)?
Crossmatch used when a patient has a historical antibody, but a current negative antibody screen.
What is an AHG crossmatch?
A patient's antigen typing has been determined to be:
E-, e-, C+, c-, K+, k-, Jka-, Jkb+
List the antibodies that the patient cannot form.
What are Anti-C, Anti-K, and Anti-Jkb?
