Term
Does anti-D show dosage?
Definition
No.
Term
Are Rh antibodies warm or cold reacting?
Definition
warm.
Term
Are Lewis antibodies warm or cold reacting?
Definition
Cold.
Term
Is anti-I warm or cold reacting?
Definition
cold.
Term
What is the minimum number of cells used in an antibody detection panel?
Definition
8
Term
Are anti-H antibodies IgM or IgG?
Definition
IgM.
Term
What kind of candy does the P1 penguin eat?
Definition
M & N's.
Term
Are anti-Kell antibodies warm or cold reacting?
Definition
warm.
Term
Are anti-S and anti-s antibodies warm or cold reacting?
Definition
warm.
Term
Can Rh antibodies show visible agglutination at 37 C?
Definition
Yes.
Term
Are anti-Duffy antibodies warm or cold reacting?
Definition
warm.
Term
Are anti-M antibodies warm or cold reacting?
Definition
They can be either one.
Term
Can Kell, Kidd, or Duffy antibodies show visible agglutination at 37 C?
Definition
No, they usually don't because they are IgG. AHG is needed to show agglutination.
Term
What is the incubation time without adding LISS?
Definition
One hour.
Term
Which AHG is more likely to detect clinically insignificant antibodies; polyspecific, or IgG?
Definition
polyspecific.
Term
What is the best phase of testing for detection of Rh, Kell, Kidd and Duffy antibodies?
Definition
AHG.
Term
Do Rh antibodies show dosage?
Definition
Yes, except for Anti-D, which does not show dosage.
Term
Do Kidd antibodies show dosage?
Definition
Yes.
Term
Do anti M and N antibodies show dosage?
Definition
Yes.
Term
Do Kidds, Kells and Duffy's show dosage?
Definition
Yes.
Term
What kind of antibodies show mixed-field agglutination?
Definition
anti-Sda and anti-Lua
Term
Are Kidd antibodies enhanced with enzyme treated cells?
Definition
yes.
Term
Are duffy antibodies enhanced with enzyme treated cells?
Definition
No, they are depressed/destroyed
Term
Kidds, Rh, Lewis, I and P1 are all enhanced by what?
Definition
enzymes.
Term
Are Lewis antigens enhanced or destroyed by enzymes?
Definition

Definition
destroyed.
Term
When choosing cells to QC the antisera, should you look for homozygous or heterozygous cells?
Definition
heterozygous.
Term
What are two possible causes for multiple strengths of reactions?
Definition
dosage or multiple antibodies.
Term
If you are choosing cells for a select cell panel, should you pick out homozygous or heterozygous cells for the antigen you're looking for?
Definition
homozygous.
