QUESTIONS AND ANSWERS
Plasma neutralization is best used to verify which of the following
antibodies?
a anti-Lub
b anti-M
c anti-Ch/Rg
d anti-V
c anti-Ch/Rg
b anti-Leb is confirmed because the tubes with LE substance are negative
To confirm the specificity of anti-Leb, an inhibition study using LE substance is
performed with the results shown in this table. What conclusion can be made
from these results?
a second antibody is suspected due to the positive control
b anti-Leb is confirmed because the tubes with LE substance are negative
,c anti-Leb is not confirmed because the tubes with LE substance are negative
d anti-Leb cannot be confirmed because the saline control is positive
d group O secretor
Which is the correct interpretation of this saliva neutralization testing?
a group A secretor
b group B secretor
c group AB secretor
d group O secretor
Antibody identification results performed using solid phase technology
resulted in undetermined results as all common alloantibodies are
excluded. What additional testing could determine if a cold reactive
antibody is responsible for the questionable results?
a DTT-treat patient serum and repeat testing
b test at IS, room temperature (RT) and 37°C with manual tube testing
c repeat all testing using column agglutination technology
d repeat all testing and add albumin as an enhancement media
b test at IS, room temperature (RT) and 37°C with manual tube testing
An antibody screen performed using solid phase technology revealed a
diffuse layer of red blood cells across the entire well. These results indicate:
a a positive reaction
b a negative reaction
c serum was not added
d red cells have a positive direct antiglobulin test
a a positive reaction
Which of the following genes on chromosome 1 is made up of 2 exons,
leading to the expression of the FY glycoprotein and its antigens?
,a DAF
b FYAB
c FY
d ACKR1
d ACKR1
Which of the following is useful for removing IgG from red blood cells with
a positive direct antiglobulin test (DAT) to perform a phenotype?
a bromelin
b chloroquine
c low ionic strength saline (LISS)
d dithiothreitol (DTT)
b chloroquine
A patient's serum contains a mixture of antibodies. One of the antibodies is
identified as anti-D Anti-Jkª, anti-Fya and possibly another antibody are
present. What technique(s) may be helpful to identify the other
antibody(ies)?
a enzyme panel; select cell panel
b thiol reagents
c lowering the pH and increasing the incubation time
d using albumin as an enhancement media in combination with selective
adsorption
a enzyme panel; select cell panel
c Dolichos biflorus
A sample gives the results shown in this table. Which lectin should be used first
to resolve this discrepancy?
, a Ulex europaeus
b Arachis hypogaea
c Dolichos biflorus
d Vicia graminea
d perform a warm autoadsorption
A donor who has just donated 2 units of Apheresis Red Blood Cells will be
deferred from further blood donation for a minimum of how many weeks?
a8
b 12
c 16
d 24
c 16
Which of the following infectious agents relies solely on donor questioning
to avoid transmission from transfused blood products?
a Trypanosoma cruzi
b Plasmodium falciparum
c HCV
d CMV
b Plasmodium falciparum
Which of the following practices at the time of blood collection helps
minimize bacterial contamination of platelet products?
a use of 18-gauge needle
b diversion pouch
c green soap scrub
d UV irradiation
b diversion pouch
