EXAM PREPARATION PACK 2026 KEY
CONCEPTS AND REVISION NOTES
◉ Leakproof solid plastic container ("sharps"). Answer: Where
should biohazardous needles and glass materials be disposed?
◉ No. Answer: A technologist in training noticed that the person
training her had some food and water stored in her reagent
refrigerator. Is this an acceptable practice?
◉ True. Answer: The Food and Drug Administration classifies blood
as a drug.
◉ False. Answer: Proper glove techniques require that gloves are
washed with soap after handling blood samples so they can be used
again.
◉ The original entry is neither obliterated nor deleted
The person making the correction dates and initals the change
The item to be corrected is crossed off with a single line. Answer:
What criteria apply to the correction of manual records?
,◉ Identify employees in need of retraining. Answer: What is the
purpose of competency assessment?
◉ AABB. Answer: What organization publishes the Technical
Manual, which is often used for principal guidelines in the blood
bank?
◉ Used to monitor accuracy and precision. Answer: What statement
does not apply to the definition of an SOP?
◉ Root-cause analysis. Answer: What term describes the process to
identify what factors contributed to the occurrence of a
nonconformance?
◉ valency. Answer: What term describes the number of antigen-
binding sites per molecule of antibody?
◉ lipid. Answer: What classification of molecules does not make a
good immunogenic substance?
◉ glycoprotein. Answer: What is the chemical composition of an
antibody?
,◉ positive. Answer: After performing a tube test, the supernatant of
the test was pinkish and the red cell button was small. How do you
interpret the result of this test?
◉ 1+. Answer: How would you grade an agglutination reaction if you
observe many small agglutinates in a background of free cells in tube
testing?
◉ commercial reagent red cells. Answer: To determine the presence
of a red cell antibody in a patient's sample, what is the source of
antigen?
◉ patient is group A. Answer: After addition of anti-A reagent to a
patient's red cell suspension, agglutination was observed. The result
with anti-B reagent was negative. What is the interpretation of this
patient's ABO typing?
◉ IgM. Answer: Anti-A from a type B individual is primarily what
class of immunoglobulin?
◉ Hemolysis and agglutination. Answer: Antigen and antibody
reactions may be detected by which of the following?
◉ Cell lysis
Enhanced cell clearance
, Neutrophil activation. Answer: How does complement activation
demonstrate within the body?
◉ IgM. Answer: Immunoglobulins that are the first to be produced in
response to infection are
◉ epitope. Answer: Select the term that describes the unique part of
the antigen that is recognized by a corresponding antibody.
◉ Plasma cell. Answer: What cells can produce antibodies?
◉ Positive result. Answer: What does hemolysis represent in an
antigen-antibody reaction?
◉ Sensitization. Answer: What is the first stage of an antigen-
antibody reaction?
◉ opsonins. Answer: What term describes molecules that bind to an
antigen to increase phagocytosis?
◉ On the red cell membrane. Answer: Where is the antigen located
in a hemagglutination test?
