, Blood Banking Exam Questions 2026/2027
SECTION A: DONOR SELECTION AND BLOOD COLLECTION (Questions 1-10)
Question 1
Based on the evaluation of hematocrit (Hct), blood pressure (BP), pulse, age, and gender, which
individual represents an acceptable allogeneic donor?
A) Hct 38%, BP 95/65, Temp 99.6°F, Pulse 72, Age 72, Female
B) Hct 41%, BP 110/80, Temp 99.4°F, Pulse 65, Age 65, Male
C) Hct 44%, BP 140/90, Temp 98.6°F, Pulse 85, Age 55, Female
D) Hct 36%, BP 120/75, Temp 99.8°F, Pulse 60, Age 45, Male
Answer: B
Explanation: Acceptable allogeneic donors must meet specific criteria including hematocrit
≥38% for females and ≥39% for males, blood pressure within acceptable ranges (systolic 90-180
mmHg, diastolic 50-100 mmHg), temperature ≤99.5°F (37.5°C), pulse between 50-100 beats per
minute, and age within regulatory guidelines. Option B demonstrates all parameters within
acceptable ranges.
Question 2
What is considered the definition of allogeneic blood?
A) Blood collected from a patient for their own future use
B) Blood donated by a donor for a recipient other than the donor
C) Blood that has been processed and fractionated into components
D) Blood collected from family members specifically for a patient
Answer: B
Explanation: Allogeneic blood refers to blood that is donated by one individual for transfusion
to another individual who is not the donor. This is distinguished from autologous blood (donated
for one's own use) and directed donations (from a specific donor to a specific recipient, though
still considered allogeneic). The term encompasses the vast majority of blood donations in the
healthcare system.
,Question 3
A unit of RBCs that has been issued and returned to the blood bank can be returned to inventory
and is acceptable to use under which circumstance?
A) The unit was stored at room temperature for 45 minutes in the operating room
B) The unit was transported to a patient's bedside but not removed from the transport container
C) The unit was not transfused but stored in a temperature-controlled remote refrigerator in the
operating room for 2 hours
D) The unit was kept at 4°C in a portable cooler for 3 hours
Answer: C
Explanation: According to current blood banking standards, a unit of RBCs that has been issued
but not transfused may be returned to inventory if it has been maintained at the appropriate
storage temperature (1-6°C) throughout the period of issue. Storage in a temperature-controlled
remote refrigerator in the operating room ensures temperature maintenance. The unit must not
have been exposed to temperatures outside the acceptable range, and the integrity of the unit
must be maintained.
Question 4
What is the shelf-life of whole blood collected in CPDA-1?
A) 21 days
B) 28 days
C) 35 days
D) 42 days
Answer: C
Explanation: Whole blood collected in CPDA-1 (Citrate Phosphate Dextrose Adenine-1) has a
shelf-life of 35 days when stored at 1-6°C. The adenine in the preservative solution supports
ATP regeneration in red cells, extending the storage period compared to CPD (21 days) or CP2D
(21 days). Current standards for CPDA-1 whole blood and red cell components specify 35-day
storage at the proper temperature.
, Question 5
What is the required storage temperature for RBC components?
A) 1-6°C
B) 2-8°C
C) 4-10°C
D) 20-24°C
Answer: A
Explanation: Red blood cell components must be stored at temperatures between 1°C and 6°C.
This temperature range maintains red cell viability and function while minimizing bacterial
growth and metabolic activity. Storage outside this range can compromise red cell integrity,
reduce post-transfusion survival, and increase the risk of bacterial contamination.
Question 6
A potential donor reports a history of travel to a malaria-endemic region within the past 12
months. According to current FDA guidance, what is the appropriate deferral period?
A) No deferral if asymptomatic
B) 3 months
C) 12 months
D) Permanent deferral
Answer: B
Explanation: According to current FDA guidance (updated in 2024), donors who have traveled
to malaria-endemic areas are deferred for 3 months following their return. This represents a
significant change from the previous 12-month deferral period, reflecting improved testing
capabilities and risk assessment. The deferral applies regardless of symptoms, as malaria can be
transmitted by asymptomatic carriers.
Question 7
A 70-year-old male presents for blood donation. His hemoglobin is 13.2 g/dL, blood pressure is
145/85 mmHg, and pulse is 72 bpm. Which of the following is correct regarding his eligibility?
A) He is ineligible due to age
B) He is eligible as all parameters are within acceptable ranges
C) He is ineligible due to elevated blood pressure
