TOPIC 1: SERUM PROTEIN ELECTROPHORESIS
4 Questions • 6.7% of Exam • Focuses on the interpretation and follow-up of serum protein electrophoresis results.
QUESTION 1
A peripheral blood smear shows numerous immature granulocytes. Which stain is
most useful to identify a possible leukemoid reaction versus chronic myelogenous
leukemia?
Answer: LAP (leukocyte alkaline phosphatase)
Rationale: LAP activity differentiates reactive neutrophils (high) from CML (low).
QUESTION 2
Which of the following statements about the WHO International Standard for anti-HBs is
correct?
Answer: It is used to calibrate quantitative assays worldwide.
Rationale: The WHO standard provides a universal reference for anti-HBs quantitation.

QUESTION 3
A patient's serum protein electrophoresis shows a sharp narrow spike in the γ region.
Which follow-up test is most appropriate?
Answer: Immunofixation electrophoresis.
Rationale: Immunofixation identifies the monoclonal protein responsible for the spike.
QUESTION 4
A lab adopts a new reagent for serum protein electrophoresis that contains a
proprietary dye. What documentation is required before clinical use?
Answer: Internal validation report and FDA clearance.
Rationale: Verification of performance and regulatory clearance are mandatory before implementation.
TOPIC 2: H. PYLORI TESTING
4 Questions • 6.7% of Exam • Covers the stability and handling requirements for H. pylori antigen testing specimens.
QUESTION 5
A lab receives a stool specimen for H. pylori antigen testing that has been stored at 4
°C for 72
hours. What is the most appropriate action?
Answer: Reject the specimen and request a new sample.
Rationale: H. pylori antigen stability declines after 48 hours at 4 °C, requiring a fresh specimen.
QUESTION 6
Which of the following best describes the three steps of a standard PCR cycle?
Answer: Denaturation, annealing, extension.
Rationale: PCR cycles consist of denaturation, primer annealing, and DNA polymerase-mediated extension.
