Skill-Level Determiner Questions

1. Describe the process you follow when performing a complete blood count (CBC). What steps do you take to ensure accuracy?

This question tests the candidate’s familiarity with basic hematology testing and assesses their attention to detail, which is crucial for producing accurate and reliable results.

A good answer should include:

  • Outline the steps clearly, demonstrating knowledge of the procedure.
  • Mention quality control checks, such as using control samples.
  • Explain how to interpret common issues or flags that analyzers might report.
Sample Answer:

"When conducting a Complete Blood Count (CBC), I first confirm the patient’s identity and adhere to proper specimen collection protocols. I then prepare the automated analyzer, confirming its calibration and quality control status. 

Throughout the analysis, I watch for errors or abnormalities, addressing any issues such as clotting. Finally, I validate the results against historical data and reference ranges, and if necessary, conduct a peripheral blood smear for further examination."

2. What precautions do you take to avoid contamination or degradation of specimens during collection and handling?

This question assesses a candidate’s awareness of proper specimen handling procedures and commitment to maintaining the highest laboratory practice standards.

A good answer should include:

  • Discuss the use of appropriate protective equipment and sterile techniques.
  • Explain the handling of specimens in a timely manner and proper storage conditions.

Sample Answer:

"To prevent contamination or degradation, I always wear appropriate PPE such as gloves and lab coats and use sterilized collection tools. I handle specimens promptly to avoid prolonged exposure to environmental factors that can affect their integrity. 

For example, blood samples for certain analytes should be kept at room temperature and processed quickly, while others need to be chilled. I ensure proper labeling to avoid mix-ups and store each specimen according to its specific requirements, following our lab's SOPs and the latest OSHA guidelines."

3. Describe the procedure for labeling, storing, and transporting specimens in the laboratory. How does this maintain specimen integrity?

This question gauges a candidate’s understanding of the logistical aspects of specimen management and their ability to prevent pre-analytical errors.

A good answer should include:

  • Illustrate the importance of correct labeling practices.
  • Hone in on specific storage conditions for different types of specimens.
  • Highlight the use of secure containers for transport to prevent spills or cross-contamination.
Sample Answer:

"The process begins with careful labeling at the point of collection, where I make sure all specimens are clearly marked with patient identifiers, the type of specimen, and the time of collection. 

In storage, I adhere to the required temperature conditions and timelines, whether it's refrigeration or freezing, to maintain specimen viability. 

For transport, I use sealed biohazard bags and properly secured, durable containers to prevent accidents, and I personally ensure that each specimen is logged into our tracking system for accountability and traceability."

4. How do you ensure the integrity of a specimen from collection to processing?

This question examines a candidate’s ability to adhere to protocols that prevent pre-analytical errors, which are vital for reliable laboratory outcomes.
