Top 10 Questions for Histology Technician Interview

1. Describe the steps involved in processing a tissue sample for histological examination.

• Grossing: Examine and trim the tissue to select representative areas for examination.
• Fixation: Preserve the tissue in a chemical solution (e.g., formalin) to maintain its structure.
• Dehydration: Remove water from the tissue using increasing concentrations of alcohol.
• Clearing: Replace the alcohol with a solvent (e.g., xylene) to dissolve fat and wax.
• Embedding: Infiltrate the tissue with paraffin or other embedding medium to provide support.
• Sectioning: Cut thin sections of the embedded tissue using a microtome.
• Staining: Apply dyes to highlight specific structures within the tissue.
• Mounting: Attach the stained sections to glass slides.

2. Explain the difference between hematoxylin and eosin staining.

Hematoxylin staining

• Basic dye that stains nuclei blue.
• Highlights DNA and chromatin.

Eosin staining

• Acidic dye that stains cytoplasm and extracellular matrix pink.
• Highlights proteins, collagen, and muscle fibers.

3. What quality control measures are important in histology?

• Ensuring proper tissue collection and fixation.
• Calibrating equipment (e.g., microtome, staining equipment).
• Using standardized staining protocols.
• Monitoring reagent stability and expiration dates.
• Performing regular proficiency testing.
• Maintaining documentation of all processing steps.

4. What are some common artifacts that can occur in histology slides and how can they be avoided?

• Crumbling: Avoid over-fixation or dehydration.
• Tearing: Use sharp knives and handle sections carefully.
• Wrinkling: Ensure proper flattening during mounting.
• Bubbles: Degas solutions and use vacuum during tissue processing.
• Uneven staining: Check reagent concentrations and staining times.

5. How do you troubleshoot common problems encountered in histology, such as poor staining or tissue damage?

• Poor staining: Verify reagent concentrations, staining times, and tissue thickness.
• Tissue damage: Check fixative concentration, microtome settings, and handling techniques.
• Bubbles: Degas solutions, optimize vacuum settings, and use spin down steps.

6. What are the safety precautions to observe when working in a histology laboratory?

• Wear appropriate personal protective equipment (PPE).
• Handle chemicals with care and dispose of waste properly.
• Maintain cleanliness and organization in the work area.
• Follow established laboratory protocols and safety manuals.
• Report any accidents or potential hazards immediately.

7. Explain the role of a histology technician in supporting research or clinical diagnosis.

• Research: Prepare slides for microscopy studies, analyze tissue samples, and provide data.
• Clinical diagnosis: Process biopsies, identify pathological changes, and assist in diagnosing diseases.
• Communication: Collaborate with pathologists, researchers, and other healthcare professionals.
• Quality assurance: Ensure the accuracy and reliability of histology results.

8. How do you stay updated on the latest advances and techniques in histology?

• Attend conferences and workshops.
• Read scientific journals and research articles.
• Seek training and certification opportunities.
• Participate in online forums and discussion groups.

9. What is your approach to handling complex or challenging histology cases?

• Review the case history and clinical information.
• Collaborate with pathologists and other experts.
• Utilize special staining techniques or immunohistochemistry as needed.
• Document all findings and provide a detailed report.

10. What are the ethical considerations in histology, and how do you ensure patient confidentiality?

• Obtain informed consent for tissue collection.
• Handle patient data with confidentiality and privacy.
• Report any ethical concerns or safety issues to the appropriate authorities.
