Top 10 Questions for Histology Specialist Interview

1. Walk me through your typical process for preparing a histological slide.

• Collect tissue samples and fix them in appropriate solution.
• Process the tissue samples through dehydration, clearing, and embedding.
• Cut thin sections using a microtome.
• Stain the sections with specific dyes to highlight different tissue components.
• Mount the stained sections on slides and cover them with coverslips.

2. What are the different types of fixatives you use and what are their advantages and disadvantages?

Chemical fixatives

• Formalin: Most commonly used; good for preserving overall tissue structure.
• Glutaraldehyde: Excellent for preserving fine details and ultrastructure.
• Alcohol: Rapidly fixes tissues, but may cause shrinkage and hardening.

Physical fixatives

• Heat: Quick and easy, but can damage delicate tissues.
• Cold: Preserves tissues by freezing; may cause ice crystals to form.

3. How do you optimize tissue fixation for specific antigens or epitopes?

Use appropriate fixatives and methods based on the target antigens or epitopes:

• Consider factors such as antigen size, location, and sensitivity.
• Use crosslinking fixatives (eg. glutaraldehyde) for small antigens.
• Use antigen retrieval techniques (eg. heat or enzymatic digestion) to unmask antigens after fixation.

4. What are the principles of tissue processing and embedding?

• Dehydration: Removing water from the tissue using graded series of alcohol.
• Clearing: Replacing alcohol with a clearing agent (eg. xylene) to make the tissue transparent.
• Embedding: Infiltrating and surrounding the tissue with a solid medium (eg. paraffin wax) to support it during sectioning.

5. How do you select the appropriate staining technique for a specific histological examination?

Consider the:

• Tissue: Type and condition of the tissue.
• Target: Specific components or structures to be visualized.
• Diagnostic purpose: Information needed from the staining.

6. What quality control measures do you implement in your histology laboratory?

• Tissue sampling: Ensure proper collection and preservation of tissues.
• Processing: Monitor and calibrate equipment, follow standardized protocols.
• Staining: Use standardized staining protocols, perform internal and external quality controls.
• Slide preparation: Check for proper section thickness and staining intensity.
• Interpretation: Regular review and quality assessment by experienced histologists.

7. How do you handle and interpret immunohistochemistry results?

• Control tissues: Use positive and negative controls to validate staining.
• Interpretation: Assess the intensity and localization of staining to determine antigen expression.
• Optimization: Troubleshoot and optimize staining protocols as needed.

8. What experience do you have in using molecular techniques for histological analysis, such as in situ hybridization or immunofluorescence?

• Describe experience in performing ISH or IF techniques.
• Highlight proficiency in probe or antibody selection, hybridization/incubation conditions, and imaging techniques.

9. How do you ensure the accuracy and reliability of your histological reports?

• Thorough examination: Carefully analyze slides and document findings.
• Collaboration: Consult with other pathologists or clinicians as needed for interpretation.
• Peer review: Have reports reviewed by colleagues for accuracy and consistency.

10. What professional development activities have you engaged in to stay current with advancements in histology?

• Continuing education courses: Attend workshops, conferences, or online training.
• Literature review: Stay abreast of the latest research and publications.
• Professional organizations: Participate in activities of pathology or histology societies.
