Essential Interview Questions For Serology Technician
1. Describe the principles of hemagglutination and hemagglutination inhibition tests.
Answer:
- Hemagglutination (HA): A virus or bacteria binds to specific receptors on the surface of red blood cells, causing them to clump together.
- Hemagglutination Inhibition (HI): A specific antibody added to the reaction blocks the binding of the virus or bacteria to the red blood cells, inhibiting hemagglutination.
2. Explain the difference between direct and indirect immunofluorescence tests.
Antibody Labeling:
- Direct: Antibody specific to the antigen is directly labeled with a fluorescent dye.
- Indirect: A secondary antibody labeled with the fluorescent dye binds to the primary antibody bound to the antigen.
Applications:
- Direct: Detects antigens in fixed cell preparations (e.g., tissue sections).
- Indirect: Detects antigens in both fixed and live cells (e.g., flow cytometry).
3. Outline the steps involved in performing an ELISA (enzyme-linked immunosorbent assay).
Answer:
- Coat wells with specific antigen or antibody.
- Incubate with sample containing antibody or antigen.
- Wash away unbound material.
- Incubate with enzyme-linked secondary antibody.
- Add substrate for enzyme, resulting in color change.
- Measure color intensity to determine antibody or antigen concentration.
4. Describe the principles and applications of Western blotting.
Answer:
- Principles: Separates proteins by electrophoresis, transfers them to a membrane, and detects specific proteins using antibodies.
- Applications: Identifying proteins, studying protein expression, detecting antibodies in patient samples.
5. Discuss the role of quality control measures in serological testing.
Answer:
- Ensure accuracy and reliability of results.
- Involve using controls (positive, negative, known values) to verify test performance.
- Monitor variables (e.g., temperature, reagents) and document results.
- Follow established protocols and guidelines.
6. Explain the principles of complement fixation tests and their use in diagnosis.
Answer:
- Principles: Antigen-antibody reaction activates the complement cascade, leading to cell lysis.
- Use in Diagnosis: Detects specific antibodies in patient samples to confirm infections (e.g., syphilis, tuberculosis).
7. Describe the significance of cross-reactivity in serological tests and how it can be minimized.
Answer:
- Significance: Antibodies may bind to multiple antigens due to structural similarities, leading to false-positive results.
- Minimization: Use highly specific antibodies, absorb cross-reacting antibodies with unrelated antigens, and perform confirmatory tests.
8. Explain the importance of titer determination in serological testing.
Answer:
- Determines the concentration of antibodies or antigens in a sample.
- Useful for monitoring immune responses, assessing disease activity, and determining protective immunity.
9. Discuss the principles of multiplex serological assays and their advantages.
Answer:
- Principles: Simultaneous detection of multiple antigens or antibodies using a single assay.
- Advantages: Faster, more efficient, cost-effective, and provides a comprehensive profile.
10. Explain the ethical considerations related to serological testing.
Answer:
- Confidentiality and privacy of patient information.
- Informed consent before testing.
- Accurate and reliable test results.
- Proper interpretation and reporting of results.
- Compliance with regulatory guidelines.
