Most Repeated Lab Technician Interview Questions

Listed below are Medical Lab Technician interview questions and answers for both new and experienced individuals seeking their ideal job:

1. Explain What is Dynamic Range?

Answer: It is defined as the range across which there is a link between test response and analyte concentration.

2. What Are the Different Techniques for Placing Samples in a Microscope?

Answer: Various approaches for placing samples under the microscope are:

  • Dry Mount, place a specimen piece with a coverslip over a sample.
  • Wet mount, samples are placed beneath various liquid mediums such as glycerin, water, brine, and water.
  • Smear slides, in this procedure, the sample is smeared over the slide, and then another slide is placed on top of it without generating bubbles.
  • Squash slides, in this approach, lens tissue is put over the wet mount, which removes superfluous water.
  • Staining the specimen is stained with iodine, methylene blue, and crystal violet.

3. What Are Different Sterilization Methods Used in the Laboratory?

Answer: The most prominent methods of sterilizing used in laboratories are:

  • In dry heat, a specimen containing bacteria is subjected to high temperatures.
  • Wet heat pressurized steam is used to kill germs, such as in an autoclave, which is a pressure cooker that creates steam.
  • Filtration is utilized in situations when filters as fine as 0.2um are required.
  • Radiation UV has low penetration, making it typically safe to use, while it is less efficient against X-rays and gamma rays. X-rays and gamma rays are employed only for specific purposes.
  • Solvents such as ethanol and isopropanol kill microbial cells but not spores.

4. Explain What is the Difference Between Sterilization and Disinfection?

Answer:

  • Sterilization refers to the full sterilization of all germs present on the surgical instrument.
  • Disinfection is the process of lowering the total number of microorganisms to below the risk level.

5. Explain What is Gas Sterilization?

Answer: Gas sterilization uses chemicals such as ethylene oxide and a combination based on the substance to sterilize substances.

They are very flammable and potentially explosive in nature, hence they are combined with inert gasses to minimize their explosive properties.

6. What Are the Factors on Which the Gas Sterilization Depends on?

Answer: Gas sterilization is based on elements such as:

  • Concentration of gas.
  • Temperature.
  • Nature of the burden.
  • Humidity.
  • Time of Exposure.

7. Explain What Clinical Lab Audit is and What Are the Areas You Can Do Clinical Audit?

Answer: A clinical lab audit is conducted to ensure that the lab is maintained and operated at a standard level. Clinical auditing covers the following areas:

  • Specimens To verify the patient registration and see if the specimen was received on time.
  • The turnaround time Check whether the specimen was tested and returned on time, and if it was delayed, how to improve it.
  • GLP To determine whether the test methods used adhere to the established protocols.
  • Purchasing equipment, reagents, and other lab devices.
  • Laboratory reports, check whether they are exact and clear, and search for any areas for improvement.
  • Reagent and sample storage.
  • Safety policies and procedures The use of harmful drugs should be audited, and every laboratory accident should be documented.

8. Explain What is Laboratory Centrifuges?

Answer: The laboratory centrifuge serves mainly to examine liquids and compounds for clinical trials. This gadget uses centrifugal force to separate liquids from the primary sample or mixture.

9. Explain What is Supernatant?

Answer: When the sample is rotated in a centrifuge, it separates the mixture based on density. The supernatant is the upper layer of a sample after it has been centrifuged.

10. What Are the Steps You Can Take to Avoid Imbalance in Centrifuge?

Answer: To prevent an imbalance in the centrifuge:

  • The centrifuge rotor’s loading is balanced.
  • An even number of tubes should be loaded facing one another or in the opposite direction.
  • When an odd number of tubes are filled, make careful to make it even by adding one more tube with an identical amount of water as the sample tube.

11. What is Blank?

Answer: The blank phrase refers to a sample tube that does not contain the analyte.

12. Explain What is Calibration Curve?

Answer: The calibration curve represents the connection between various analyte concentrations in a suitable solvent or matrix and the instrument’s signal response.

13. Explain What is Co-chromatography?

Answer: Co-chromatography is a method for detecting an unknown drug by comparing the chromatic comparison to a recognized compound.

14. What Do You Mean by a Confirmatory Test?

Answer: A second test, often known as an alternate chemical approach, is used to identify drugs or metabolites in a sample without ambiguity.

15. Explain What is a Positive Control?

Answer: A positive control is a specimen that contains the analyte at a concentration greater than a specified limit.

16. What Are the Responsibilities of Laboratory Technician?

Answer: The responsibilities of clinical lab technicians vary depending on the department to which they are assigned, but typically include:

  • Scanning the specimen
  • Wide range of tests
  • Conducting complicated analysis.
  • Examine blood cells using a microscope
  • Use pricey chemicals wisely.
  • Maintaining and monitoring various equipment.
  • Checking contamination in chemicals at regular intervals

17. Explain What is Glp?

Answer: GLP indicates Good Laboratory Practice. It is a framework or pattern that guides research planning, execution, monitoring, recording, reporting, and archiving.

18. Explain Why Glp is Followed in the Lab?

Answer: They are:

  • It helps to minimize the cost to industry and governments by minimizing redundant testing.
  • This is useful to recreate a study from recorded data and information.
  • Following the GLP standard reduces the probability of error caused by people.
  • It helps product registration and ensures that data is suitable for regulatory bodies.

19. What Are the Common Errors Done by Technician While Handling Pipette?

Answer: They include:

  • Working too fast.
  • Pipetting at an incorrect angle.
  • Using improper pipette tips
  • Tip wiping repeatedly.
  • Choosing the improper pipetting mode
  • Failure to moisten the pipette tip
  • Disregarding temperature – temperature equilibrium

20. Why Pipetting Training is Crucial for Clinical Technicians?

Answer: Proper pipette training always helps to reduce the danger of volume variability produced by operators; also, a small proportion of the change in pipetting can provide an incorrect result.

21. Define What is Aliquot?

Answer: An aliquot is a known quantity of homogeneous material used to reduce sampling error. It is typically employed when the fractional component is an exact divisor of the whole.
