Let’s be real for a second: nobody goes into medical laboratory science because they have a deep, burning passion for cleaning centrifuge buckets or checking the humidity levels in a storage room. We’re here for the diagnostics, the discovery, and the data.

Past Paper On Laboratory Maintenance For Revision

However, here is the cold, hard truth of the profession: a brilliant scientist with a poorly maintained analyzer is just a person generating expensive “garbage” data. Laboratory Maintenance is the backbone of quality assurance. If you can’t calibrate it, verify it, or fix it when the “Error 404” light starts blinking, the lab grinds to a halt.
Because this subject can feel a bit “dry” compared to hematology or microbiology, it’s easy to push it to the back of your study pile. But examiners love it because it tests your real-world readiness. To help you get ahead, we’ve put together a strategy and a resource to make your revision painless.

Lab Maintenance Q&A: Real Questions, Real Answers
Use these common exam topics to gauge how much of the “technical” side of the lab you’ve actually absorbed.
1. What is the difference between “Preventative Maintenance” and “Corrective Maintenance”?
This is the most fundamental concept in the syllabus.
Preventative Maintenance (PM): These are the scheduled tasks—daily, weekly, or monthly—designed to stop a breakdown before it happens. Think of it like changing the oil in your car.
Corrective Maintenance: This is what happens after the “bang.” It’s the unscheduled repair of equipment that has already failed or is producing results outside of acceptable limits.
2. How do you verify the accuracy of a centrifuge?
You don’t just “trust” that it’s spinning at the right speed. In an exam, you’ll likely be asked about a Tachometer. This is an external device used to verify that the RPM (Revolutions Per Minute) displayed on the centrifuge matches the actual physical speed of the rotor.
3. Why is “Temperature Mapping” essential for lab refrigerators and incubators?
It’s not enough to have one thermometer in the middle of the fridge. Different shelves can have “hot spots” or “cold spots.” Mapping ensures that life-saving reagents or patient samples are kept at a consistent temperature throughout the entire unit, preventing degradation.
4. What are the three levels of “Water Quality” in a clinical lab?
Water isn’t just water in a lab setting.
Type I: The purest. Used for ultra-sensitive tests like HPLC or trace element analysis.
Type II: Used for most general laboratory tests and reagent preparation.
Type III: Used for rinsing glassware or feeding autoclaves.
5. How often should a micropipette be calibrated?
While institutional policies vary, standard revision answers usually point to a six-month or annual cycle, or whenever the pipette has been dropped or cleaned internally. You should be familiar with the Gravimetric Method—weighing water to ensure the volume dispensed is accurate.
Strategy: How to Use This Past Paper
Don’t Memorize, Visualize: When you read a question about an autoclave’s “Validation,” picture yourself standing in front of the machine. Where does the biological indicator go? Why does the pressure matter?
The “Why” Behind the Error: If a question asks about a shift in a Levey-Jennings chart, don’t just say “maintenance is needed.” Identify if it’s a lamp failing, a clogged probe, or an old reagent.

Take the Stress Out of the Test
Laboratory maintenance isn’t just about passing a test; it’s about ensuring that when a doctor gets a result, they can trust it implicitly. By mastering these past papers, you’re proving you have the discipline required for the bench.
