Precision behind every diagnosis

Medical laboratory technicians are essential to modern healthcare—performing diagnostic tests, analyzing samples, and supporting doctors in patient care. In the UAE, Saudi Arabia, and across the GCC, demand is rising for skilled lab technicians in hospitals, clinics, and diagnostic centers.

Here are 10 of the most common interview questions for lab technicians and how to answer them confidently.

1. Why did you choose a career in medical laboratory science?

“I’ve always had an interest in science and healthcare. Working behind the scenes to help diagnose and treat patients combines my passion for analysis with meaningful impact.”

2. What types of lab tests are you most experienced in?

“I’m experienced in hematology, microbiology, biochemistry, and immunology. I’ve also worked with PCR testing and have assisted with COVID-19 diagnostics during the pandemic.”

3. How do you ensure accuracy in test results?

“I double-check specimen labeling, calibrate equipment regularly, follow SOPs, and participate in quality control programs to ensure results are valid and reliable.”

4. How do you handle a sample that’s been mislabeled or contaminated?

“I immediately report the issue to the supervisor, reject the sample if needed, document the error, and request a new sample to avoid jeopardizing patient safety.”

5. What lab equipment are you comfortable using?

“I’m proficient with centrifuges, microscopes, spectrophotometers, automated analyzers, and blood gas machines. I also handle maintenance and troubleshooting when needed.”

6. How do you manage multiple tasks during a busy shift?

“Yes, I’ve used LIS platforms like Cerner and Meditech for tracking samples, logging results, and integrating reports with hospital records.”

9. Describe a time you caught an error before it impacted results

“While reviewing a CBC result, I noticed an abnormal value that didn’t match the clinical notes. I re-ran the sample and found a clot. Catching that prevented a misdiagnosis.”

10. Why should we hire you?
