Frequently asked questions

What does a lab supervisor do?

A lab supervisor runs a lab shift or section. They allocate technicians to benches, check QC before results are released, review abnormal and critical results, decide on repeats and recollections, troubleshoot analysers, verify results in the LIS and keep daily records ready for audits.

What is the difference between a senior lab technician and a lab supervisor?

A senior lab technician is the most experienced person on the bench, running complex tests and guiding juniors. A lab supervisor runs the shift: allocating people, approving QC, authorizing results within their scope, handling escalations and answering to the lab manager for the section's output.

What qualifications are needed for a lab supervisor?

Employers look for a degree in medical laboratory technology, usually a BSc or MSc, and 5 to 8 years at the bench that include time as a senior technician. Smaller labs accept a DMLT with long experience. Knowledge of Westgard rules and ISO 15189 records is expected.
