The questions to expect
Internal QC has failed on an analyser mid-run. Talk us through exactly what you do.
Stop reporting, quarantine results since last good QC, troubleshoot (reagents, calibration, maintenance), rerun QC, document, escalate. Patients before throughput.
What's the difference between internal QC and EQA, and what happens when your lab's EQA performance slips?
IQC monitors daily precision; EQA (e.g. UK NEQAS) benchmarks accuracy externally. Poor EQA triggers investigation, corrective action and UKAS scrutiny — show you know the loop.
You get a critically abnormal result on an urgent sample. What do you do?
Verify (repeat, check sample integrity and history), then phone the requesting clinician per the critical-limits procedure and record the communication. Speed with verification.
What do the HCPC standards of proficiency mean for how you work day to day — and how do you keep your CPD audit-ready?
Practise within scope, maintain competence, safeguard service users — grounded in one example. CPD: a live portfolio (IBMS scheme counts), not a pre-audit scramble.
Tell us about a discrepant or unexpected result you investigated. What was going on?
Show the detective work: pre-analytical causes first (haemolysis, wrong tube, drip arm), then analytical. Finding the cause protects the next patient.
A ward is chasing a result angrily while you're managing an analyser problem. How do you handle the conversation?
Honest timeline, offer alternatives (send-away, repeat sample), stay professional — the lab is a clinical service and the patient is behind the phone call.
Which of the six NHS values feels most relevant in a lab where you rarely see patients — and how do you live it?
'Commitment to quality of care' is a natural fit: every tube is a person. One habit that proves it — checking IDs, chasing odd results — makes it real.
Why biomedical science, and which discipline — haematology, biochemistry, microbiology, histopathology — draws you and why?
Diagnosis behind the scenes is the honest appeal; naming a discipline with a reason (and knowing the department's) shows you've done the homework.
Total laboratory automation and AI-assisted digital pathology are spreading. How does that change the BMS role?2026
Automation moves you up the value chain — validation, interpretation, exceptions, quality oversight. Enthusiasm for running the system, not fear of it.
What does good documentation look like in a lab or trial — and why does it matter so much?
ALCOA in your own words: attributable, legible, contemporaneous, original, accurate. Then the habit — recording in real time, never backfilling.
Tell us about a time your results didn't match what you expected. What did you do?
The scientific reflex: check the method and instrument before doubting the sample, repeat with controls, report honestly. Unexpected results aren't failures.
What do you do if an SOP seems wrong, outdated or impossible to follow as written?
Never silently deviate: flag it through the change/deviation process, follow the current version meanwhile unless it's unsafe. Compliance plus initiative.
