Work through a QC failure, step by step

Every tech investigates the same way, in the same order, and it ends in a signed record you can put in front of an inspector. Your draft saves in this browser only. Don't enter patient identifiers.

What happened?

Record the QC event exactly as you saw it.

Analyte / test

Instrument

Date

Time

Control material & lot

Reagent lot / pack

Last calibration (date)

Performed by (initials)

Control results

Which rule, which pattern?

The rule that fired tells you whether to think random or systematic first.

Rule violated

Which levels are affected?

Direction

Before you touch anything

Protect patients first. Then investigate.

Don't rerun controls until they pass.A single repeat with fresh control may be reasonable when random error is suspected and your procedure allows it. Repeating again and again hides the problem and isn't an investigation.

Structured investigation

Ordered for the pattern you picked. Tick what you checked and write what you found, including "no issue found".

Root cause and corrective action

Most likely root cause

Corrective action taken

Repeat QC after correction

Patient testing resumed at

Patient look-back

Patients run since the last acceptable QC may be affected.

Last acceptable QC (date/time)

Patient samples in that window

Samples rerun

Outcome

Who was notified (clinicians, supervisor, director)

Follow-up / prevention

Your investigation record

Check it, print it or save it as PDF, then pass it to your supervisor for review.

LabReady Pro is a training and documentation-support tool. It doesn't replace your laboratory's procedures, the manufacturer's instructions, or the judgement of your supervisor and laboratory director, and it makes no patient-care decisions.
