Recognizing a Deviation Early
Part of Clinical Laboratory (LAB) Training: Recognizing and Escalating Deviations.
About 2 minutes. Free, in your language, no account needed.
A deviation is any departure from the protocol or manual
It is not a measure of how careful you are. It is a factual statement that what happened differed from what was specified.
Treating the word as an accusation is what makes people slow to report, and slow reporting is what turns small problems into large ones.
The ones that are easy to miss
A sample processed six minutes past its window. An aliquot short. A spin at the right rpm but the wrong g. A label handwritten because the printer failed.
Each looks minor at the bench. Each is a departure, and each should be recorded.
"Probably fine" is a signal, not a conclusion
When you catch yourself thinking a sample is probably fine, that is the moment to write it down.
Probably fine means you noticed something. Your noticing is the information. Whether it is acceptable is somebody else's call, made with stability data you do not have.
Why the bench should not decide impact
Deciding a deviation is immaterial requires knowing the endpoint, the assay, the analyte stability and the statistical plan.
The sponsor holds all four. You hold the observation. The division of labor is deliberate.
Report facts, separated from interpretation
"Plasma separated at 14:42, collection 13:35, manual specifies within sixty minutes." That is a fact.
"Slightly late but the sample looked normal" mixes an observation with a judgment, and the judgment is the part you are not positioned to make.
Same day, every time
The value of a deviation report decays fast. Same day means the cause is still reconstructible and a corrective action can still prevent the next one.
Deviations are expected
Studies plan for them. A site reporting zero deviations is not believed, and rightly.
What sponsors look for is whether deviations are found, reported and corrected. That is evidence the system works.
