Technical explanation
What it means
Uncertainty is important because a measured value alone may not fully explain confidence in the result or how close it is to an acceptance limit.
Why it matters
- Supports technically sound pass/fail review.
- Helps users compare measurement confidence across certificates.
- Connects calibration results with decision rules.
- Is important in accredited calibration reporting.
How hospitals and biomedical teams use it
- Review uncertainty along with measured value and tolerance.
- Use an agreed decision rule where pass/fail conclusions are required.
- Do not ignore uncertainty near acceptance limits.
- Ask the laboratory to clarify uncertainty reporting when needed.

Frequently asked questions
Is lower uncertainty always better?
Lower uncertainty can support better confidence, but the required uncertainty depends on equipment tolerance and intended use.
Does every hospital user need to calculate uncertainty?
Usually no. Users should understand its meaning and review it with acceptance criteria where relevant.
