Laboratory control chart review process flowchart
An editable laboratory control chart review workflow for collecting current data, checking chart completeness, assessing shifts or trends, investigating signals and assigning follow-up actions.
What the laboratory control chart review process is
A useful control chart review starts with a complete, current data set and the related run records. The chart separates that verification from technical interpretation, which prevents an apparent trend from being acted on before the underlying entries are understood.
When a signal or adverse trend appears, the process routes it to investigation of the pattern and affected runs. A second decision distinguishes a documented no-action rationale from corrective follow-up with a named owner.
Adapt the chart rules, review frequency, signal definitions and evidence sources to the method and quality system used at your site. It does not prescribe universal limits or a universal response.
What this flowchart covers
In this template
- Analysts gather the chart data and related run records before supervisory review.
- A completeness decision sends missing or incorrect entries through a correction path.
- The review separates a signal or adverse trend from a record that needs no action.
- Quality assigns and records corrective follow-up when the pattern requires a response.
When to use this template
- You review control, monitoring or performance charts and need the technical interpretation and quality follow-up in one workflow.
- A laboratory has repeated trend discussions but no consistent route from a chart signal to an owner and documented rationale.
- You want an editable process for routine review without embedding method-specific rules into every chart.
How it works
Define chart ownership
Name who extracts or verifies data, who interprets patterns and who can approve a review record or assign follow-up.
Link local signal rules
Connect the signal decision to the approved charting rule, method procedure or monitoring plan rather than placing acceptance limits in this reusable template.
Make follow-up visible
Specify the investigation, CAPA or local action process that receives a significant pattern, then test a recent trend through the route.
Frequently asked questions
What does a laboratory control chart review process cover?
It covers collecting and checking the chart data, assessing patterns, deciding whether a signal needs investigation, assigning corrective follow-up where appropriate and approving a retained review record.
Why verify the data set before reviewing a trend?
A missing, duplicated or incorrectly entered point can change what the chart appears to show. Separating data verification from interpretation gives the team a controlled way to correct the record before deciding on the pattern.
Does every chart signal require the same action?
No. The action should follow the method, context, available evidence and local decision rules. The template makes the decision and owner visible without asserting one response or threshold for every laboratory.
