Laboratory internal audit process flowchart

What the laboratory internal audit process is

An internal audit is more credible when independence and resources are considered before fieldwork begins. This template puts that decision after planning, with a route to assign another qualified auditor or revise the plan when the original arrangement is not suitable.

During the review, an auditor can document a conclusion or classify a finding with the area owner. Quality then assesses whether the proposed response has an adequate owner and route, returning it for revision where it does not.

Adapt scope, auditor competence, evidence methods, finding categories and action governance to the program at your site. The chart documents a process, not a certification or compliance result.

What this flowchart covers

In this template

• Quality schedules the audit while an internal auditor prepares the scope and review questions.
• An independence and resourcing decision prevents unsuitable audit arrangements from proceeding unnoticed.
• Records, activities and interviews lead either to a documented conclusion or a classified finding.
• Area owners revise inadequate responses before Quality approves the audit record and follow-up.

When to use this template

• You are building or refreshing an internal audit workflow for a laboratory quality program.
• Auditors and area owners need a clear path from observation to response ownership and retained evidence.
• You want findings and no-finding conclusions to have equally traceable closeout records.

How it works

1. Assign independent reviewers

   Replace the role labels with the qualifications, independence checks and alternate assignment route your audit program requires.

2. Define response review

   Specify what makes a finding response usable, who approves it and where actions that need a different process are handed off.

3. Practice both outcomes

   Run one recent audit with no finding and one with an incomplete response through the chart to verify that neither path loses its record.

Frequently asked questions

What does a laboratory internal audit process flowchart cover?

It covers audit planning, reviewer independence, examination of records and activities, documenting a conclusion or finding, reviewing the response plan, approving the record and tracking follow-up.

Why include an auditor independence decision?

A planned review may need a different auditor or a revised scope when the original arrangement is not sufficiently independent or resourced. Making that choice visible prevents it from being handled informally.

What should happen when a response plan is inadequate?

Return it to the responsible area for revision, clarify ownership and retain the review record. The local program should define how findings are classified, escalated and followed up.
