Preparing for an Audit

Preparing for an audit is a very important step for your laboratory. The external audit from a 3rd party accreditation body is the final step before your laboratory receives accreditation to ISO 17025.

The auditors have several objectives:

  • Verify that your documentation meets all of the requirements of the standard.
  • Ensure your employees know their role in the QMS and are familiar with the ISO 17025 requirements that pertain to their role in the organization.
  • The procedures and processes are correctly followed.

The results will either grant you certification or require corrective actions your organization must meet before becoming accredited.

When the day of the accreditation audit has arrived, it is time to showcase your QMS and how you have addressed the requirements. Being audited is time-consuming and costly so you want to make sure that you are well prepared. Here are some tips from to help your laboratory ensure that you are ready in order to have a successful audit.

Give the laboratory ample time to prepare

Preparing your lab for an audit takes time and effort. When you have decided that receiving accreditation is necessary for the laboratory, you should set goals and give an appropriate amount of time to meet the requirements of the standard.

Prepare the employees

Your employees are the ones that will demonstrate that your laboratory is complying with the requirements of ISO 17025. Before the audit, you will want to make sure that all employees know when the audit will be taking place and what the scope of the audit is. Each employee should have a clear idea of the lab’s competence objectives, and how their role contributes to them. Each employee should have proper training on the tasks that they perform.

When you are preparing your employees to answer questions, remember this is not a test, auditors are not looking for an exact answer, rather they want to know how employees go about finding information and answers. Do procedures provide information? If the information is not in a procedure, where does the employee go next, do they ask a supervisor? suggests Several Employee Training Courses to help prepare your laboratory for the audit:

Documented Information

Documented information is another important aspect of preparing for your audit. When you are preparing for your audit, you need to ensure that documents and record lists have been updated. Additionally, all documents need to have been reviewed, approved, communicated and followed by everyone involved in the process or activity. You should also ensure that no one is using outdated documents.

Processes and Procedures

Processes and Procedures need to be carefully followed. Your laboratory needs to make sure all processes are meeting the planned arrangement you set out to achieve, and that they are being followed and performed in the same and correct way by all employees.

Prepare the facility

When you are preparing for the audit your laboratory needs to be well-organized and cleaned. If your facility is a mess, it is easy to miss nonconformances. You want to make sure that you are well aware of every area of the facility so that you do not have to encounter any hidden issues during the audit. When getting your organized ready for the audit, check bulletin boards, counters, drawers, etc for uncontrolled documents, uncalibrated measuring and monitoring instruments and unidentified parts or supplies.

Internal Audit

The organization must conduct an internal audit. Not only is this a requirement of the ISO standard, but it is also the best way to catch any major nonconformances. Internal audits should be taken seriously. They are also a great way to prepare staff for the interview process.

Management Review

The management review should take place following the internal audit. This step should consist or reviewing past internal audit findings and take corrective actions where necessary.

Review past Internal Audit Findings

After your laboratory undergoes an Internal Audit, these findings should be reviewed in a closing meeting to everyone involved. The meeting should be detailed to give the laboratory an understanding of where they are falling short and how they can improve. This information should be given in an objective and friendly manner and suggestions should be informed constructively.

The laboratory needs to determine who is responsible for monitoring the actions necessary to make corrections. The results of the audit need to be recorded along with any corrective action taken. Documentation is necessary to ensure that nonconformities are taken care of and that improvements are made.

Review Corrective Action Process

Reviewing past audits and taking corrective action to any nonconformances is key to accreditation. We recommend taking corrective actions immediately to avoid compromising your ability to achieve accreditation. A major problem found by the auditor could delay your accreditation and leave you scrambling to establish a process to fix the issue. Performing internal audits in preparation for your third-party auditor is ideal.

Have a professional audit

When the auditor arrives, your goal should be making a good first impression and to act professionally. Auditors are there to help the laboratory uncover any nonconformances and weaknesses in order to take action, improve and become certified. Remember they want your laboratory to succeed as well.
