2. On-site Assessment & Post-Assessment Actions

The accreditation process typically involves several stages, including on-site assessment and post-assessment actions. Here is an overview of these stages:

1. Application and Document Review:

   • Laboratories begin the accreditation process by submitting an application to the accreditation body.
   • The accreditation body reviews the laboratory’s documentation, including quality manuals, procedures, and other relevant documents.

2. Pre-assessment (Optional):

   • Some accreditation bodies conduct a pre-assessment to help the laboratory identify areas that may need improvement before the formal assessment.
   • The pre-assessment is not mandatory but can be beneficial for the laboratory.

3. On-site Assessment:

   • A team of assessors appointed by the accreditation body conducts an on-site assessment.
   • The assessors evaluate the laboratory’s facilities, personnel competence, equipment, procedures, and documentation against the clinical pathology accreditation standards.
   • They may observe the laboratory staff performing actual tests or calibrations.

4. Assessment Report:

   • The assessors compile a detailed assessment report that highlights areas of compliance and non-compliance with the importance of laboratory accreditation standards.
   • The report includes recommendations and corrective actions for any identified non-compliance.

5. Decision by Accreditation Body:

   • Based on the assessment report, the accreditation body makes a decision on whether to grant accreditation to the laboratory.
   • If granted, the laboratory receives an accreditation certificate.

6. Post-Assessment Actions:

   • Corrective Actions: If non-compliance is identified, the laboratory must implement corrective actions to address the deficiencies.
   • Follow-up Assessments: The accreditation body may conduct follow-up assessments to verify that corrective actions have been implemented.
   • Continuous Improvement: Accredited laboratories are expected to continually monitor and improve their processes to maintain compliance with clinical pathology accreditation standards.
   • Surveillance Audits: Periodic surveillance audits may be conducted to ensure ongoing compliance.

7. Accreditation Maintenance:

   • Accreditation is typically granted for a specific period, after which the laboratory must undergo a renewal process.
   • Renewal involves submitting updated documentation and may include a re-assessment to ensure continued compliance.

8. Appeals Process:

   • Laboratories have the right to appeal if accreditation is denied or revoked. The appeals process allows for a review of the decision.

Effective communication between the accreditation body and the laboratory is essential throughout the process to address any questions or concerns and facilitate a smooth accreditation journey. Accreditation is a dynamic process, and laboratories are encouraged to actively engage in continuous improvement to enhance their capabilities and maintain accreditation status.
