STANDARD OPERATING PROCEDURE (SOP)

Analyst Qualification in Quality Control Laboratories

SOP No. QC/SOP/___ Effective Date ___
Revision No. 00 Department Quality Control

1. Purpose

To define a comprehensive and step-by-step procedure for qualification, authorization, and requalification of analysts working in the Quality Control laboratory, ensuring accuracy, reproducibility, data integrity, and compliance with GMP, WHO, FDA, EU-GMP, and ICH Q2 requirements.

2. Scope

This SOP applies to all analysts performing chemical and instrumental analysis in the Quality Control laboratory, including new employees, experienced analysts, reassigned staff, and contract personnel.

3. Responsibilities

  • QC Head: Final approval of analyst qualification and authorization.
  • QC Manager / Supervisor: Planning, execution, assessment, and recommendation.
  • Analyst: Compliance with SOPs, training, and qualification activities.
  • Quality Assurance: Oversight, compliance verification, and inspection support.

4. Detailed Step-by-Step Procedure

4.1 Initiation of Qualification

Upon joining or reassignment, the QC Manager shall initiate analyst qualification. Educational background, experience, and job responsibilities shall be reviewed. A documented qualification plan identifying required tests and instruments shall be prepared.

4.2 Induction and GMP Training

The analyst shall complete induction training covering laboratory safety, GMP/GLP, data integrity, ALCOA+ principles, and Good Documentation Practices. No analyst shall enter the laboratory without documented completion of this training.

4.3 SOP and Method Training

The analyst shall be trained on all relevant SOPs and analytical methods. Training shall include method principle, critical parameters, acceptance criteria, calculations, and documentation requirements. Training effectiveness shall be documented.

4.4 Instrument Training

Hands-on instrument training shall be provided, including system setup, parameter selection, system suitability testing, data acquisition, and shutdown. The analyst shall not operate any instrument independently prior to qualification.

4.5 Qualification – Observation Stage

The analyst shall observe a qualified analyst performing the complete test as per the approved method, including sample preparation, analysis, calculations, and documentation.

4.6 Qualification – Supervised Performance Stage

The analyst shall perform the test under direct supervision and complete a minimum of three (03) consecutive analyses.

4.7 Qualification – Independent Performance Stage

After successful supervised analysis, the analyst shall perform at least one complete analysis independently. All data shall be reviewed and approved by the QC Supervisor.

5. Acceptance Criteria for Analyst Qualification

5.1 System Suitability Criteria

  • %RSD of standard injections: ≤ 2.0%
  • Theoretical plates: ≥ method requirement
  • Tailing factor: ≤ 2.0
  • Resolution (where applicable): ≥ 2.0

5.2 Assay / Quantitative Test Criteria (Example)

  • Individual assay results: 98.0% – 102.0% of label claim
  • Difference between analyst result and reference result: ≤ 2.0%
  • %RSD of replicate sample preparations: ≤ 2.0%

5.3 Precision / Repeatability Criteria

  • Minimum three replicate sample preparations
  • %RSD of results: ≤ 2.0%

5.4 Documentation and Data Integrity Criteria

  • No missing raw data
  • No unapproved overwriting or backdating
  • All entries signed and dated contemporaneously
  • Calculations verified and traceable

5.5 Qualification Decision Criteria

  • Qualified: All numerical and procedural criteria met
  • Not Qualified: Any failure → retraining and repeat qualification

6. Authorization of Analyst

Upon successful qualification, the QC Supervisor shall recommend authorization. The QC Head shall review all records and approve authorization. Authorized tests and instruments shall be recorded in the Authorized Analyst List.

7. Requalification

Requalification shall be performed annually or when triggered by method revision, instrument change, prolonged absence (> 6 months), analyst-related OOS/OOT, or regulatory observations.

8. Disqualification and Retraining

An analyst shall be disqualified in case of repeated errors, procedural non-compliance, or data integrity concerns. Retraining and reassessment shall be mandatory before reauthorization.

9. Documentation and Records

All training, qualification, authorization, and requalification records shall be maintained as per GDP and site document retention policy and shall be readily available for inspection.
