Organization and Management of a Pharma QC Laboratory

In short: A pharmaceutical quality control (QC) laboratory must be legally accountable for its results, free from commercial and other pressures, and organised so that every person’s role, authority and deputy are clear. WHO’s good practices for QC laboratories (TRS 1052, Annex 4, 2024, section 3.1) set this out; EU GMP Chapter 2 and ICH Q10 add the manufacturer’s view. This article is for QC analysts, supervisors and pharmacy students.

Why organisation matters in a QC laboratory

A test result is only trusted when it is clear who produced it, who checked it and who was allowed to decide on it. The way a laboratory is structured, and the way management supports it, is the base on which methods, equipment and records stand. In a manufacturing company the QC laboratory is part of the quality system of the whole site.

Requirements for the laboratory and its management

WHO TRS 1052 Annex 4 (2024), section 3.1, treats the following as the basics of structure and management.

Legal status and senior management

The laboratory, or the organisation it belongs to, should be legally authorised to operate and be held responsible for its test results, certificates of analysis and other work (para 3.1). Senior management is responsible for setting up and controlling an effective quality system and a data governance system, and for making sure policies, training and technical systems are in place (para 3.2).

Authority, resources and impartiality

According to para 3.3, the laboratory should:

have managerial and technical staff with the authority and the financial, human and infrastructure resources to carry out their duties;
protect management and staff from commercial, political, financial and other pressure or conflicts of interest that could affect their work or impartiality;
have a procedure for declaring conflicts of interest, with measures to reduce the risk and a documented, continuing review of the declarations.

Confidentiality

The laboratory should have a policy and procedures to keep confidential all information shared with it or created by it, whether oral, paper or electronic. This includes information in marketing authorisations, analytical methods, and the transfer of results or reports. Contractors and anyone acting for the laboratory should also keep information confidential and work in line with its quality management system.

Structure, roles and deputies

The same paragraph expects the laboratory to:

define its organisation and management structure with organisational charts, including its place in any parent organisation and the links between management, technical work, support services and the quality management system;
specify the responsibility, authority and interrelationships of everyone who manages, performs, verifies, reviews or approves work affecting results, for example in the job description;
allocate responsibilities precisely, including units for particular types of medicines where needed;
nominate trained substitutes or deputies for key management and specialised scientific staff;
supervise staff, including trainees, through senior staff who know the methods, their purpose and how to assess the results;
keep overall responsibility for technical operations and for providing the resources needed with management.

Quality manager

The laboratory should designate a quality manager who, whatever other duties he or she has, makes sure the quality management system is followed. The quality manager should have direct access to the highest level of management.

Communication, traceability and documents

Information should flow between staff at all levels, and staff should understand why their activities matter. The laboratory should be able to trace a sample from receipt through every stage of testing to the analytical test report. It should also keep an up-to-date collection of all specifications and related documents, and have suitable safety procedures.

Sample registry

A registry should receive, distribute and supervise the sending of samples to the right units, and keep records of all incoming samples and the documents that come with them. In a large laboratory, where several units may test the same sample, communication and coordination between those units must also be arranged.

The manufacturer’s view: EU GMP Chapter 2 and ICH Q10

In a licensed manufacturing site, the QC laboratory is covered by EU GMP Part I, Chapter 2 (Personnel):

Topic	What the guideline says (summary)	Reference
Resources	Enough staff with the right qualifications and experience; senior management provides human, financial, material and equipment resources; no individual should carry duties so extensive that quality is at risk	Clause 2.1
Organisation chart	The relationships between the heads of Production, Quality Control and, where applicable, Quality Assurance or the Quality Unit, and the position of the Qualified Person, must be shown	Clause 2.2
Job descriptions and deputies	Responsible people have written duties and adequate authority; duties may be delegated to designated deputies of suitable qualification; no gaps or unexplained overlaps	Clause 2.3
Senior management	Has ultimate responsibility for an effective quality system and for defining and communicating roles; sets a quality policy and takes part in management review	Clause 2.4
Key personnel	Senior management appoints the heads of Production and Quality Control (and a Qualified Person where needed); the heads of Production and Quality Control must be independent of each other	Clause 2.5
Head of Quality Control	Responsible, among other things, for approving or rejecting materials and products, for making sure all necessary testing is carried out and its records evaluated, and for approving and monitoring contract analysts	Clause 2.8

ICH Q10 (Pharmaceutical Quality System, 2008), section 2.1 on management commitment, states that senior management has ultimate responsibility for an effective quality system. Management should take part in it, support it visibly, set up escalation of quality issues, define roles and interrelationships, hold management reviews, promote continual improvement and commit resources.

Example in-house criteria for a small laboratory

The following are examples a site may adopt, not regulatory requirements. They show how the principles above can be turned into practice.

Each analytical role has a written job description and a named deputy who has been trained and signed off for the role (example in-house criterion).
The organisational chart is reviewed and re-issued whenever a role changes (example in-house criterion).
Every analyst and supervisor signs a conflict-of-interest declaration at joining and each year (example in-house criterion).
The sample registry is a controlled logbook or electronic system, with each sample’s receipt, issue to unit and return recorded (example in-house criterion).

Records

Sample registry entries, organisational charts, training and conflict declarations are part of the laboratory’s records. Batch-related quality records should be kept for at least 1 year after the expiry date of the respective product batch (EU GMP Part I Chapter 4 §4.11, which says 5 years after Qualified Person certification if that is longer; 21 CFR 211.180(a)), and longer if local law or the marketing authorisation requires.

Frequently asked questions

Must the quality manager be a separate person?

WHO says a member of staff should be designated as quality manager, whatever other duties he or she has, and should have direct access to the highest level of management. Depending on the size of the laboratory, the quality manager should also stay independent of routine analytical work (TRS 1052 Annex 4, para 5.3).

Why must Production and QC heads be independent?

EU GMP Chapter 2, clause 2.5, requires that the heads of Production and Quality Control are independent of each other so that release decisions are not influenced by production pressure.

Why are deputies required?

So that a key task, such as approving results or reports, can continue safely when the usual person is absent, without informal hand-overs (WHO para 3.3; EU GMP clause 2.3).

Who is responsible for the results the laboratory issues?

The laboratory, or the organisation it is part of, which is held legally responsible for its test results and certificates of analysis (WHO para 3.1).
