Quality Control

Quality system:

  • Management to establish, implement and maintain quality system
    • It should cover policies, systems, programmes, procedures and instructions
  • Communicated, available, understood and implemented
  • Documented in a quality manual
    • available to the laboratory personnel
    • maintained and updated by a responsible person

Part One. 2.1

quality control9
Quality Control

The quality manual should contain at least:

  • Organizational chart; operational and functional activities
  • General and specific quality assurance procedures
  • Proficiency testing schemes
  • Use of reference materials
  • Feedback and corrective action (for testing discrepancies)

Part One. 2.1

quality control10
Quality Control

The quality manual should contain at least (continued):

  • Procedure for dealing with complaints
  • A flow chart for samples – QA is responsible for reviewing and approving sampling procedures. Sampling may be conducted by other persons provided they have been appropriately trained
  • Details of audit and quality system review
  • Qualification of personnel
  • Training and maintaining competence of staff
  • A quality policy statement

Part One. 2.1

quality control11
Quality Control

Control of documents

  • Documentation is essential
  • Procedures to control and review all documents
  • The laboratory must establish and maintain procedures for identification, collection, indexing, access, storage, maintenance and disposal of quality documentation and technical records

Part One. 3.1

quality control12
Quality Control

Records

  • All original observations, calculations and derived data, calibration, validation and verification records, etc. and final results must be retained on record for an appropriate period of time, e.g.
    • whole length of time the drug is on the market
  • Records to contain sufficient information to permit repetition of tests and include, e.g.:
    • identity of the personnel involved in sampling, preparation and testing of the samples
    • Instruments, equipment, etc.

Part One. 4.1 – 4.2

quality control13
Quality Control

Records must be:

  • Legible and readily retrievable
  • Stored and retained in a manner that prevents modification, damage or deterioration and/or loss
  • Held secure and in confidence
  • Includes reports from internal audits and management reviews and records from possible corrective and preventive actions

Part One. 4.3

use of notebooks
Use of Notebooks
  • Bound and pre-numbered
  • Loose sheets – pre-numbered, printing controlled and should be stored as control records
  • Electronic data collection system

Raw data should be recorded at the time of production

quality control15
Quality Control

SOPs: written and authorized

For administrative and technical operations, such as:

  • Purchase and receipt of consignment of materials
    • e.g. samples, reference material, reagents
  • Internal labelling, quarantine and storage of materials
  • Appropriate installation of each instrument and equipment
  • Sampling and inspection
  • Testing materials, describing the methods and equipment used

Part One. 4.4

testing methods and results
Testing Methods and Results
  • Analytical methods and test procedures should be cross referenced (e.g. pharmacopoeia) or detailed to be understood by the local analyst.
  • Formulae – with explanations and simplifications. This makes easy review by a second person
out of specification results
Out of Specification Results

Must be handled based on a written procedure, that includes:

  • Checklist of potential defects (e.g. calculations, methods, visual appearance, test procedure modified, experience of analyst during test, calibration of equipment …)
  • Similar checklist for potential deviations in production
  • Checking sampling and sampling devices
  • Guidance on when re-sampling and re-testing may be required and documented justification in each instance
  • Inclusion of known control sample in any testing
approval and rejection of results
Approval and Rejection of Results
  • Before approval or rejection – criteria to be used and results to be averaged should be specified in SOP(s)
  • Criteria to include - averaging and/or rounding results and comparing results against specifications
  • Control charts can be used to detect trends and atypical results (see www.ivthome.com)
  • Rounding results should be according to pharmacopoeial requirements (see also ICH Q3A)

NB: take care when averaging results from atypical values e.g. outliers, or single result out of specification limits

quality control19
Quality Control

Other SOPs:

  • Qualification, analytical apparatus
  • Calibration, maintenance, cleaning, sanitation
  • Safety measures
  • Personnel matters including
    • qualification, training, clothing, and hygiene
  • Environmental monitoring
  • Preparation and control of reference materials

Part One. 4.4

  • For computer software developed by the user:
    • this documented in detail
    • validated or verified as being adequate for use

Part One. 5.1

use of primary and secondary standards
Use of Primary and Secondary Standards
  • SOP required on – use, records, acquisition, identification and storage
  • For Pharmacopoeial methods – reference standards should be acquired from that pharmacopoeia.
  • Secondary standards to be routinely tested against the primary standard
  • When a non-Pharmacopoeial standard is used as a reference for assay the mean and standard deviation of the assigned assay value should be known. Retest/expiration date should be assigned
