WHO Guidelines For Analytical Method Validation

Analytical Method Validation

Toward the finish of 2015, the WHO adjusted its Appendix 7 to the most recent innovative guidelines. Appendix 7 offers help to non-sterile procedure validation. Presently, further changes to WHO rules are in sight. One of these progressions concerns the rule on procedure validation which is right now accessible as a draft and can be remarked on until July, twelfth 2016. It would be ideal if you find here an investigation of this draft.

The draft contains 21 pages partitioned into 13 sections and one section with references.

Appendix 1 Validation of HVAC frameworks (at present officially accessible as an updated draft)

Appendix 2 Validation of water frameworks for pharmaceutical use.

Appendix 3 Cleaning Validation

Appendix 4 Analytical Balances method validation

Appendix 5 Validation of automated frameworks

Appendix 6 Qualification of frameworks and hardware

The introduction depicts validation as a basic piece of GMP and GCP. Validation likewise incorporates capability and a lifecycle including a “progressing audit” for consistent upgrades. The need, degree, and profundity of validation exercises ought to be found on quality hazard the board standards.

  • The accompanying assets are recorded:
  • Time
  • Accounts
  • Workforce (multidisciplinary group). Up until this point, an outline of the introduction.

Section 4 tends to the connection between validation and capability. “Capability and validation are basically the equivalents” whereby capability is ordinarily utilized in connection to gear and utilities, and validation in connection to frameworks and procedures.

Part 10 Qualification

Comprised of practically 3.5 pages, Chapter 10 (Qualification) is moderately broad. It proposes that there are diverse ways to deal with capability. The V-Model for Direct Impact Systems is given for instance. However, the model presents contractions which are not clarified (for example UAT).

“Ordinarily” – citing the content – „qualification ought to be finished before procedure validation is performed”. “Typically”, capability should start with client prerequisite particulars (URS). Part 11 and 12

The substance of Chapter 11 (Change Management – just 3 passages) and Chapter 12 (Deviation Management, only one section) are moderately low contrasted with Chapter 13 on alignment and check which is significantly progressively broad (one page). Here, the content features the need for customary alignment with detectable adjusted estimating gadgets.

IQ is considered as suitable capability organize for alignment and check of hardware. Regardless of whether gadgets or instruments ought to be adjusted ought to be founded on an effect or hazard appraisal.


In spite of the fact that this rule has been thought as a superordinate rule for other validation and capability rules, it has – in its present draft status – generally little connection to the validation lifecycle approach as required in Annex 15 and FDA’s procedure validation rule. There are no references to advancement which speaks to the reason for a cutting edge validation approach.

All things considered, occasional revalidation is essentially required. Curiously, references to the utilization of factual methods – where fitting – repeat over and over. Another fascinating angle is the notice of “GEP” and “Appointing” in the glossary whereby no further clarification is given with respect to the V-Model.

Over the span of capability tests, contingent endorsements (as referenced in Annex 15) are not planned. The determination as indicated by which a “like for like” substitution requires requalification is intriguing.

This is a complexity to PIC/S’s archive “PI 006-3, Recommendations on Validation Master Plan, Installation and Operational Quali.
