A laboratory must possess written SOPs used by laboratory personnel for the analysis of samples. A laboratory must prepare written procedures for all laboratory activities including, but not limited to, sample acceptance, sample analysis, operation of instrumentation, generation of data and performance of corrective action. Only the laboratory technical director or quality assurance officer may approve changes in SOPs. Such changes may be effective only when documented in writing.
Actual practice must conform to the written procedures. The laboratory must maintain copies of the methods from which the procedures are developed. A laboratory must ensure that the applicable requirements are incorporated into each procedure. All quality control measures must be assessed and evaluated on an ongoing basis. QC acceptance criteria in the laboratory's QA manual must be used to determine the validity of the data.
A copy of each written procedure must be available to all personnel that engage in that particular activity.
An analyst must use the laboratory's SOP beginning on the effective date for all laboratory activities for the analysis of samples for which accreditation is required.
A laboratory must maintain a record of effective dates for all procedures. A copy of the procedure and the record of effective dates must be maintained for the same period of time that records of the data generated by those procedures are required to be maintained.
A laboratory must submit an electronic copy of its laboratory SOPs to the accreditation officer at the time of application.
All changes to the SOPs must be documented. Changes to the SOPs must be incorporated at least annually. All updated SOPs must include the signature of the managing agent upon revision.
