The level of participation should be made dependent on the extent to which other measures have been taken. Other types of measures for ensuring validity of results include, but are not limited to those listed in ISO\/IEC 17025:2017, clause 7.7.1 and ISO 15189:2022 clause 7.3.7.3:<\/p>\n<p class=\"p1\"><b>The level of risk <\/b>presented by the accredited CAB, the sector in which it operates or the methodology it is using.
