in addition to the recommendation itself***, its grading has to be equally born in mind, ie:
-Quality of evidence assessed by GRADE: moderate
-Strength of recommendation based on GRADE criteria: conditional

***Recommendation
HbA1c can be used as a diagnostic test for diabetes providing that
stringent quality assurance tests are in place and assays are
standardised to criteria aligned to the international reference values,
and there are no conditions present which preclude its accurate
measurement.
An HbA1c of 6.5% is recommended as the cut point for diagnosing
diabetes. A value of less than 6.5% does not exclude diabetes
diagnosed using glucose tests.
this means that the implementation of this recommendation is "conditional" (depends on local, organizational, financial conditions, patients preferences, etc)
