The guideline committee has updated the guidelines for urine, oral fluid and hair 2022.
These guidelines have been communicated within the members of EWDTS and accepted by the board.
The former versions of EWDTS guidelines have been approved by the Laboratory Committee of EA (European co-operation for Accreditation) as a technical document (category 4) and they can be accessed on their website. The approval for these new guidelines will be sought during this year.
