QMEQAS: Quebec Multielement External Quality Assessment Scheme

This scheme was initiated in 1996 to supply laboratories having multielement capabilities, such as ICP-MS (Inductively Coupled Plasma – Mass Spectrometry), with a wide range of analytes in human biological matrices that are not freeze-dried. Approximately 100 laboratories are involved in this program.

Participants receive three rounds per year, each containing nine PTMs. The biological matrices provided are hair, blood, serum and urine. The list of analytes available by matrix can be found here.

This scheme is ISO/IEC 17043 accredited.
