Since 1982 we have been carrying out an external quality assessment
scheme and certification for occupational-medical and
environmental-medical toxicological analyses in biological
materials. Scheme, evaluation and certification are based on the
guidelines of the German Federal Medical Council (Bundesärztekammer).
This scheme comprises the determination of toxicological parameters
in blood, plasma/serum and urine samples of the occupational as well
as the environmental concentration range. About 200 laboratories
from more than 22 countries regularly participate in this scheme.
