Type A


We see it as part of the duty of an EQA scheme to give advice to participating laboratories about assay problems related to the EQA when this is asked for.  The EQA response to poor laboratory performance is separately described. We have contacts with developing cardiac Troponin EQA schemes in EU countries and elsewhere. We think it important to foster and contribute to these information links as there aresubstantial inter-assay calibration problems which still remain to be solved.
