SKML dispatches EQA samples to scheme participants and provides a website for on-line submission of results and access to scheme reports by participants.
Existing quantitative scheme participants can log on to the results submission website here.
- Acylcarnitines in dried blood spots (3 centres)

Qualitative schemes are planned and managed by members of the ERNDIM Scientific Advisory Board and organised in partnership with CSCQ, a Quality Assurance provider based in Switzerland.
CSCQ dispatches the Acylcarnitines in DBS, DPT and Qualitative Organic Acids EQA samples to the scheme participants. CDG and Urine MPS samples are dispatched by SKML. CSCQ also provides a website for on-line submission of results and access to scheme reports for the Acylcarnitines in DBS, CDG, DPT and Qualitative Organic Acids and Urine MPS samples.
Existing qualitative scheme participants can log on to the CSCQ results submission website here.
Pilot schemes are planned, managed and organised by individuals with expertise in the relevant area. The schemes are monitored by the ERNDIM Scientific Advisory Board for a minimum period of 2 years. If after this time the Scientific Advisory Board is satisfied that the scheme is successful it will recommend that the Executive Committee adopts the scheme as an official ERNDIM EQA Scheme.
In 2021 we will be running 1 pilot scheme:
- Cognitive Amino Acids
Participation in pilot schemes is limited but if you would like to be contacted if it is possible for us to widen participation in these schemes please contact us.
We would also like to hear about suggestions for new schemes that we might consider in the future. If you would like to comment please contact us.
