We already have had our Cholinesterase Specimen Exchange Scheme running for some time, but we are now opening this up for a much wider range of analytes across a range of matrices.

This is a true community collective product. You have to contribute your own Specimens to become part of the service but all the data is presented in our familiar house-style with occasional added commentaries for that extra value added component.

Please use the sign up form to register your interest in this scheme (quoting your UK NEQAS Laboratory ID where available). We would encourage you to provide us with details of which analytes you measure and the analyser and ‘kit’ (reagent and calibrator) you are using. This will help us tailor the scheme to your needs.
