ERNDIMQA - Control Materials
Control Materials
ERNDIM offers control materials that can be used for internal quality control. The range of analytes is approximately the same as for the corresponding ERNDIM schemes. A kit control material consists of 6 vials with low and 6 vials with high concentrations (except the Homocysteine, this set consist of 6 vials with a low, medium or high level). The range might be expanded in future, guided by requests of ERNDIM participants. For batch specific information please click on the lines below:
Reports for Amino Acids, Purines & Pyrimidines, Organic Acids, Special Assays in Serum/Urine, Acylcarnitines and Pterins in Urine.
ERNDIM offers users of control materials a data management system (Note: this is an option to serve users; users do not have the obligation to use it). The strength of this system is that it does not only monitor the data of the laboratory but also compares the labs results with results of labs using the same batch of internal control materials.
In essence users can submit results every time they do an analytical run with the control material and then download two reports.
· The Review Day Report shows the results of the last run in comparison to
a) the acceptance limits set by the lab,
b) the mean of all previous runs of the lab
c) the mean of all laboratories. Calculation has changed startting from 15th May 2024, see letter May 2024 below
By clicking on the name of a specific analyte in the report, Shewhart charts of that analyte are shown.
· The Cumulative Table report shows the cumulative data of the lab.
