Measurement of Serum Ferritin With a Cryo Detector Mass Spectrometer (CDMS)

"The following samples will be drawn from each study participant immediately after the venipuncture performed for the whole blood donation:~* 1 sample with no anticoagulant (5 ml) for SF measurement with the CDMS method~* 1 EDTA (Ethylendiamintetraazetat) sample (7,5 ml) for a complete blood count with red blood cell indices and reticulocytes~* 1 EDTA sample (2,7 ml) for the measurement of hepcidin~* 1 Li-Heparin-Gel sample (4.7 ml) for the measurement of SF with the ECLIA (Electrochemiluminescence-enzymeimmunoassay) and of the complete set of iron biomarkers (Transferrin Saturation, serum iron, Soluble Transferrin Receptor)~* 1 Li-Heparin-Gel sample (4.7 ml) for the measurement of CRP (C-reactive Protein)~* 1 sample with no anticoagulant (5 ml) for the measurement of SF with the CMIA (Chemiluminescence Immunoassay)~* 1 sample with no anticoagulant (5 ml) for storage"
