Abstract
CONTEXT: In epidemiological research, it is very important to test the stability of biomarkers as function of both storage time and temperature. OBJECTIVE: In this study, the stability of biomarkers of the iron status was tested up to 1 year of storage. MATERIALS AND METHODS: The biomarkers include total iron, unsaturated iron binding capacity, ferritin, transferrin, soluble transferrin receptor, ceruloplasmin and haptoglobin. RESULTS: The concentrations of all biomarkers tested remain constant upon storage at -20, -70 and -196 °C. CONCLUSION: All biomarkers of the iron status were stable at the temperatures tested for 1 year.
