Oxidative stress

Background and utility

Lipid peroxidation, as a marker for oxidative stress,  is known to be influenced by various pathological conditions, including iron overload and/or the presence of circulating toxic iron species NTBI and LPI. Malonaldehyde (MDA), one of the end products of lipid peroxidation, is the most commonly used marker for this process.



As a measure of lipid peroxidation, MDA concentrations are measured in 150 µl plasma or serum in duplicate.1,2  The lower limit of detection of the method is 0.12 µM. The (reference) range of serum  MDA as  measured in an adult Dutch population is 0.16-0.64 µM.

Responsible laboratory

Oxidative stress measurements are coordinated and performed by the Hepcidinanalysis.com initiative that is embedded in the Translational Metabolic Laboratory of the Department of Laboratory Medicine of the Radboudumc, Nijmegen, the Netherlands.
