Ian, CSF ferritin is massively raised in siderosis. We use a reference range of <12 ug/L derived from CSF obtained from patients in our institution where no pathology had been demonstrated.

We have a request for this in a patient who has an apparently equivocal MRI scan, with a previous history of surgical brain procedures (a predisposing factor). I can find very little about it in an, albeit brief, literature search, though one paper from presented two cases where the CSF ferritin was greatly elevated (values of 90 and 31 respectively, with a reference range of <12ug/L, though no indication from where this was derived). I have tried Sheffield and Leeds in our locale, plus Queen's Sq in London.
