  • Taking samples of cerebrospinal fluid may also reveal siderosis through xanthochromia, elevated presence of red blood cells, high iron and ferritin concentrations, and elevated levels of the proteins Tau, beta amyloid (Aβ42), neurofilament light protein (NFL), and glial fibrillary acidic protein (GFAP), but the CSF is sometimes normal.

  • blood
  • Gradient-echo T2-weighted images have a higher sensitivity for hemosiderin deposition ( Fig 2 A , - B ). The magnetic susceptibility effects of blood-degradation products such as ferritin and hemosiderin are also more pronounced at higher field strengths. (ajnr.org)
  • Results of laboratory studies to monitor liver enzymes, complete blood counts, and ferritin that were drawn over the course of this period were stable. (ajnr.org)
