Diagnosis of late presenting subarachnoid hemorrhage: Comparison of methods for cerebrospinal fluid ferritin

Abstract

The precision of the Dimension Vista measurements was considerably better than that of the BN ProSpec. The Dimension Vista results correlated well with those of the comparative method, yielding slightly lower values. This is reflected in the reference intervals. These findings permit the use of the routinely available Ferritin assay of the Dimension Vista for measuring Csf-Ferritin and complementing the late diagnosis of SAH outside office hours of specialized Csf laboratories.
