Summary

ZnPP is being build in the case of a functional iron deficiency. Zinc instead of iron is implemented into protoporphyrin IX. This ZincProtoporphyrin (ZnPP) can be detected non invasively. Non invasive and invasive optical measurement of ZnPP will be compared. Additionally ZnPP measurements will be compared to other iron deficiency parameters for validation by the investigators.

Detailed description

Zinc-protoporphyrin (ZnPP) will be measured by a fluorescence technique. Restricted wave light (407/425 nm) is used to detect ZnPP in the bloodstream non-invasively through the oral mucosa. The spectroscopic measurements are translated into a ZnPP value (mumol/mol heme). The non-invasive measurement of ZnPP is validated and compared to optical measurement of ZnPP in whole blood and high performance liquid chromatography (HPLC) measurement of ZnPP in whole blood. The ZnPP value is compared to other iron-deficiency parameters: Ferritin, Transferrin saturation and soluble Transferrin receptor.
