Actual (reported)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.

Actual (reported)Validation of the non-invasive ZincProtoporphyrinIX measurement
The value is compared to optical measurement of ZincProtoporphyrin in whole blood; in addition the value is compared to HPLC measurement in whole blood
Baseline
Comparison of the ZincProtoporyphyrinIX value to other iron-deficiency parameters
Baseline
Patients present themselves before an operation to the Anesthesiologist. They are screened for study eligibility.
Within 30 seconds, a measurement is performed on the lip of a patient to determine a ZincProtoporphyrin value
