Detailed Description

Brief description: The purpose of this study is to assess the iron status and to confirm the usability of the non-invasive ZnPP measurement for screening the different stages of iron deficiency defined by standard measurements from blood.

Detailed Description:

The primary objective of this study is to assess the iron status and the prevalence of the different stages of iron deficiency measured and defined by the standard blood iron measurements and by the non-invasive measurement of red blood cell Zinc Protoporphyrin fluorescence in the microcirculation of the lower lip.

The secondary objective is to compare and to assess the usability of the non-invasive ZnPP measurement versus other standard iron status measurements from blood in distinguishing the different stages of iron deficiency.

Subjects will be enrolled into the study after signing an assent form in addition to having parental informed consent signed. Total study duration is 1 day.
