Brief Summary:
The purpose of the study is to define laboratory parameters which are best suited to diagnose functional iron deficiency. Functional iron deficiency is a condition where - due to the lack of iron bioavailability - the patient suffers from symptoms such as fatigue and weakness, or his/her capacity to produce red blood cells is reduced.

Condition or disease Intervention/treatment Phase
Functional Iron Deficiency Procedure: %-hypo (laboratory parameter, functional iron deficiency) Procedure: CHr (laboratory parameter, functional iron deficiency) Procedure: RET-HE (laboratory parameter, functional iron deficiency) Not Applicable
