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 Intervention
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)

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single
Primary Purpose: Diagnostic
Official Title: Swiss Functional Iron Deficiency Study
