Background and clinical significance

In vitro test for the quantitative determination of soluble transferrin receptor (sTfR) in human serum and plasma.

Soluble transferrin receptor measurements, performed with this assay, in human serum and plasma are used as an aid in diagnosis and monitoring of iron deficiency. Causes for iron deficiency can be broadly classified as: insufficient iron uptake, inadequate iron mobilization, excess iron loss, increased iron demand.
