This test calculates the percentage of transferrin that is saturated with iron.

Diagnostic Value: Low saturation points to iron deficiency; high saturation may indicate overload or hemochromatosis.

Clinical Significance: Evaluating saturation alongside ferritin and TIBC provides a comprehensive view of iron metabolism.

Symptom Correlation: Altered iron saturation may present with weakness, pallor, or liver-related symptoms.

The Iron Saturation test completes the assessment of iron transport and utilization.
