Iron Studies Explained: Ferritin, Iron, TIBC & Saturation

Iron panels include ferritin (stores), serum iron, TIBC/transferrin, and transferrin saturation (iron ÷ TIBC). Use your lab's ranges.

Patterns

• Iron-deficiency: low ferritin + low saturation; TIBC often high; CBC may show microcytosis.
• Inflammation pattern: ferritin normal/high with low iron and low/normal TIBC; saturation low.
• Overload: very high ferritin with high saturation – consider further testing.

Educational next steps

1. Look for loss (menstrual/GI), low intake, or demand (pregnancy).
2. Diet: iron-rich foods + vitamin C; avoid tea/coffee with iron-rich meals.
3. Oral iron education (not a prescription): elemental 40–65 mg once daily or every other day; constipation common.
4. Repeat ferritin/hemoglobin often in 4–8 weeks to confirm response.
