• Iron: 60-170 mcg/dL
• TIBC: 240-450 mcg/dL
• Transferrin saturation: 20-50%

Note: mcg/dl = micrograms per deciliter

TIBC is usually higher-than-normal when the body's iron stores are low. Higher-than-normal TIBC may mean:

• Iron deficiency anemia
• Pregnancy (late)

Lower-than-normal TIBC may mean:

• Cirrhosis
• Hemolytic anemia
• Hypoproteinemia
• Inflammation
• Liver disease
• Malnutrition
• Pernicious anemia
• Sickle cell anemia

There is very little risk involved with having your blood taken. Veins and arteries vary in size from one patient to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight but may include:

• Excessive bleeding
• Fainting or feeling light-headed
• Hematoma (blood accumulating under the skin)
• Infection (a slight risk any time the skin is broken)
