What is the normal serum iron level for adults?

• A. 30-100
• B. 50-150
• C. 70-200
• D. 100-250

Answer: (B)

The normal serum iron level for adults typically ranges from 50 to 150 mcg/dL. This range reflects the amount of circulating iron bound to transferrin in the bloodstream, which is essential for various physiological functions, including the formation of hemoglobin and other iron-containing proteins. Maintaining serum iron levels within this normal range is crucial, as both deficiencies and excesses can lead to significant health issues. Low iron levels may indicate conditions such as iron deficiency anemia, while excess iron could result from conditions like hemochromatosis or repeated blood transfusions. Understanding these ranges is important for diagnosing and managing disorders related to iron metabolism. The other options do not align with the established clinical guidelines for normal serum iron levels in adults.
