Question

what lab value normally elevates with chronic iron deficiency?
a) hgb
b) ferritin
c) tibc
d) hct

Explanation:

To solve this, we analyze each option:

• Option a (Hgb): Hemoglobin (Hgb) decreases in iron deficiency anemia, so it's incorrect.
• Option b (Ferritin): Ferritin (iron storage protein) decreases in chronic iron deficiency, so it's incorrect.
• Option c (TIBC): Total Iron - Binding Capacity (TIBC) increases in chronic iron deficiency because when iron is low, the body tries to bind more iron, so TIBC elevates.
• Option d (HCT): Hematocrit (HCT) decreases in iron - deficiency anemia, so it's incorrect.

Answer:

c) TIBC
