listen
with chronic iron deficiency serum iron is low and total iron binding capacity is _.
a) low
b) high
c) normal
d) none of the other choices

Explanation:

In chronic iron deficiency, the body tries to compensate for the lack of iron. Serum iron is low as there is insufficient iron available. Total iron - binding capacity (TIBC) reflects the amount of transferrin (a protein that binds iron). When iron is deficient, the body produces more transferrin receptors, and transferrin levels increase. Since TIBC is a measure related to transferrin (TIBC is approximately equal to the amount of transferrin multiplied by a constant factor as transferrin has two iron - binding sites), an increase in transferrin leads to a high TIBC.

Answer:

B. High
