What is the main purpose of an iron panel?

c
To diagnose infections
d
To measure vitamin levels
Which test best reflects how much iron is stored in the body?
a
Serum iron
b
Hemoglobin
c
Transferrin saturation
d
Ferritin
Ferritin reflects iron stores. It is the most useful single test for understanding how much iron the body has available.
Why is serum iron often not the best test to judge iron deficiency by itself?
a
It is rarely measured correctly
b
It changes very little over time
c
It can vary from day to day and with illness or recent meals
Serum iron fluctuates and does not reliably reflect iron stores on its own.
d
It only reflects vitamin levels
Which statement about iron deficiency is true?
a
Iron deficiency always causes anemia
b
Iron deficiency can exist even when hemoglobin is normal
Iron deficiency can be present before anemia develops. That is why iron studies are sometimes abnormal even when hemoglobin is still normal.
c
Iron deficiency only occurs in people with poor diets
d
Iron deficiency cannot be detected with blood tests
What does it usually mean if iron tests change shortly after iron treatment begins?
a
The treatment is not working
b
The tests are unreliable
c
Temporary changes are expected during iron repletion
Iron levels often shift after treatment begins. Doctors focus on trends over time rather than single results.
d
Iron treatment should be stopped
