Diagnosing Iron Deficiency
What happens during a physical examination?1
Some of the questions your doctor may ask you are:
What type of tests will your doctor prescribe?2
Iron is stored in the body as ferritin and is delivered throughout the body by transferrin (a protein in blood that binds to iron). A doctor may check blood levels of these two components if anaemia is suspected.
The usual tests needed are:1
Typical iron levels in an adult3-4
|Hemoglobin, g/dL||>13 (men),> 12(women)|
|Mean corpuscular volume (MVC), fL||80-95|
|Serum iron, nmol/L||10-30|
|Serum ferreting, μg/L||15-200 (premenopausal woman), 20-300 (men and postmenopausal women)|
|Totall iron-binding capacity (TIBC), μmol/L||45-81|
