Iron Profile With Transferrin Saturation

You should get an iron profile with transferrin saturation test if you have fatigue, weakness, pale skin, hair loss, brittle nails, or shortness of breath, or if a CBC shows anemia. It is also recommended for pregnant women, people with heavy periods or chronic blood loss, and those with suspected iron overload or hemochromatosis, or on iron therapy.

Fasting for 8–12 hours is recommended before an iron profile test, and you may drink water during this time. Give your sample in the morning, when iron levels are highest. Avoid iron supplements for at least 24 hours before the test, and inform your doctor about any medicines, recent blood transfusions, or pregnancy.
