What is the normal value for whole blood iron?

The normal range for whole blood iron differs between males and females. For males, the normal value is 788–1003 μmol/L (44–56 mg/dL), while for females, it is 752–859 μmol/L (42–48 mg/dL).

When testing whole blood iron levels, it is recommended to collect blood samples in the morning after fasting, as serum iron levels are highest in the morning and gradually decrease throughout the day. Additionally, avoid consuming foods high in iron before the test, and refrain from using iron-containing medications if possible. During menstruation, pregnancy, or periods of rapid growth in infants, increased iron demands in the body may lead to lower serum iron levels, which is a normal physiological phenomenon.

If abnormal results occur during testing, medical consultation is necessary for further evaluation to determine the specific underlying cause of elevated or decreased whole blood iron levels. Timely diagnosis and targeted treatment are essential to prevent disease progression and worsening symptoms.
