Iron (Fe)


This blood test measures Iron levels. Iron is an essential nutrient needed in small amounts to help develop healthy red blood cells (RBC) and is found in all living organisms. Iron is a critical component of hemoglobin, the protein in red blood cells that binds oxygen in the lungs and releases it as blood travels throughout the rest of the body.

The human body closely controls iron uptake. Heavy metal toxicity, lack of iron containing foods and genetic defects may disrupt or impair the synthesis of iron in the body. Common symptoms associated with low iron levels are fatigue, depression, impaired learning, cognitive decline, poor memory, irritability, poor coordination, difficulty swallowing, shortness of breath, heart palpitations, joint pain, leg cramps, sores on the skin, poor wound healing, hair loss, headaches, burning tongue, numbness and tingling, and chronic bladder infections, to name a few.

Test Preparation For Optimal Results:

If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.

Disclaimer: A health care provider should evaluate a deviation from normal ranges.
