Iron deficiency

Low iron stores in the body. Because iron is needed to carry oxygen in the blood, a deficiency can lead to anemia, fatigue, and weakened immune defenses. Blood testing detects the deficiency before it causes debilitating symptoms.

Early detection matters

Our comprehensive check-up screens for iron deficiency and hundreds of other conditions.

Related biomarkers we test

Red cell distribution width (RDW-CV)

Red Cell Distribution Width (Coefficient of Variation) measures the variation in red blood cell size. Elevated values indicate greater variation in cell size (anisocytosis) and can help diagnose certain anemias.

Mean corpuscular hemoglobin concentration (MCHC)

Mean Corpuscular Hemoglobin Concentration measures the average concentration of hemoglobin in a given volume of red blood cells. It helps distinguish between different types of anemia and assess cell hydration status.

Mean corpuscular hemoglobin (MCH)

Mean Corpuscular Hemoglobin measures the average amount of hemoglobin per red blood cell. It helps evaluate the hemoglobin content of cells and is used alongside other RBC indices to classify anemias.

Hemoglobin

Hemoglobin is a protein in red blood cells that binds to oxygen in the lungs and delivers it to tissues throughout the body. It also plays a role in transporting carbon dioxide back to the lungs for exhalation.

Transferrin saturation

Transferrin saturation is the percentage of transferrin that is bound with iron. It reflects how much of the transport protein is being used.

Transferrin

Transferrin is a liver-produced protein that transports iron in the blood to various tissues. It binds and carries iron to where it's needed.

Iron

Iron is an essential trace element involved in the production of hemoglobin and the transport of oxygen in the blood. In circulation, most iron is bound to the protein transferrin.

Ferritin

Ferritin is a protein that stores iron and releases it when needed. Ferritin levels in the blood reflect the body's iron storage.
