Decreased Hematocrit: Causes of Decreased Hemoglobin Levels

Question: What causes decreased hematocrit?

Hematocrit is measurement of the red blood cells in the blood. Hematocrit can be measured by taking a sample of blood and processed in a pathological laboratory.

Red blood cells carry oxygen to cells and tissues of the body. They are made up of hemoglobin which is a oxygen carrying molecule. Hemoglobin binds the iron and oxygen molecule which gives the red color to the blood cells.

Decreased hematocrit levels or hemoglobin may indicate anemia such as iron deficiency anemia.
