Hemoglobin and hematocrit are two important components of the complete blood count, a test that a doctor might order to determine whether there are any abnormalities in a patient is blood chemistry. Both hemoglobin and hematocrit refer to specific characteristics of red blood cells, but they measure different things.

The hematocrit test determines how much of the total blood volume contains red blood cells.
