Hematocrit is the ratio of the volume of red blood cells to the total amount of blood in a sample. Red blood cells are essential to health because they transport oxygen and nutrients across the body. To remain healthy, you need the correct hematocrit levels. Several conditions can cause hematocrit to be too high or low.

1. What is a normal hematocrit level?

The normal range for hematocrit depends on both gender and age. Since hematocrit levels change quickly as children age, there is a completely separate set of average hematocrit levels against which doctors will compare samples taken from children. The typical hematocrit range for adult men is between 38 and 50 percent, while adult women typically range from 34 to 44 percent.
