According to the Mayo Clinic, a normal hematocrit test result ranges from 34.9 to 44.5 percent for women and 38.8 to 50 percent for men. In women, a normal amount of hemoglobin is between 12.0 and 15.5 gram per deciliter of blood. Men's readings should be 13.5 to 17.5 grams.
An abnormal test result often indicates an iron deficiency, or anemia, because iron is needed to make red blood cells, MedlinePlus explains. To check iron count, doctors typically order two blood tests. A hematocrit test checks the percentage of red blood cells in blood, while the amount of hemoglobin protein in blood is also measured.
