What is the normal range for hemoglobin and hematocrit?

Normal hemoglobin for adult males is 14 to 18 grams per deciliter, and for adult females is 12 to 16 grams per deciliter. Normal hematocrit for males is 42 to 52 percent, and for females is 37 to 47 percent. Hematocrit is roughly three times the hemoglobin value. Low values indicate anemia from blood loss, iron deficiency, chronic disease, or bone marrow suppression. Elevated values occur in dehydration, polycythemia, and chronic hypoxia. In fluid volume deficit, both values are falsely elevated from hemoconcentration.
