The hematocrit is the proportion, by volume, of the blood that consists of red blood cells. Learn the significance of normal, high, and low hematocrit values, and symptoms.
What’s the normal range for hematocrit levels? Here are normal hematocrit levels by sex and age: Adults assigned male at birth (AMAB): 41% to 50%. Adult assigned female at birth (AFAB): 36% to 44%. Infants: 32% to 42%. Newborns: 45% to 61%. Talk to your healthcare provider if you take hormone therapy, as your lab results may look different.
A hematocrit test can help your health care team make a diagnosis or monitor how you respond to a treatment. The test is done as part of a complete blood count (CBC). When the hematocrit value is low, the proportion of red blood cells in the blood is lower than usual.
Learn about the hematocrit (HCT) blood test, the normal levels, and how it is used to diagnose conditions such as anemia, leukemia, and iron deficiency.
A typical hematocrit range in adults is 36–54%. However, age, sex, and health conditions can influence hematocrit levels. Low red blood cell levels can indicate conditions such as anemia.
But, in general, normal levels are: For men and people assigned male at birth: 38.3% to 48.6%; For women and people assigned female at birth: 35.5% to 44.9%; Low Hematocrit
Normal values for the hematocrit test vary according to age, sex, pregnancy, the altitude where people live, and even vary slightly between various testing methods. The following chart is reported ranges of normal hematocrit levels by ages and high-altitude residents.
Normal hematocrit levels vary based on age and race.. In adults, normal levels for men range from 41%-50%. For women, the normal range is slightly lower: 36%-44%. A hematocrit level below the normal range, meaning the person has too few red blood cells, is called anemia.
The HCT of a healthy adult male is typically between 40% and 54%, and that of a female is 36% to 48%. [2] . Although these 2 methods are still in use in some primary care settings and medical teachings, they are widely replaced in most settings by an automated analyzer, where HCT reports are generated along with the complete blood count.
