What is the meaning of HCT?
The amount of whole blood that is made up of red blood cells. It depends on the number and size of red blood cells. A HCT test is usually part of a complete blood count (CBC). It may be used to check for conditions such as anemia, dehydration, malnutrition, and leukemia.
What does HCT mean in a blood test when it is high?
If you’ve taken a hematocrit test and hematocrit is high, this means that you have more red blood cells than what’s considered to be healthy. High hematocrit levels could indicate underlying medical conditions like: Dehydration. Carbon monoxide poisoning. Congenital heart disease.
What level of HCT is concerning?
For men, a hematocrit level of less than 41% is considered anemic. For women, that number is slightly lower at less than 36%.
What does HCT and HGB mean?
Hemoglobin and hematocrit are both red blood cell measurements that are used to help diagnose nutritional deficiencies, acute illnesses, and chronic medical conditions. Hemoglobin is a protein in the red blood cells (RBCs), and hematocrit reflects the percentage of blood volume that is composed of red blood cells.
What happens if HCT is low?
A low hematocrit level means the are too few red blood cells in the body. In these cases, a person may experience symptoms that signal anemia. Common symptoms include fatigue, weakness, and low energy.
What causes low HCT?
Causes of low hematocrit, or anemia, include: Bleeding (ulcers, trauma, colon cancer, internal bleeding) Destruction of red blood cells (sickle cell anemia, enlarged spleen) Decreased production of red blood cells (bone marrow supression, cancer, drugs)
What level of HCT is dangerously high?
Hemoglobin levels greater than 16.5 g/dL (grams per deciliter) in women and greater than 18.5 g/dL in men suggest polycythemia. In terms of hematocrit, a value greater than 48 in women and 52 in men is indicative of polycythemia.
What is the most common cause of elevated hematocrit?
Dehydration, the most common cause of a high hematocrit.

What can I do to increase my low hematocrit? Increasing the consumption of red meat (liver in particular), fish and shellfish (oysters, clams, shrimp, and scallops), dried fruit (apricots, prunes, and peaches), green leafy vegetables, beans, iron fortified breads and cereals, all rich in iron, may help.
What level of hemoglobin is dangerously low?
What hemoglobin levels are considered severe or dangerously low? A hemoglobin level of less than 5.0 grams per deciliter (g/dl) is dangerous and could lead to heart failure or death. A normal hemoglobin level is 13.2–16.6 grams per deciliter (g/dL) for males and 11.6–15 g/dL for females.

- Congenital heart disease.
- Exposure to high altitude.
- Failure of the right side of the heart.
- Low levels of oxygen in the blood.
