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. This can indicate:
By Mayo Clinic Staff. A high hemoglobin count occurs most commonly when your body requires an increased oxygen-carrying capacity, usually because: You smoke. You live at a high altitude and your red blood cell production naturally increases to compensate for the lower oxygen supply there.
What does it mean if your hematocrit is high? A high hematocrit level may be a sign of several conditions, including polycythemia vera . Your healthcare provider is your best resource for information about your test result.
A high hematocrit test result above 48.6% (in men) or 44.9% (in women) is considered above normal and may indicate a blood disorder or other medical condition.
The body might make more red blood cells as a response to conditions that result in low oxygen levels. These might include: Hemoglobinopathy, a condition present at birth that reduces red blood cells' ability to carry oxygen. Living at high altitudes.
In this article, we provide practical diagnostic algorithms that address frequently encountered conditions associated with CBC abnormalities including anemia, thrombocytopenia, leukopenia, polycythemia, thrombocytosis, and leukocytosis.
The referral to a hematologist can help you discern the cause of your high platelet numbers. There are two possible causes: Essential thrombocytosis is due to an underlying problem where the bone marrow starts making too many platelets on its own. Some physicians also call this primary thrombocytosis.
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.
My primary care doctor in reviewing several years worth of lab work this past week noticed a pattern - high hematocrit, high red blood cell count and low lymphocyte count. He diagnosed me with what he called, “thick blood”.
Erythrocytosis causes you to have high levels of hematocrit and/or hemoglobin. Hematocrit levels: Hematocrit is the number of red blood cells you have. Hemoglobin levels: Hemoglobin is an essential protein found in red blood cells. Erythrocytosis is also commonly called polycythemia.
