Learn what hematocrit blood test is and what it can mean if you have abnormal Hct levels. Find out common causes of low or high hematocrit levels and how to address some of the issues that are associated with low or high Hct range.


Potential causes of a high hematocrit level include dehydration, smoking, living at high altitudes, lung disease, congenital heart disease, polycythemia vera or a erythropoetin-producing tumor in the kidney. Dehydration is the most common cause, and when there is enough fluid intake, the hematocrit returns to normal levels.


Hematocrit blood testing is performed to determine the number of red blood cells in a person's blood. Low or high hematocrit levels may signal disease. Understand the normal hematocrit range, and what an abnormal (high or low) reading might be saying about your blood and your health.


A high hemoglobin count indicates an above-normal level of the iron-containing protein in red blood cells. Hemoglobin (often abbreviated as Hb or Hgb) is the oxygen-carrying component of red blood cells. Hemoglobin, which gives red blood cells their color, helps carry oxygen from the lungs to the rest of the body and carbon dioxide back to the ...


Symptoms Of High Levels Of Hemoglobin Or Red Blood Cells. Polycythemia, the opposite of anemia, is a condition in which there is an excess of red blood cells and high hemoglobin levels. In case you have polycythemia, you may experience headaches, dizziness, problems with vision, and flushing.


Learn about hematocrit (hct) levels in the blood. Low or high hematocrit levels may signal conditions such as anemia, bone marrow problems, dehydration, and more. Learn the significance of normal, high, and low hematocrit values.


Hemoglobin is the oxygen-carrying protein that is present in the red blood cells, whereas hematocrit is the percentage of the volume of blood that is made up of red blood cells. The following write-up provides information on the circumstances under which a person may have high hemoglobin and hematocrit.


Your hematocrit level is the amount of red blood cells present in your blood. For adult males, it should be around 45% of your blood; for adult females, around 40%. The hematocrit level is an important determining factor in diagnosing different illnesses. High hematocrit levels are commonly caused by lung and heart disease, as well as dehydration.


Hematocrit (also called HCT, packed cell volume, or PCV) is measured by routine lab tests. It is the percentage of red blood cells in your blood or, in other words, the volume of red blood cells divided by the total blood volume [1, 2, 3].Red blood cells come from the bone marrow, where they differentiate from (are made from) stem cells.


What does HCT mean in a blood test? Since you found this page you’re probably wondering what is HCT in your blood test. When you get blood work done many tests will assess your HCT levels (the CBC test being the most common test to do this).. HCT stands for Hematocrit. (Other names for HCT are Packed Cell Volume (PCV) and Erythrocyte Volume Fraction (EVF)).
