Primary erythrocytosis caused by polycythaemia vera, when the increased red-cell mass is caused by neoplastic proliferation of hematopoietic cells in the bone marrow. Thrombocytosis and leucocytosis may also occur with polycythaemia vera. Secondary erythrocytosis, when the increased red-cell mass is caused by an increased production of ...

Erythrocytosis. Erythrocytosis, sometimes called polycythaemia, means having a high concentration of red blood cells in your blood. This makes the blood thicker and less able to travel through blood vessels and organs. Many of the symptoms of erythrocytosis are caused by this sluggish flow of blood.
The information on the diagnosis of erythrocytosis and polycythaemia vera is based on expert opinion in a British Society for Haematology Guideline for the diagnosis and management of polycythaemia vera [McMullin, 2019a], the BMJ Best Practice guideline Polycythaemia vera [BMJ Best Practice, 2022], an American Family Physician review article Polycythaemia vera: Rapid evidence review [], the ...
The recommended management of all people with polycythaemia vera in secondary care includes: An explanation of the risks and implications of the condition. A patient information leaflet, such as that provided by MacMillan Cancer Support, may be helpful. Venesection to maintain the haematocrit at less than 0.45.
Polycythemia is a blood disorder occurring when there are too many red blood cells, which carry oxygen from the lungs through the blood stream to the rest of the body. The excess red blood cells cause the blood to increase in volume and thicken, keeping it from flowing easily. Polycythemia can be divided into two overarching categories:
Description. Polycythemia (sometimes referred to as erythrocytosis) is defined as an absolute increase in red blood cell (RBC) mass, most commonly suspected in the context of an elevated hemoglobin, hematocrit, or RBC count. Use of age- and gender-based norms is critical, as they fluctuate throughout childhood.

Erythrocytosis describes having too many red blood cells (a solid part) in relation to plasma (the liquid part). 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.
