What does Erythrocytosis mean?
Erythrocytosis is when you have more red blood cells than normal. Red blood cells are also called erythrocytes. Red blood cells carry oxygen throughout your body and remove carbon dioxide from your body. Your bone marrow (the tissue inside your bones) makes red blood cells and releases them into your bloodstream.

What does polycythemia vera mean?

What are the different types of apheresis?
Types
- Plasmapheresis – blood plasma.
- Erythrocytapheresis – red blood cells.
- Plateletpheresis (thrombapheresis, thrombocytapheresis) – blood platelets.
- Leukapheresis – leukocytes (white blood cells).
- Stem cell harvesting – circulating bone marrow cells are harvested to use in bone marrow transplantation.

What does Sideroblastic mean?

Normally, sideroblasts are present in the bone marrow, and enter the circulation after maturing into a normal erythrocyte.
