The practical interest of the direct measurement of the red blood cell volume in clinical haematology remains a matter of discussion. A retrospective study of 385 cases with high haematocrit values shows that the measurement of RBC volume is useful for the diagnosis between true and spurious polycythemia only when the haematocrit value is slightly increased (until 52 p.cent in women and 55 p.cent in men). At the higher values of haematocrit, the direct measurement of the RBC volume does not help for the diagnosis between primitive and secondary polycythemia, but may be useful for the choice of the treatment.

Structure and Function of Erythrocytes

There are between 4.2 and 6 million erythrocytes, also known as red blood cells, in every microliter of blood. These cells are small, flattened biconcave discs with centers that are depressed.
The erythrocyte plasma membrane is associated with proteins such as spectrin, which forms a flexible cytoplasmic meshwork. This meshwork allows erythrocytes to twist, turn, become cup-shaped, and regain their biconcave shape as they pass through narrow capillaries. Additionally, erythrocytes can form...

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
