Rouleaux formation on wet smear. Rouleaux (singular is rouleau) are stacks or aggregations of red blood cells (RBCs) that form because of the unique discoid shape of the cells in vertebrates.
Red blood cells (RBCs), referred to as erythrocytes (from Ancient Greek erythros ' red ' and kytos ' hollow vessel ', with -cyte translated as 'cell' in modern usage) in academia and medical publishing, also known as red cells, [1] erythroid cells, and rarely haematids, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen (O 2) to the body tissues ...
Erythrocyte aggregation is a physiological phenomenon that takes places in normal blood under low-flow conditions or at stasis. The presence or increased concentrations of acute phase proteins, particularly fibrinogen, results in enhanced erythrocyte aggregation.
Erythrocyte deformability is an important determinant of blood viscosity, hence blood flow resistance in the vascular system. [3] It affects blood flow in large blood vessels, due to the increased frictional resistance between fluid laminae under laminar flow conditions.
There are multiple methods of washing red cells. [2] These can include automated or manual methods. They can use centrifugation or centrifugation-free methods. [2] The red cells can be re-suspended in saline or other types of special preservative solutions for red cells, such as SAGM (saline, adenine, glucose and mannitol).
Automatic ESR analyzer with specialised tube. The erythrocyte sedimentation rate (ESR or sed rate) is the rate at which red blood cells in anticoagulated whole blood descend in a standardized tube over a period of one hour.
Anisopoikilocytosis is a medical condition illustrated by a variance in size (anisocytosis) and shape (poikilocytosis) of a red blood cell.The underlying cause can be attributed to various anemias, most often; beta thalassemia major, a form of microcytic anemia. [1]
Australia learned about Chinese live-fire naval drills off the country’s coast that forced dozens of flights to be diverted via an alert from a commercial pilot, authorities said on Monday.
