Rouleaux formation occurs when red blood cells form rolls or stacks. If not due to an artifact, such as a result of not preparing the blood smear soon enough after placing the blood on the slide, it may be due to the presence of high concentrations of abnormal globulins or fibrinogen. This formation is found in multiple myeloma and macroglobulinemia.
The red blood cells stack up like coins. http://en.wikipedia.org/wiki/Rouleaux
Autoagglutination should also be distinguished from "Rouleaux formation" wherein normal blood tends to form stacks on keeping, which disperses on dilution with normal saline.
Rouleaux refers to the stacking of red blood cells (erythrocytes) in human blood. Rouleaux formation is enhanced in the presence of increased plasma proteins, leading to an increased erythrocyte sedimentation rate (ESR).
Multiple Myeloma
Rouleaux formation, which is the stacking of red blood cells, does not typically occur in vivo due to the flow dynamics in blood vessels. The force of blood flow helps to separate and prevent red blood cells from sticking together. Additionally, the presence of plasma proteins like albumin helps to maintain the cells in a dispersed state.
I'm not familiar with the term "roulex formation." It could be a typo or a specific term used in a certain context. If you provide more information or clarify the context, I may be able to help further.
rouleaux
Spring rolls are "des rouleaux de printemps".
The condition is called "Rouleaux".
"Rollers" about surf-waves, for hair, or in painting, "rolling pins" in pastry, and "rolls" of paper, scrolls, and wallpaper are English equivalents of the French word rouleaux. Whatever the meaning or use, the pronunciation remains "roo-lo" in French.
literally "un lit traîneau", but the old bed style "lit à rouleaux" also seems to fit.
