Best Answer

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.

Why rouleaux formation does not occur in vivo?

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.
