Where do you see rouleaux formation?

Rouleaux formation is the linking of RBCs into chains resembling stacks of coins. Some rouleaux is normal in dogs, and more occurs in normal cats. Increased rouleaux formation in canine blood smears is associated with an increase in fibrinogen or acute phase proteins and is usually seen in inflammatory diseases.

How do you reduce rouleaux formation?
