What causes serosanguinous fluid?

Serosanguinous fluid is a mixture of serum and blood, typically resulting from the leakage of plasma and red blood cells from damaged blood vessels. This type of fluid commonly occurs in inflammatory processes, such as in wounds, surgical sites, or infections, where tissue damage leads to increased vascular permeability. Conditions like trauma, surgical interventions, or certain medical conditions can also contribute to the formation of serosanguinous fluid. Its presence may indicate an underlying issue that warrants further investigation.
