Blood-Tinged Sputum Overview

Blood-tinged sputum is expectorated mucous matter from the airways that is tinged or streaked with blood. The blood can be either bright red or dark red in color. It’s also referred to as blood-streaked sputum, or sputum contains blood.

Blood-tinged sputum is different from coughing up blood with or without very little sputum (hemoptysis). Hemoptysis can be a potentially life-threatening condition requiring immediate medical attention. Sputum that is streaked with blood may be due to something as benign as irritation of upper-airway passages due to dry, ambient air. It may be a sign of a more serious medical condition, like pneumonia or a blood clot in the lung, especially if accompanied by other symptoms.
