Definition
Blood-tinged sputum expectorated mucous matter from the airways (lungs, nose, mouth or upper airways) that is tinged or streaked with blood. The blood can be either bright red or dark red in color.
Alternative Names
Blood-streaked sputum, sputum contains blood.
Synopsis
Blood-tinged sputum is distinguished from frank hemoptysis—or coughing up blood without or with very little sputum—which 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, or it may a sign of a more serious medical condition, such as pneumonia or a blood clot in the lung, especially if accompanied by other symptoms.
