Sputum

 

pathological secretions from the respiratory tract that are discharged with a cough; they are the product of the overactivity of the mucous glands. Sputum often contains epithelial cells, bits of lung tissue, blood, and pus. The amount of sputum, as well as its appearance, is important in the diagnosis of disease.

Sputum may be mucous, purulent, serous, bloody, or mixed. Rusty sputum (sputum mixed with and colored by blood) is a sign of lobar pneumonia. Abundant purulent sputum is characteristic of a ruptured abscess in the lungs. Gray, dirty, malodorous sputum appears when there is putrefactive decomposition of lung tissue.

Sputum may be examined in a laboratory with the aid of a microscope and also by bacteriological and cytological analyses. Laboratory examination makes it possible to detect pathogenic microorganisms (including the causative agent of tuberculosis), cells of malignant tumors, and certain other elements that are characteristic of certain diseases, and to determine the sensitivity of bacterial flora to antibiotics.
