sputum

Semiliquid diagnostic 'goo' obtained from deep coughs from the lungs, bronchi, trachea, which is collected sterilely and examined by cytology and/or cultured Complications Laceration of coronary arteries, or liver due to puncture, arrhythmias caused by needle irritation, vasovagal arrest, pneumothorax, infection.

Sputum–diagnostic utility
Cytologic examination Specimen is smeared on a glass slide, stained with one of several dyes, and examined by LM; the only cells seen in normal sputa are those of tracheobronchial tree and lungs.
Culture & sensitivity The specimen is swabbed on a culture plate in the microbiology laboratory to detect the growth of potentially harmful bacteria or fungi

Precancerous exfoliated cells can be routinely identified in pathology departments by cytologic examination of washings or brushings from bronchi, oral cavity, esophagus, stomach, bile and pancreatic ducts, sputum and urine; however, the detection of exfoliated cancer cells by routine cytopathological examination is limited because of the presence of few atypical cells in specimens, the difficulty of distinguishing low grade dysplasias from non-specific reactive or inflammatory changes, and the low sensitivity and specificity of the available diagnostic methodology.
