In diagnosis, the definitive sign of an abscess of the lung is the aspiration of pus from the abscess. This fluid is obtained from your lung using a syringe and is examined microscopically and cultured to obtain the causative organism. The culture can also be used to identify the appropriate antibiotic to use. Your doctor will also carry out a chest examination to determine where the abscess is located before attempting to drain it.
