For inpatients with pneumonia, it is advisable to perform blood culture, and sputum gram smear and culture tests before antibiotic administration as long as they are indicated. Sputum tests must be done using sputum samples obtained before antibiotic administration, and should only be performed when sufficient amounts of sputum are released, collected, transferred, and treated [76] . For patients with moderate community-acquired pneumonia, a blood culture, Legionella, S. pneumoniae urinary antigen test, and sputum gram smear and culture must be performed [77] [78] [79] . For patients with airway intubation, a test using trans-tracheal aspi-rate samples must be performed. For immunodeficient patients, or patients for whom common treatments have failed, invasive tests such as airway endoscopy and percutaneous pulmonary aspiration are useful [80, 81] .
