Overview
Laboratory Tests
Routine Tests
Findings in routine blood tests are based on the severity of the disease and the cause, they can include the following:[1]
- Leukocytosis or leukopenia
- Eosinophilia (in cases of eosinophilic pneumonia)
- Anemia
- Hyponatremia
- Thrombocytopenia
- Elevated BUN
- Findings of lactic acidosis (decreased HCO3, increased lactic acid levels)
Sputum Gram Stain and Culture
- Sputum samples should be obtained of all patients with productive cough
- Gram-stain and culture should be performed to assess the causative agent and guide the therapy.
Other Laboratory Tests
Urine Antigen Test [2]
- Used to diagnose Legionella disease.
- The presence of the antigen in urine can be detected in 24 hours since the onset of the symptoms
- The severity of Legionella disease increases the sensitivity of the urinary antigen test.
