How do you know if you have a lung infection?
Other tests for lung infections, such as pneumonia and acute bronchitis, may include:
- Blood tests or cultures.
- Oximetry.
- Arterial blood gases.
- Bronchoscopy.
- Transtracheal mucus cultures (rarely done).
- Lung biopsy.
- Thoracentesis.
- Computed tomography (CT) scan.
Can blood test detect lung problems?
