Several tests can help diagnose a chest infection. The most common include a chest X-ray, blood tests, and pulse oximetry.
Diagnostic Tests for Chest Infections
Here's a breakdown of common tests used to diagnose chest infections:
- Chest X-ray: This is a primary imaging technique used to visualize the lungs and look for signs of inflammation or infection, such as pneumonia. A chest X-ray can reveal abnormalities in the lung tissue.
- Blood Tests (Complete Blood Count - CBC): Blood tests, like a CBC, are performed to assess the body's immune response to infection. Elevated white blood cell counts often indicate an active infection.
- Pulse Oximetry: This non-invasive test measures the oxygen saturation in your blood. Low oxygen levels can be a sign of impaired lung function due to infection.
Additional Tests (Depending on the situation)
- Sputum Test: If you're coughing up mucus (sputum), a sample can be analyzed to identify the specific bacteria or virus causing the infection.
- Arterial Blood Gas (ABG): Measures the levels of oxygen and carbon dioxide in your blood. It is used to assess the severity of respiratory problems.
