How is Pneumonia diagnosed by a doctor?

Diagnosis typically involves a physical exam where the doctor listens to the lungs with a stethoscope. What specific tests, like chest X-rays, blood tests, or sputum tests, are used to confirm pneumonia and identify the causative organism?

Following a physical exam, doctors use specific tests to confirm pneumonia and identify its cause. A chest X-ray is the primary tool to visually confirm the presence and location of lung infection. Blood tests, such as a complete blood count (CBC) and blood cultures, help assess the severity of infection and check if bacteria have entered the bloodstream. To identify the specific organism, a sputum test (culture and Gram stain) analyzes mucus coughed up from the lungs to detect whether bacteria are present and which antibiotics might work. In severe or puzzling cases, advanced tests like a pulse oximetry to measure blood oxygen levels or a CT scan for a more detailed view may be used to guide appropriate treatment.

To confirm pneumonia, doctors often start with a chest X-ray to check for lung inflammation or fluid buildup. Blood tests help detect infection and sometimes identify whether it’s viral or bacterial. A sputum test, where mucus from your lungs is analyzed, can show which specific germ is causing the infection, guiding antibiotic treatment if needed. In more severe cases, doctors may use CT scans or pulse oximetry to assess lung function and oxygen levels. These tests together help ensure accurate diagnosis and the right treatment plan.
