X-rays of the chest, examination of the blood and sputum for infectious microorganisms, and blood tests are commonly used to diagnose individuals with suspected CAP based upon symptoms and physical examination.Chest x-rays and chest computed tomography can reveal areas of opacity which represent consolidation.Blood cultures can be drawn to isolate any bacteria or fungi in the blood stream.
