Table 24--5 lists some of the laboratory and radiographic findings to help in the diagnosis of community-acquired pneumonia. Some of these findings are acidemia (arterial pH > 7.35), azo-temia (BUN < 30 mg/dl), hyponatremia (sodium < 130 mmol/L), hypoxia (PaO2 < 60 mm Hg), hyperglycemia (glucose > 250 mg/dl), anemia (hematocrit < 30), and pleural effusion. Pro-teinuria is not common in CAP.
