The sensitivity of and yellowish or greenish sputum used as a test for a bacterial infection was 0.79 (95% CI 0.63–0.94); the specificity was 0.46 (95% CI 0.038–0.53).

The ways to tell bronchitis and pneumonia apart are typically you would need to obtain an x-ray, a chest radiograph to determine if there are signs of consolidation or infiltrate on the chest radiograph. If that is found, typically that is more consistent with pneumonia.
