Overview
There are laboratory tests that are helpful for diagnosis the underlying cause of hemoptysis. Sputum must be evaluated for the cytology, gram stain, culture, and acid-fast stain.
Laboratory Findings
- There are laboratory tests that are helpful for diagnosis the underlying cause of hemoptysis.
- Sputum analysis provides valuable information about the cause of hemoptysis. Sputum must be evaluated for the followings:
- Laboratory tests that might be abnormal in a patient with hemoptysis:
- Arterial blood gases might show:
- Blood urea nitrogen might be elevated (normal BUN 8 to 20 mg/dL)
- Creatinine might be elevated (normal Cr 0.5 to 1.0 mg/dL for women and 0.7 to 1.2 mg/dL for men)
- Complete blood count (CBC) might show:
- Coagulation studies might show:
- Elevated prothrombin time (normal PT 11-14 sec)
- Elevated partial thromboplastin time (normal aPTT 20-40 sec)
- Urinalysis might show:
- Electrolytes
