welcome to healthcaremagic.com.An essential part of diagnosing hemoptysis is ruling out hematemesis
(vomiting of blood) and other forms of pseudohemoptysis (blood in the sputum that originates outside of the respiratory tract
). Blood can originate in the back of the mouth (an area known as the oropharynx) or in the gastrointestinal tract.
After confirmation of hemoptysis, diagnosis involves differentiating among the possible causes of the bleeding, from lung cancer
to bronchitis. The diagnosis involves a detailed medical history, laboratory tests, and a chest x-ray. It may also involve a bronchoscopy
or CT scan, depending on the nature of the hemoptysis and likelihood of cancer. If the underlying cause may be related to a vascular disorder (a blood vessel disorder), a pulmonary angiography
may be done.Take care.
