This post is also available in: हिन्दी (Hindi)

Diagnosis

Hemoptysis diagnosis consists of the following tests:

• Sputum test: The patient is asked to cough out the sputum into a container. Generally from a deep cough and in the morning. Patients are advised to have plenty of fluids to loosen up the secretions. At least 2 milliliters of sputum is required by the laboratory as an adequate sample.

Chest X-ray: shows us changes in the lung parenchyma, associated complications ~ signs of pulmonary infections, or heart failure.

CT Scan of the chest – is carried out to study more minute changes in the lung parenchyma like air trapping, emphysema, bronchiectasis, signs of infection, lung abscess, and others. It also gives a better picture of muscle, other organs, bones, and fat.

Lung function test Spirometer devices are used to assess the pulmonary functioning in form of how long the lung can hold, take in, and move out the air (less air in – restrictive type less air out- obstructive type of lung disease). It is also helpful in the assessment of the ongoing treatment and in grading the seriousness of the disease.

• With the help of Peak flow monitors, we can measure the speed at which the air is being blown out by the lungs.

• Pulse oximetry and arterial blood gas –assessment is done to measure the amount of oxygen in the blood.

Complete blood count (CBC)

Bronchoscopy

Pulmonary angiography to assess blood flow In the lungs, to see the site of bleed.

Lung VQ scan to evaluate blood flow and airflow to the lungs.
