Overview
Other diagnostic studies helpful in diagnosing Farmer's lung disease include Pulmonary function tests, Bronchoalveolar lavage-microscopy, and rarely lung biopsy
Other Diagnostic Studies
Other diagnostic studies useful in diagnosing Farmer's lung disease include Pulmonary function tests, Microscopy of bronchoalveolar lavage and rarely lung biopsy.
Pulmonary function tests show-
- Restrictive pattern
- Decreased diffusion capacity of lung
- Hypoxemia at rest or with exertion[1]
In acute cases-
- little or no impairment of gas flow
- decreased compliance and V/Q imbalance leading to hypoxemia and impaired gas exchange.
In chronic cases-
- Increased compliance
- stiff lungs- restricted volume
Microscopy of broncho alveolar lavage shows- leukocytosis
Rarely, lung biopsy is done if diagnosis could not be made with other investigations and no other criteria is met. Trans bronchial biopsy is sufficient for the diagnosis.
