What tests should be done for interstitial lung disease
Interstitial lung disease is a major cause of complication or secondary pulmonary fibrosis, so it should be prevented as soon as possible. one is that when there is a slight activity, such as rapid breathing, and self-feeling of twisted pronunciation, wet rales and other phenomena, we should actively carry out examination. Interstitial lung disease (ILD) was identified and excluded by chest X-ray, chest X-ray, CT, bronchoalveolar lavage, lung function test, lung biopsy and so on.
CT examination of interstitial lung disease
In chest X-ray or chest X-ray, patients with ILD may have diffuse shadow, or rare nodular interstitial shadow, and the lung volume is normal. Special places will also have bronchial wall thickening, peribronchovascular space protruding, regular or irregular small shadow, small peripheral annular shadow and so on.
CT examination is also one of the effective methods for early detection of interstitial lung disease. We can see that there are irregular line grid changes and cystic small air cavities. If it is in the early stage, these small air cavities are under the pleura, and these small air cavities are connected to each other to form obvious subpleural lines. Combined with restrictive ventilatory dysfunction and reduced diffusivity in pulmonary function tests, interstitial lung disease was verified.

Then bronchoalveolar lavage and lung biopsy are further classified from cytological, etiological, biochemical and inflammatory tests, and tracheal cell lavage fluid (BALF) can be used for lavage. According to the proportion of cells in the immune effect of BALF, we can determine whether interstitial lung disease is lymphocytosis or neutropenia. Laboratory tests showed non-specific changes, such as arterial blood gas showing hypoxemia, accelerated erythrocyte sedimentation rate, increased blood lactate dehydrogenase and immunoglobulin.
