CT scan of the lungs showing findings diagnostic of<unk> . White and black arrows point to dilated bronchi characteristic of the disease. The goals of a diagnostic evaluation for<unk>  are radiographic confirmation of the diagnosis, identification of potential treatable causes, and functional assessment of the patient. A comprehensive evaluation consists of radiographic imaging, laboratory testing, and lung function testing. Laboratory tests that are commonly part of the initial evaluation include a complete blood count, sputum cultures for bacteria, mycobacteria, and fungi, testing for cystic fibrosis, and immunoglobulin levels. Additional tests that are sometimes indicated include testing for specific genetic disorders. Lung function testing is used for the assessment and monitoring of functional impairment due to<unk> . These tests may include spirometry and walking tests. Obstructive lung impairment is the most common finding but restrictive lung impairment can be seen in advanced disease. Flexible bronchoscopy may be performed when sputum studies are negative and a focal obstructing lesion is suspected. A chest x-ray is abnormal in most patients with<unk> . Computed tomography is recommended to confirm the diagnosis and is also used to describe the distribution and grade the severity of the disease. Radiographic findings include airway dilation, bronchial wall thickening, and atelectasis. There are three types<unk>  that can be seen on CT scan, namely cylindrical, varicose, and cystic<unk> .
