IPF: Diagnosis Make an Appointment Refer a Patient Ask a Question Reviewed by Jeffrey James Swigris, DO, MS (September 01, 2017) The first step in diagnosing IPF is a thorough evaluation. Idiopathic pulmonary fibrosis can be diagnosed only after ruling out other lung diseases. When the diagnosis of IPF is suspected, your doctor may have you do a number of tests. These may include: A complete medical history A complete physical examination Chest imaging, including a chest X-ray and high resolution computed tomography (HRCT) scan Pulmonary function tests Arterial blood gas Exercise test and/or an assessment of blood oxygen levels during exertion Blood tests looking for hints at the cause of the lung disease Bronchoscopy with bronchoalveolar lavage Surgical lung biopsy Your doctor may order other tests based on your history and physical exam. You and your health care provider may choose to have you seen by a specialist, such as a pulmonologist (lung specialist) to confirm a diagnosis and treat your IPF once it’s diagnosed.
