Stridor: Diagnostic Tests

Optional medical device diagnostics – depending on the results of the history, physical examination, and obligatory laboratory parameters – for differential diagnostic clarification.

  • Spirometry (basic examination within the scope of pulmonary function diagnostics) – if pulmonary function limitation is suspected.
  • X-ray of the thorax (X-ray thorax/chest), in two planes – for orienting imaging of the heart and lungs.
  • Computed tomography of the thorax / chest (thoracic CT) – to exclude tumors.
  • Thyroid sonography (ultrasound examination of the thyroid gland) -as a basic examination to determine the size of the thyroid gland and thyroid volume, as well as any structural changes such as nodules; if necessary, with fine needle biopsy – if thyroid disease is suspected.
  • Thyroid scintigraphy – if thyroid disease is suspected.
  • Laryngoscopy (laryngoscopy) – when diseases of the larynx are suspected.
  • Bronchoscopy (pulmonary endoscopy) – when structural lung diseases are suspected.
