Answer

Since history and physical examination alone may not be adequate to make a diagnosis in cases of silent aspiration, additional diagnostic tests, such as the following, may be needed:

  • Transnasal esophagoscopy

  • Cervical auscultation

  • Blood tests: Including thyroid-stimulating hormone, vitamin B-12, and creatine kinase; may be useful, especially in neurogenic dysphagia

  • Imaging studies: May include videofluoroscopy, computed tomography (CT) scanning, magnetic resonance imaging (MRI), and chest radiography

  • Endoscopic examination

  • Esophageal pH monitoring: The criterion standard for diagnosing reflux disease

  • Pulmonary function tests

See Workup for more detail.
