@id 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
