Labadie Test

The Labadie test is a pulmonology (lung medicine) measurement technique that can be used to quantify so-called inspiratory airway obstruction (obstruction of the upper airway in particular during inspiration). The test consists of measuring the forced inspiratory vital capacity (FIVC). The FIVC is the lung volume that can be forcefully inhaled at one time after maximal expiration (exhalation).

Indications (areas of application)

  • Bilateral recurrent nerve palsy – The recurrent laryngeal nerve is a nerve that innervates the muscles responsible for vocal fold movement and is thus involved in voice production. If this nerve is injured on one side, it results in hoarseness due to decreased mobility within the larynx. If the nerves are affected on both sides, this can lead to dyspnea (shortness of breath).

The procedure

The Labadie test is performed as part of the spirometric examination (pulmonary function) of the lung volumes.

Possible complications

  • None
