Defining a PD-specific Breath Fingerprint of Underlying Inflammatory and Neurodegenerative Processes

Participants will have two to three tablespoons (30 cc) of peripheral blood drawn to test for inflammatory markers.

Participants will be asked to breathe into the Breath Sampler containing a rapid passive volatile organic compounds (VOC) sampling device. A disposable mouthpiece is placed over a portion of the sampler where the participant placed his/her mouth. The mouthpiece will be disposed of after each use and a new one will be used for each participant. Prior to sample collection, the participant will be asked to rinse his/her mouth with water. Then the participant will breathe deeply into the sampler five times with breaths being five minutes apart to collect the alveolar breath.
