This study will analyze gene expression data from various biological specimens collected from voluntary participants.
Primary objective is the collection of specimens from volunteers for the development and validation of HostDx tests. The study does only encompass specimen collection - Therefore, no traditional endpoint is defined but rather the successful collection of clinical specimens is defined as the endpoint.
