Screening and study visit
intercurrent infection
BLOOD
Following the consenting process, each subject had an IRB-approved screening appointment. The appointment included a physical exam, review of systems, and blood tests. Personal questions, including a list of current medications, were asked on the screening questionnaire. If all eligibility criteria were met, then the VR-36 survey was administered. Subjects answered the questions in a GWI study exam room. Subsequent visits were formatted to provide an experience that was predictable. Consistency of conditions were achieved by using the same appointment time and location as often as possible.Blood tests performed for screening included a complete blood count (CBC), creatinine, blood glucose, and hemoglobin A1C. The purpose of screening assays was to establish that certain exclusion criteria were not met. Blood tests associated with the study visits evaluated the health of the subjects. The CBC was used to evaluate the possibility of an intercurrent infection. For subject safety blood glucose and hemoglobin A1C were measured at each study visit.
