About this study

Researchers are testing whether providing doctors with genetic information about patients before surgery helps them make better decisions. The trial will involve adults scheduled for elective surgeries at the University of Chicago. Doctors will receive a blood test to determine their genetic profile, and then they'll use this information to guide treatment choices.

Based on ClinicalTrials.gov records.
