We are now utilizing Pathway Genomics to better serve our surgery patients. Genetic testing is performed via a blood sample to determine individual metabolic profiles and drug metabolism. The Pain Medication DNA Insight tells us which narcotic and non-narcotic medications will work best in the post-operative period. The Cardiac DNA Insight tests for the genetic risk of a variety of health related cardiovascular conditions, including blood clotting risk, that help us determine the best post-operative treatment plans. This service is covered by Medicare.
