i had this done. it told us that i have fewer serotonin receptors in my brain. also i am the MET/MET COMT type (there is val/val , val/met, and met/met) which shows us my predisposition to psychosis. it also told us that my liver takes a long time to metabolize medications taken orally. it told us that the best medication for my psychosis is risperdal/invega

and all they did was swab my mouth
