what do genesights tests even tell you

all i found out was that i am a cyp2d6 ultra rapid metabolizer . and the doctors couldn’t even agree on what that meant . one of them interpreted it as i can’t take things like codeine , because i will overdose on a normal dose. and the other doctor i went to told no it means that i need a higher than normal dose of drugs that are metabolized that way . so 👍 idek
