Slothrop,
Jme, but if you give the lab the list of your meds and the contact info, you should not have any problem.
All they will verify is if you tested positive/negative for drugs...
Unless it's changed, there is no reason for your drug ingo to be passed on to them.

...but don't eat any poppy seed goodies before the test. I had two friends who tested positive after eating lemon poppy seed muffins..
my daughter sees a pain specialist and he will occasionally test his patients and has told them not to eat anything that contains poppy seeds.

Strange but true
