OK so I am prescribed Oxy's and there has been a very few times I took less than prescribed and was just wondering if I were to get tested (like a blood or urine test) Would my doc be able to say ok you only took 240mg opposed to taking 320mg? I am a cancer patient and I have a script for 80mg (ER) and 30mg (IR) and like I said sometimes I don't take what I am supposed to but there are sometimes I am in more pain so I take the few I have left over and was just curious if I got tested would they know that I took less or when you are tested does it just say I have Oxy in my system? If you need to know anything else just ask and I will answer as best as my ability Thank you for your help...
