Posted on Thu, 5 May 2016
Question: I have to take urine test in morning at 11 for 60 mg time release and want it to show up positive, what would be the best time to take it tonight to show up positive, Reason why is my heart was in AFib and was nervous in taking it tell they got it back normal by shocking it back again. And pain dr took me off because urine test was negative. I'm back working and on feet all day, and I'm in severe back and feet pain from accident years ago. I'm 68 years old and just very shock they took me off them because before knowing about heart I wasn't working and so I guess didn't realize I wasn't taking it like I should, so for 2 month it was negative. only have 1 pill left and I don't no what I will do with working without them. Even have a dr note explaining the one month. Sorry so long, but very surprised that they don't understand. Now if it was the other way around I would understand..If you could give me advise I really would appreciate it. Thank you. XXXXXXX p.s I would like to even show my dr tomorrow this email

Brief Answer:
mainly....get a better test.

Detailed Answer:
the time to peak blood levels varies but is in the 30 to 60 minute range with it coming out of the blood over the next 6 hrs and going into the urine. In theory about 6 hours would be best. AND that isn't the main issues:
1) how dilute the urine is YOU can change by at least 3 fold. Empty bladder completely before taking the pill. Then drink as little as possible.
2) the test sensitivity and what they call positive varies over a 10 fold range at least with the US army ignoring anything but huge levels and the dipstick being not very reliable.... ohhhhhhhhhhhh.......
3) the dipstick is set up to detect heroin. People THINK it detects oxycodone. It Does Not. you need the oxycodone specific test at as low a level of detection as they can get
