Don't know if you're still looking for an answer to this, but basically cheaper urine tests (like the immunoassay) only test for the two most common metabolites of benzopdiazepines which are Nordiazepam and Oxazepam. Lorazepam's metabolite is molecularly dissimilar from these more common metabolites and therefore only shows up as positive in very high concentrations. If it had been a GC/MS test it would have easily been detected.

My son overdosed on 80 ativan and his tox screen was normal when he got to the hospital. The hospital staff was totally confused

I am glad to find out the reason that my oxy and adderall show up every time but not my ativan and I take 2 mg q HS for over 10 years. Was driving me crazy. I have to take it or I don't sleep. Some doctor, I do not like anyway, accused me of selling it or whatever. I was an RN for 20 years but am not now. Her disrespect and accusation really ***** me off. So glad for an explanation.

What was the reason? My son takes his religiously, but the drug test was negative! How is this possible? He is on suboxone as well. This does show up. His Dr is alluding to the fact he's selling or not taking them! Do you know what could cause this to happen? Thank you.

The doctor is using a cheap drug test that only test for the more commonly abused benzos so it would only show positive if it was being taken at a much higher dose over a longer period. If you were to send it to a good lab it would show positive. Most labs don't go through the trouble to specifically check for Ativan.

I took 1mg if lorazepam 8 days ago. Would it show up in a urine test? Had not had any for at least 6 months.
