Many possiblereasons: Oxycodone may not show up on a drug screen unless the screen is specifically geared to that drug. Ativan (lorazepam) should show up, but it depends on the dose. If you are on a low dose (0.5 mg a day) it may be negative. Also, if you are drinking large amounts of water, it dilutes your urine to where drugs may be below the detection limit of the test.
