Hello from JustAnswer.
No, Norco will not show up on a urine drug test one week later and usually would not show up on a test 4 days later.
First, it is important to realize that the hydrocodone in Norco is not well detected by the standard opiate urine drug screen. The standard opiate urine drug screen is oriented towards morphine, and is very good at detecting drugs that are metabolized into morphine, such as heroin and codeine. However, the standard opiate urine drug screen is not good at detecting opiates that are not metabolized into morphine, such as the hydrocodone. There can be some cross-reactivity, particularly when the concentration of hydrocodone is higher, but the hydrocodone will frequently be missed by the standard opiate urine drug screen.
There is a urine drug screening test specifically for hydrocodone. Within the context of this test and the small likelihood of cross-reactivity, the usual period of detection is about 2-4 days. Most people are in the middle of this range, but a small percentage of people will be at the end of this range. So, it is possible that it may be detected 4 days after last use, although unlikely. But by one week after last use, the test typically would not detect the hydrocodone.
If I can provide any further information, please let me know.
