Several variables factor into determining how long Valium remains in the boyd's system, including which kind drug test is being used. Valium (diazepam) can be detected for a shorter time with some tests, but can be "visible" for up to three months in other tests.

The timetable for detecting valium in the system is also dependent upon each individual's metabolism, body mass, age, hydration level, physical activity, health conditions and other factors, making it almost impossible to determine an exact time valium will show up on a drug test.

How long the medication has been taken, how frequently and how large a dosage can also come into play in how low it is detectable by various drug tests.
