In brief: Blood and Urine Test

Percocet can be detected in the urine for 2-3 days; vyvanse (lisdexamfetamine) can be detected in the urine for up to a week; and, Ativan for three days in the urine.
Blood levels of all three are undetectable after 2-3 days under ordinary metabolism and an intact p450 enzyme system.

In brief: Deug testing.

If have legitimate prescriptions and reasons for taking these then you must be honest in providing this information to testing party.
Ativan (lorazepam) has long half life, but i suggest be honest if their use is legit.
