Maybe: Vyvanse (lisdexamfetamine) is in the amphetamine family. Whether it will show up depends on the type of test and how often you use it. Urine "immunoassay " tests look for specific drugs. The tests is positively if drug is detected above a certain level, not just "positive". Vyvanse (lisdexamfetamine) is turned into amphetamine in the body and takes about 100 hours to clear from the blood and probably 2 more days to clear the kidney
