My primary dotor wants me to take a urinary test i am on vyvance and seroqul is that the reason he is testing me? would weed show up on test results?

Drug Screening: Yes, illicit drugs will be on the test but most likely he will be testing you for stimulants and vyvanse (lisdexamfetamine) to make sure you are truly taking this medication.

Yes: Your doctor may be checking to see if you are taking your medication and also maybe making sure you are not taking substances that may be interfering with their action to help you.

What kind of test?: It's not clear from what you write whether this is a urine drug screen or a urinalysis, such as a primary care physician might order. If it's just a urinalysis, this checks your kidney function and whether there might be signs of infection in your urine, etc. If it's actually a urine drug screen, then this would indeed detect thc.
