Do hospital do a urine drug test to support result in a hair drug test?
A hair test is the most accurate so i dont think they would try and verify it with a urine test
It would be hard to say what the policy is of the hospital that took the hair sample for drug testing, I think if you test positive for drugs with your hair, they won't bother on going to the expense of urine testing.
the hair test is the result. so no.
