Will thc show up on as regular urinalysis with culture for pre op appointment? i ate a pot brownie two days ago. never consumed marijuana before.

No: Routine urinalysis does not test for drugs. Such testing has to be specially ordered.

THC: THC will not show up on a routine urinalysis but you should be careful about the pasties you eat!

Urinalysis: A basic urinalysis tests for red and white blood cells, pH, concentration and other indicators of infection. A culture specifically is used to identify bacteria types and amounts in the urine. If a urine drug screen is performed, it will be positive.

No: A regular urinalysis would not reveal the presence of THC, a tox screen will.
