What will perphenazine show up as in a urine test?

Perphenazine is an antipsychotic medication that may not be routinely tested for in standard urine drug screens. However, if specifically tested for, it could potentially show up as a phenothiazine, which is a class of drugs that includes several antipsychotics. False positives for other substances may also occur due to the drug's chemical structure. Always consult with a healthcare professional for specifics on drug testing.
