Drug testing varies between companies. Most tests check for categories of drugs like Cannabis, Opiates, Cocaine, Amphetamines, Alcohol, Barbituates, etc. If your company tests for "Benzodiazepines" (which is what Klonopin is) then your test will be positive for Benzodiazepines. If you provide proof to your employer that a doctor prescribed it to you, you won't fail the test.
