Will clonazepam show a positive drug screen on the DOT drug screen?

My girlfriend is prescribed a small dose of clonazepam for mild anxiety. 25 mg. She has to take a DOT drug screen. She doesn’t want to show her prescription because they want to do a mental health exam to pass her. My Question is will clonazepam show a positive drug screen on the DOT drug screen which i believe is a 5 panel. My friend said it doesnt show up but i would like to hear from a expert to eliminate any doubt in her mind
