Why doesn t Clonazepam show up in a blood test report despite its consumption?

My 39 year old son is taking clonazepam 0.25 mg and his blood test show negative- not taking it. He does take one at am and one in the pm. I give it to him. It make me angry because it appears to the provider that I am not giving my son his medicine. What could be some reasons that it not showing up in his blood test? Thanks

It is due to the metabolites which are not detected in urine by standard tests.

My 17 year old daughter has gotten two long lasting ( over a week long) stomach flus this year. Once she starts vomiting, she doesn t seem to be able to stop. Her lab results all came back as normal, yet she is losing weight and still feels nauseous. She is not pregnant. She does not have an eating disorder. What about cyclical vomiting or some sort of allergy? Sugar definitely makes her feel worse
