This may be the problem. Found this in a study and have seen it in several different sources.
The immunoassay often uses an antibody to
oxazepam, a metabolite of diazepam and chlordiazepoxide.6,7
This antibody has relatively low cross reactivity with
clonazepam and lorazepam and is therefore less likely to be
detected reliably.
This is a different lab, but this is what Aegis Labs says
"A patient taking alprazolam, clonazepam, flurazepam, or lorazepam will not test positive for benzodiazepine metabolites on an Aegis report."
