? about GC/MS results

[riotgrrrl]

My girlfriend had a dirty UA at the methadone clinic. She has not done ANYTHING in at least 6 months

except LSD. Well it came back positive for Benzo's. So we paid for the GC/MS. The results are in and

here is what it says::
Oxazepam detected below cutoff value at 264 NG/ML.Cut off value 300 NG/ML.

OK so the clinic is saying that means she failed. The counselor admitted it was the first GC/MS she has read.
Is she below the cut off or not. I think she is below the cut off but I have no experience reading these either. Any help is appreciated!! Thanks

Is it possible she has taken this benzo sometime recently? I find it hard to believe it's still showing up at any level after 6 months, regarless of what the cutoff is.

No there has been no benzos in years. We both dislike them. The last we used was heroin 6 months ago. This clinic gave

me a false positive for Crystal Meth 2 months ago. I fought it and won though. I just think the way it reads she is below

cut off values. After that we will figure out what is metabolizing into Oxazepam.
