What causes and UNKNOWN result in the ETG test?

[Guest guest]

I have been undergoing ETG testing for 1 1/2 years in my custody battle. Over

this time, 4

" unknowns " came as a test result, along with " Unknown due to unknown

interference. " I have

not tampered with the samples, ingested anything to interfere with the test,

knowlingly, and

cannot figure this out.

After the first one came in, I requested observation during testing. People are

questioning

whether I have ingested something purposely to alter the test and I have not.

The lab has been contacted by several different professionals and the reply was

simply that

the samples had been tested several times and the tests could not be completed

due to

unknown interference.

The courts treat these as positive results " in the absence of information

otherwise. "

I just don't understand how to approach this anymore. I can't keep doing these

tests, feeling

like they are not reliable. But, I can't prove them otherwise, and the burden is

on me.

The lab fully admits that they cannot find alcohol, but their responsibility

ends there.

Has anyone else experienced this? I'm at my wit's end.

Is there some kind of additional test that can be done to the remaining samples

to isolate the

problem? Please let me know.
