Please help me figure this out, ive been CLEAN for 51 days, and have taken 2 urine drug tests,....?

the first of the 2 came back NON HUMAN?... it wasnt, it was my URINE... so, i tried soooo hard to fight that, but they were convinced otherwise, so i let it go.
I get another slip to go take my drug test 3 days later..... Great... so i go and take it...
Now im informed that they think i went to buy a drink to cover something up, and who-ever is reading, i dont need any scolding or rude remarks,,,,, For when i say im CLEAN 51 days, I MEAN IT.!!!!
But the results say.... urine drugs, NOT TESTED.
See notes below...
and they say ... Urine sample has interfereing substances. Above drug screening not preformed???
So i ask for a copy of something that specifies WHAT is interfering??? Because I KNOW "NOTHNG" IS...
my group gives me no answers....
And i NEEEED these tests for court, as ive been workin so hard at winning this awful custody battle to have my kids come back home. And working REALLY hard at my sobriety for thats what Myself, and my children need. Me clean. And I AM and

feel so CHEATED with these false accusations.... ??? Im baffled. Cant SOMEONE answer me as to why im not getting any feedback when im the one suffering from thier mistakes??? I took the test, i need them, im CLEAN, and im being told they dont know whats interfering with my urine? Shouldnt they be able to find out ? Being a LAB and all???

51 days is wonderful.

First of all, blood tests are not an option. Drugs and there by-products do not float around in your blood stream usually after 24 hours. So, when someone tells me that they want a blood test, it is usually a cover.

Secondly, you could ask for a hair sample. Very expensive, but it may be worth your while if you are truly not using anything.

Thirdly, the lab is probably looking at your PH balance of your UA. If you are using any vitamins, herbs, or any medications it can throw off your PH (however not by much usually). Tell the lab if you are taking anything. Are you drinking enough water? Are you drinking too much water?

These are all things that can hurt the balance of your UA. If you are messing w/ the samples it's going to be really bad for you. If you are not, ask for a hair sample or talk to the lab.

I really wish you a lot of luck. I know that custody battles can be stressful and painful. Do right by yourself, and keep your chin up.

Congratulations on 51 days clean.

Is a blood test an option? Offer to take that.

I feel so sorry for you! You must have fought so hard against your craving, and you couldn't get a clean chit. But this result is not conclusive and you should get the benefit of doubt. Can't you get legal advice in this matter?
All the best!
