USED QF AND THEY CANCELLED MY TEST AND NEED A RETEST. TRYING Q CARBO

Long story short I took a random DOT drug test on Monday at concentra using QF and they called me today and said it didn't pass svt testing and I need to retest . I'm assuming my next test will be observed so I did some research on q carbo and decided to buy a bottle and run a test . It surprisingly worked but only for about 3 hours, I went with the 16 oz ..I will use a 32 oz on Monday morning. Anyone been in my shoes and have advice ? I'm sitting bricks my whole career Is on the line , not just my job. This sucks !!
