Went in for the usual procedure, but this time the tester was a hospital toxicology lab, not Quest or Labcorps. Got a phone call from the lab asking me to call them back, no answer. But I'm thinking that the only reason they'd call me instead of the employer calling me is for a re-test. Subbed using Quick Fix Batch F11L-07 in a sealed 5.7 box (bought from ebay since the manufacturer doesn't sell to this state). Now I'm basically screwed and have to rely on dilution, so this job is probably out the window along with my reputation. Why would Spectrum Labs send out batches that are within a few months of expiration? Yeah, I know, I should've checked it out with adulteration strips, but thought the batch was within spec since it's not 2 years old (but I shouldn't have even gotten 2 year old stuff anyway).
