Thanks, Toast! What do you make of the random posts about people passing home tests then failing the real deal? I figure that there is always a reasonable explanation for those... (didn't use first void of the day, random fluctuations of metabolites, insanely faint lines that don't constitute real passes, etc.) but I just wanted to get your opinion.
Thats a pretty tall order at this point. I would have to go back, dig up and review each of those random posts and get all the facts in order to opine.

My test is a 10 panel at labcorp and I know they only reserve GC/MS for presumptive positives so I think I should be ok with all the home tests I've clearly passed at several different points during the day over the past week.
What is it about the GC/MS that worries you?
