I have the same test with medtox (split sample) except mine's just a five panel. I go in a few hours but I'll be substituting. I've taken 3 at home tests now, failed the first one, but passed the last two over the weekend (one of which was a morning void, but the line was very faint).

I'm only 9 days clean but I'm 6 foot ~130 pounds with a very high metabolism. My test is in a few hours, should I even be substituting?

Still kinda nervous about it all. Thanks.
