He took another home test on Monday morning, first void of the day. It was negative. Very clear line, too. Thank goodness, because shortly after that, his work called to tell him that he should come in that morning for the drug test. He drank a couple glasses of water (not for dilution, just to be able to take the test), and now we're just waiting for the results. We're feeling pretty good about it, and the hospital even volunteered the information that they've had several false positives recently. So maybe there's some wiggle room if, by some odd chance, his test comes up positive.
