My husband took a random on Wednsday. It was overnighted to the MN Medtox lab. He immediately came home and took a home test. It was negative, albeit with a light line. BUT a line He had smoked two days before, and he told me his pee for the home test was a bit lighter than what sample he gave. He doesn't smoke all the time, just occasionally. Will the lab call if positive? When should we hear something? The lab does do testing everyday according to their website, and there is an option for Saturdays. Worried! Do you think he has any chance in hell? I can't believe he smoked that day....and to top it all off the random came up on his birthday!!!!!!!!! Thanks.
