The one or two hours before testing won't be a problem AS LONG AS the sample hasn't been left at room temps over 5 hours. Most will say 8 hours, but I like to give leadway for comfort. I would say as long as you get the temp right you shouldn't have any problem. Just for added comfort, my frozen sample was thawed and brought up to testing temps and was sent off to a lab for testing. I've done it twice this way with NO harmful effects and NO reprecussions. Good luck and keep us posted.

One other note....if you find time limited you can place frozen sample in hot water for thawing before setting on counter to get to room temp. Whatever you do, give yourself extra time to take all the steps by getting up a little earlier if needed. It will be worth it.
KNOTME66 Reviewed by KNOTME66 on . Quick Review on using real urine Ok this tuesday morn I'm suppose to take a DOT piss test. Since it's too late to get QF I'm using my little bro's piss. So tell if what I'm going to do is right, and let me know if it's wrong. First I'll try and get some from him today dunno if I can get it from him tommorow cause of school and work, after he pisss I'm freezing it for two days, then I just thaw it out in warm water, keep it warm at the right temp, then just use it right? Someone said they used the piss overnight and it Rating: 5
