Therapath provides every customer protective coolers and cold packs to properly send the sample (according to this article). If the sample arrives without using the cold pack or cooler, I would bet that Therapath doesn't accept it and notifies the sender. There is no indication from this article that Therapath is at fault here or goes ahead with testing of improperly sent samples....actually, it appears they are the ones that discovered this and are making it known...probably from receiving samples not properly chilled.
