It depends on what day of the week the biopsy was performed on plus Labor Day was a factor, not only that the labs only run Mon-Fri, not to mention mail time. Also keep in mind that the drs. staff cannot tell you a thing so if the dr is in surgery they'll tell you that it's not in yet. Try to get the number for the name and number for the lab, you'll find out they sent it out on Fri. ,then you call the dr back and it suddenly appears. That's what happened to us. You don't know who to believe.
