I appreciate the replies, better late than never.  Anyway since my last posting I took another test about a month later (at no cost) allowed one makeup test. Again I got an inconclusive.  Took the test again five months later and once again another inconclusive.  The polygrapher was a little upset with me and said this result affects her percentages and recommended I wait as long as possible before retaking.                                       
I took the test at the end of June and nobody (PO) has  said anything about it since.  One person that responded said time was added for inconclusive. I'm curious if that is a case by case thing.  And as far as my not being familiar with the polygraph, I wouldn't be here if I was.
  For what its worth I take wellbutrin-sr 150mg. and lexapro 20mg. 
   I'm not going to bother again until my next six month is up.   
  Thanks again for all the replies
