CD8 CD4 coexpression

     I've got a little question for all of you.  I have been running blood 
     samples over the last few days to standardize a 3-color cd3/4/8 test 
     on our Profile.  Everything has been running very nicely but I ran 
     into an interesting sample:
     
     CD8+ cells coexpressing CD4 to nearly the same level as the CD4+ 
     cells.
     
     Is this normal. I've only been doing flow a couple of years and at low 
     volume but I thought this looked kind of odd.
     
     Any help appreciated.
