@mtstack normal is below 35. Mine at diagnosis was 1641. After 6 treatments was 81. It actually went from 1641 to 744 after 2nd treatment to 179 to 109 then the 81. That was one indicator the chemo was working. Just finished my 2nd second treatment of 2nd session and I'll probably have another CA125 test after 3rd treatment and also another scan.
