Dear Cagney,
I would suggest that you have your CA 125 repeated several more times. It could be just the
normalNormal saline flush flux of lab tests. if there is a trend such as the CA 125 is starting go up (for instance 40 then 60 then 100 etc), I would suggest a laparoscopy to see if there is any thing else going on.
Other reasons for an elevation in CA 125 include inflammation such as: pneumonia, gladder inflammation, diverticulitis, liver disease.
Also certain herbal medications can raise the CA125 ( probably by their effect on the liver).
