Topic: CA 19-9 lab values
I have my CA 19-9 level checked at each lab visit. I know this is a tumor marker and is supposed to indicate the level of activity of the cancer. However, I have no frame of reference. Normal is under 35, but what is considred "high" or "medium-high" or "through the roof"? Mine have been hanging around 58-64 for the past 4 months.
Can anyone contribute to my understanding of this mysterious tumor marker? Thanks!
