CA19-9 can range into the thousands. My first test came back at 2,567 and after stents were placed, it was down to 546, and at present it ranges from 17-29. Lots of prayer. No surgery other than the stents placed to drain liver thru bile ducts. Also have not had any chemo and because of genetic issues will never be able to have radiation, so GOD is my great physician and He is in control.
With the count so low in the beginning, I'll bet they are saying the chemo is working, so good luck. Standing in the gap for you.
