Hi Shel, the CA-19 does not mean that much alone as other factors have to be measured in to the numbers. I believe it can also mean an infection. I agree with Pam that you just keep calling until they let you talk to the Doctor. So many Doctors offices seem to be that way lately. Example, I started with a new GI in November who told me to come back in February. When I tried to make an appointment I was told that there books were not that far in advance for appointments and that they would call me. Did you get a call from them? Me neither.
Just be aggressive! Best of luck.
