Q. My wife(53) has elevated CEA and CA19.9 levels - near 150, without any concomitant reason/observation? Comment
A. Hi Bobby3,
The most important question is why were these tests done?
An elevated level may result from many causes, some of them are simple and some are more problematic. IMHO the best thing would be consulting her doctor to consider the need to check-up her alimentary system.

Q. what is a safe tumor marker number range?
A. depends on the marker...most of the markers are materials that found normally in our body. and there are a number of markers and their levels differentiate. what marker do you mean?
