what are the normal ranges for cea test
Anyway, the typical CEA range is < 3.0 ng/mL (that is < 30mg/DL). Some folks are naturally higher. Others are in that range. Sometimes certain cancers will elevate a patients CEA levels, othertimes or with other cancers, CEA will be normal. Sometimes other things elevate CEA. Typically, from what I've read, heard, and studied, most doctors would say CEA < 10ng/mL (< 100ug/DL) could be normal or caused by things like smoking, not really a cause for alarm, but screening might be in order to determine the cause.
