        Carcinoembryonic Antigen test, blood
      

This is one of the "oncofetal proteins" which may circulate in the blood of patients with colorectal adenocarcinoma.

Conditions Causing Elevations of this Marker:

  • cigarette smoking causes mild elevations
  • some colorectal cancers cause an elevation and, if the level goes to normal after surgery, it may be a worthwhile marker to follow for a recurrence of the cancer
  • hypothyroidism1

Situations Wherein the Level is Not Elevated:

  • even when extensive, some colorectal cancers fail to cause an elevation...it is useless to try to follow that type of case for a recurrence

Synonyms:

  • CEA
