What are the methods used for checking cea (carcinoembryonic antigen)?
A doctor has provided 1 answer
Immunoenzymatic test: A very commonly established way to check for the presence of certain proteins in the blood/serum uses a combination of monoclonal antibodies directed at one part of the CEA (carcinoembryonic antigen). One of the antibodies is linked to an enzyme which causes a chemiluminiscent reaction easily detected, the intensity of which corresponds to the amount of CEA detected.
