How do you get a CEA blood test?
In adults, an abnormal level of CEA may be a sign of cancer. Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
When should I order my CEA test?
A CEA test is most useful after a diagnosis of a type of cancer that’s known to produce CEA. Not all cancers produce CEA. Increased levels of CEA may be found in the following cancers: colorectal or colon cancer.
What does CEA mean on a blood test form?
A carcinoembryonic antigen (CEA) test is used to check how well treatment is working in certain types of cancer, particularly bowel cancer. Carcinoembryonic antigens are proteins produced by some types of cancer.
Why is CEA not used for screening?
CEA testing is not used for screening, which is looking for cancer in people who have no symptoms. It is also not used for cancer diagnosis because other, noncancerous conditions can cause CEA levels to increase and because not all cancers cause CEA levels to rise.
How long does it take to get CEA test results?
Results. Results are usually available in 1 to 3 days.
How much does a CEA test cost?

How reliable is a CEA blood test?
Sensitivity of CEA ranged from 17.4 % to 100 %, specificity ranged from 66.1 % to 98.4 %, positive predictive value ranged from 45.8 % to 95.2% and negative predictive value ranged from 74.5 % to 100 %.
Can diverticulitis cause raised CEA levels?
CEA levels are elevated in 70% of patients with chronic liver disease and 50% of patients with acute liver disease. Elevated levels are also frequently seen in other gastrointestinal diseases including peptic ulcer, pancreatitis, diverticulitis, and inflammatory bowel disease.
Can stress increase CEA levels?
Our findings clearly indicated that immobilization stress results in enhanced serum CEA level whether the stress is acute or chronic. Consistent with our finding, there are reports suggesting that stress can increase tumor growth and tumor marker expression [26, 27].
