What is the CEA blood test?

This test measures the amount of CEA in the blood, and sometimes in other body fluids. CEA is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body. A high level of CEA can be a sign of certain types of cancers.

What is high CEA level?

Elevated levels of CEA occur when the CEA is higher than 3 ng/mL. These levels are considered abnormal. People with many types of cancers can have levels that are higher than 3 ng/mL. If you have values that are that high, it doesn't mean you have cancer. Other reasons can cause levels higher than 3 ng/mL.

What is normal range of CEA blood test?

Normal Results The normal range is 0 to 2.5 ng/mL (0 to 2.5 µg/L). In smokers, slightly higher values may be considered normal (0 to 5 ng/mL, or 0 to 5 µg/L).

How accurate is a CEA blood test?

Sensitivity of CEA ranged from 17. %, 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. %.

How fast does CEA increase?

Two distinct patterns of CEA rise were observed: a 'fast' rise in which serum concentrations reached 100 microgram/l within 6 months of the first elevation and a 'slow' rise in which concentrations remained less than 75 microgram/l for at least 12 months.

What causes CEA levels to rise?

The most frequent cancer which causes an increased CEA is cancer of the colon and rectum. Benign conditions which can elevate CEA include smoking, infections, inflammatory bowel disease, pancreatitis, cirrhosis of the liver, and some benign tumors in the same organs in which an elevated CEA level indicates cancer.

What is a bad CEA level?

Compared to the median level of 26.8 ng/mL, patients with CEA levels of >69 ng/mL were at a significantly elevated risk for progression. In contrast, the progression risk appeared to be lower for patients with CEA levels lower than 26.8 ng/mL, but a significance level was not reached.

What causes a CEA to rise?

The most frequent cancer which causes an increased CEA is cancer of the colon and rectum. Benign conditions which can elevate CEA include smoking, infections, inflammatory bowel disease, pancreatitis, cirrhosis of the liver, and some benign tumors in the same organs in which an elevated CEA level indicates cancer.

Is CEA level 8 high?

A CEA value of greater than 8 ng/ml was highly suggestive of residual disease or recurrence, even when no clinical evidence was present. Approximately 90% of the patients dying from colorectal cancer showed an increase in CEA to greater than 8 ng/ml during the course of the disease.

How often should CEA test be done?

The National Comprehensive Cancer Network, for example, recommends that people who are treated for stage II or III colon or rectal cancer have CEA testing every 3 to 6 months for 2 years and then every 6 months for 3 additional years, plus CT scans every 6 to 12 months for 5 years.

Can stress raise 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].

Can inflammation increase CEA levels?

Background. Carcinoembryonic antigen (CEA), a serological marker of malignant tumors, demonstrates a modest increase under nonmalignant conditions such as aging and smoking. Also, recent study results suggested that serum CEA levels may be related to insulin resistance or low-grade inflammation.

Why does CEA go up and down?

Carcinoembryonic Antigen, also called CEA, is a protein that may be elevated in many colorectal cancer patients and is detected in the blood. CEA levels are expected to go down in patients who have had surgery to remove their tumor. An elevated CEA may indicate a recurrence of your cancer.
