Question: What Does A CEA Blood Test Show?

What does a CEA blood test detect?

A carcinoembryonic antigen (CEA) test is a blood test used to help diagnose and manage certain types of cancers.

The CEA test is used especially for cancers of the large intestine and rectum.

Your doctor can also use the test results to help determine if a cancer treatment is working..

What does a high CEA level mean?

A high level of CEA can be a sign of certain types of cancers. These include cancers of the colon and rectum, prostate, ovary, lung, thyroid, or liver. High CEA levels may also be a sign of some noncancerous conditions, such as cirrhosis, noncancerous breast disease, and emphysema.

What is a normal CEA tumor marker?

The CEA is measured in the blood and the normal range is <2.5 ng/ml in an adult non-smoker and <5.0 ng/ml in a smoker. The most common cancers that elevate CEA are in the colon and rectum but it can be elevated with gastric, ovarian and other cancers.

Does CEA increase with age?

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.

How often should CEA test be done?

CEA test. This is a blood test that detects the levels of CEA protein. High levels of CEA may indicate that a cancer has spread to other parts of the body. CEA testing is recommended every three to six months for five years.

Can CEA levels go up and down?

Serum CEA levels have therefore been widely used for postoperative surveillance in patients with colorectal cancer [14, 15, 16]. However, serum CEA levels fluctuate over time even in the same individuals. In some patients, the serum CEA level becomes positive in the absence of recurrence.

Can diabetes cause CEA levels to rise?

Elevated CEA levels in patients with pancreatic cancer have been reported to be associated with onset of diabetes [28]. It has also been reported that patients with diabetes have elevated levels of tumor-related markers, such as CA 19-9, CA125, CA153, in previous studies [9, 18].

What is considered a high CA 19 9 level?

If your CA 19-9 is above 37 U/mL, you may have cancer of the pancreas, liver, gallbladder, lung, colon, or stomach.

How accurate 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 %.

What is the normal range for CEA blood levels?

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).

Can stress cause tumor markers to rise?

The study, which followed 96 patients with chronic lymphocytic leukemia (CLL), found that those who felt more stress and anxiety about about their condition also had a higher volume of cancer cells in their blood and higher blood levels of markers for advanced disease.

What test can be done instead of colonoscopy?

Colonoscopy is one method of screening for colorectal cancer. Other methods are also effective and available. Alternatives to colonoscopy include sigmoidoscopy, which is a less invasive form of colonoscopy, and noninvasive methods, such as stool sample testing.

What can cause a false positive CEA?

Elevated serum CEA is not highly specific for colon cancer recurrence, while various other gastrointestinal disorders such as pancreatitis, peptic ulcer disease, biliary tract abnormalities (benign or malignant) and liver disorders may contribute to increased serum CEA and false-positive results [2].

How long does it take to get CEA blood test results?

It may also be present in people with cancer of the pancreas, breast, ovary, or lung. Results are usually available in 1 to 3 days.

Can alcohol increase CEA levels?

The mean plasma carcinoembryonic antigen (CEA) level was found to be significantly increased in 66 patients with alcoholic liver disease (4.4μg/1) compared with the mean CEA level in 164 healthy blood donors (1.6μg/1, p < 0.001).
