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 does it mean when your tumor markers are high?
High tumor marker levels can be a sign of cancer. Along with other tests, tumor marker tests can help doctors diagnose specific types of cancer and plan treatment. Tumor marker tests are most commonly used to do the following: Learn if a person has cancer.
What is a high level of CA 19 9?
Here is what your results may mean: If your CA 19-9 is less than 37 U/mL, you may not have cancer. If your CA 19-9 is above 37 U/mL, you may have cancer of the pancreas, liver, gallbladder, lung, colon, or stomach.
What is considered a high tumor marker number?
Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
What is a CA 125 test?
This test measures the amount of a protein called CA-125 (cancer antigen 125) in the blood. CA-125 levels are high in many women with ovarian cancer. The ovaries are a pair of female reproductive glands that store ova (eggs) and make female hormones.
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 CEA be high without cancer?
Can CEA be high without having cancer? Yes, elevations in CEA and CA 19-9 levels may occur in patients without cancer.
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 .
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.
What does CEA mean in a blood test?
A carcinoembryonic antigen (CEA) test is used to check how well treatment is working in certain types of cancer, particularly colon cancer. Carcinoembryonic antigens are substances (usually proteins) that are produced by some types of cancer.
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 CEA levels fluctuate?
Serum CEA levels fluctuate over time in healthy individuals, and the intraindividual variation has been reported to be about 30% .
What happens if CEA is high?
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.
How do I lower my CEA levels?
Thus, we suggest that exercise for 2-3 days per week decreases the expression of CEA and improves body condition, without loading fatigue or stress, which may contribute to preventing cancer in the elderly women.
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.
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.
Can alcohol affect 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).
What is considered a high CEA level?
Levels of CEA higher than 20 ng/mL are considered very high. If you have CEA levels this high and you also have symptoms of cancer, it strongly suggests the cancer has not been removed successfully after treatment.
