What is a CEA test? A carcinoembryonic antigen (CEA) test measures a specific blood glycoprotein called CEA. It means a protein with a lot of sugars added to it by normal or cancerous cells. Scientists first discovered CEA in 1968 when they isolated extracts of liver metastasized by colorectal cancer and also from normal fetal digestive tract.

2021年11月15日 · A CEA test measures the level of carcinoembryonic antigen (CEA) in the blood or other body fluid. As a type of tumor marker, CEA is an indicator of whether cancer is growing and spreading or diminishing with treatment.

2024年12月11日 · CEA levels are proven to be of some value in cases where ascitic fluid cytology is inconclusive. Serum levels greater than 5 µg/L are suggestive of carcinoma. Higher values are common in cancers with peritoneal involvement, with a sensitivity of 51% and specificity of 97% for carcinomatosis (p <0.01).

2021年4月17日 · CEA is an antigen (small protein) that is found on the surface of colon, rectal, gastric and other types of cancer cells and high levels of CEA can be detected in the blood of some patients with cancer and the developing fetus. 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.

6 天之前 · One way they can do that is with a carcinoembryonic antigen test. It measures a protein called CEA in the blood. People with some types of cancers have higher than normal levels of this...

2022年10月29日 · Carcinoembryonic antigen (CEA) is a tumor marker found in the blood or in other bodily fluids that can be used to monitor treatment for certain cancers. This article explains what the CEA test is, when it can be helpful in cancer treatment, and how to interpret its results.

2024年4月30日 · The Carcinoembryonic Antigen (CEA) blood test is a diagnostic tool used to measure the level of CEA, a protein that can be elevated in certain types of cancer. This test is primarily associated with monitoring colorectal cancer but can also provide insights into other cancers and health conditions.

2021年3月6日 · Each laboratory must establish its own normal range for CEA (Carcinoembryonic Antigen) in a blood test. These ranges depend on the makeup of the local population, the technologies used and the accuracy of the measurement.

Carcinoembryonic antigen (CEA) is a significant biomarker widely utilized in oncology. This glycoprotein plays a crucial role in cell adhesion and functions as a marker in various cancers. Recognizing CEA levels can provide invaluable insights in the diagnostic process and treatment management of cancer.

2024年1月7日 · TLDR: CEA is a protein that may indicate certain types of cancer when levels are elevated. Annual CEA testing after 50 is recommended for adults to detect early signs of cancer. The normal range for CEA levels is below 3 ng/mL. Lifestyle changes in terms of diet and exercise may help lower high CEA levels. What Is CEA?
