Carcinoembryonic Antigen (CEA) is a protein found in the tissues of a developing newborn (fetus). The CEA test is used to evaluate cancer treatment. It serves as a primary indicator of the present tumor's size and aids in cancer staging. CEA testing is not used to screen for cancer in people with no symptoms. This test is also not used to diagnose cancer because non-cancerous illnesses can cause CEA levels, and not all tumors cause CEA levels to rise. CEA blood tests Qutub Vihar are available for breast, lung, thyroid, and pancreatic cancer. There is no need to fast for the CEA test Qutub Vihar. Its level rises in pancreatic, liver, stomach, breast, colorectal, and ovarian malignancies. Blood is usually collected from the veins for the test, and no prior preparations are necessary. The cost of a Carcinoembryonic Antigen test Qutub Vihar varies by region and facility.
A high level of CEA can indicate the presence of some forms of cancer. Cancers of the colon and rectum, prostate, ovary, lung, thyroid, and liver are examples
CEA's sensitivity ranged from 17.4% to 100%, its specificity from 66.1% to 98.4%, its positive predictive value from 45.8% to 95.2%, and its negative predictive value from 74.5% to 100%.
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
