Book CEA Test in Dehradun

The CEA test is a blood test that measures the level of Carcinoembryonic Antigen, a protein normally produced in very small amounts by the body. CEA is classified as a tumour marker, a substance whose levels rise significantly in the presence of certain cancers, particularly colorectal cancer. During foetal development, CEA is produced in large quantities, but production drops to very low levels after birth. In adults, abnormally elevated CEA levels in the blood signal that certain cancer cells may be producing it in excess. CEA is most strongly associated with colorectal cancer and is the most widely used tumour marker for monitoring treatment response and detecting recurrence in patients diagnosed with colon or rectal cancer. It is also elevated in cancers of the lung, breast, stomach, pancreas, ovary, and thyroid. In India, colorectal cancer incidence is rising steadily alongside changing dietary patterns and increasing rates of obesity, making CEA an increasingly important diagnostic and monitoring tool. It is critical to understand that CEA is not a screening test for cancer in the general population as it can be elevated in several non-cancerous conditions. Its greatest clinical value lies in post-diagnosis monitoring and recurrence detection. The test involves a simple blood draw completed in under five minutes.

Doctors prescribe a CEA test in the following situations: Monitoring treatment response in patients diagnosed with colorectal cancer undergoing surgery, chemotherapy, or radiation therapy, where a falling CEA confirms that treatment is effective and tumour burden is reducing. Detecting colorectal cancer recurrence after curative surgery, where a rising CEA during post-operative follow-up is often the earliest indicator of recurrence, frequently preceding symptoms or imaging findings by several months. Staging and pre-operative assessment in newly diagnosed colorectal cancer patients, where the baseline CEA level before surgery provides prognostic information and helps guide surgical and oncological planning. Monitoring other CEA-producing cancers including lung, breast, gastric, pancreatic, and ovarian cancers in patients already under oncological care, where serial CEA measurements track disease progression or response to therapy. Investigating a suspected recurrence or disease progression in cancer patients who develop new symptoms, abnormal imaging findings, or unexplained weight loss during follow-up. Evaluating patients with a strong family history of colorectal cancer or known hereditary colorectal cancer syndromes such as Lynch syndrome or familial adenomatous polyposis as part of a broader surveillance strategy alongside colonoscopy.

The CEA test measures the concentration of Carcinoembryonic Antigen in the blood, reported in nanograms per millilitre (ng/mL). Normal CEA Range in India The standard reference ranges used across most Indian diagnostic laboratories and oncology centres are as follows. For non-smokers, a CEA level below 3.0 ng/mL is considered normal. For smokers, the upper limit of normal is slightly higher at below 5.0 ng/mL, as smoking independently elevates CEA levels. Interpreting CEA Results A CEA level between 3.0 and 10.0 ng/mL represents a mild to moderate elevation. At this level, non-cancerous causes including liver disease, inflammatory bowel disease, pancreatitis, and smoking must be considered alongside malignancy before any conclusion is drawn. A CEA level above 10.0 ng/mL is considered significantly elevated and raises stronger concern for an underlying malignancy, particularly colorectal cancer, and warrants urgent further investigation including imaging and endoscopy. A CEA level above 20.0 ng/mL in a patient with known or suspected cancer is highly indicative of active or metastatic disease and requires immediate oncological evaluation. In monitored cancer patients, the trend of CEA over serial measurements is more clinically important than any single value. A consistently rising CEA during follow-up, even within the normal range, warrants investigation for recurrence.

No fasting is required for the CEA test. You can eat and drink normally before sample collection. Our team confirms preparation requirements at the time of booking. Inform your doctor and the phlebotomist if you are a smoker, as smoking independently raises CEA levels and a higher normal reference range applies to smokers. Ideally, avoid smoking for several hours before sample collection for the most representative baseline. Inform the phlebotomist about all medications, chemotherapy agents, and hormonal therapies you are currently taking, as these can influence CEA levels and must be disclosed for accurate interpretation. Avoid scheduling the CEA test during or immediately after an acute illness, active infection, or significant inflammatory condition, as transient CEA elevations can occur in these states and may complicate interpretation. Stay normally hydrated before sample collection.
