CEA test is used to detect cancer in the body. It is also used as a marker for other diseases, such as leukemia, lymphoma, and multiple myeloma. The level of CEA increases when various types of cancer are present in your body, like breast cancer, prostate cancer, etc., but it doesn’t mean that you have caught this disease or any other type of serious illness.
The CEA Testing
The CEA blood test is a blood test that measures the levels of CEA, a protein found in cancer cells. The higher your CEA level, the more likely you are to have cancer. CEA levels are low in non-cancerous cells and high in cancerous ones.
If you have cancer or if it has spread to other parts of your body, having low levels of CEA indicates that something might be wrong with either your tumor or its surrounding tissue.
What is a High CEA Level?
A high CEA level is a sign of cancer. Cancer in the body can be found in many places, including the liver, gallbladder, and pancreas. The most common cancers are breast cancer and colon cancer.
The CEA Testing measures levels of this protein called carcinoembryonic antigen (CEA). This protein plays a role in identifying if your body has been exposed to certain types of cancer cells or not. A high CEA level indicates that you may have been exposed to these types over time, which could mean something wrong with your health now or even later down the road if left untreated.

CEA Test Normal Range
A CEA (carcinoembryonic antigen) test is a blood test that measures the level of CEA in the blood. CEA is a protein that is present in some types of cancer, particularly colorectal cancer. The normal range for CEA levels varies depending on the laboratory that performs the test, but generally, levels below 2.5 ng/mL are considered normal.
It is important to note that a high CEA level does not necessarily indicate the presence of cancer, as there are other conditions that can cause elevated CEA levels such as smokers, chronic lung disease, inflammatory bowel disease, and liver disease.
Therefore, a CEA test should never be used as a standalone diagnostic tool, but rather as a tool to monitor the progression of cancer treatment or recurrence of the disease. A positive CEA test is usually followed by other diagnostic tests such as imaging or biopsy to confirm the diagnosis.
What is a Low CEA Level?
The CEA Testing is not useful if the CEA level is low. If your CEA level is normal, then there is no need for a second test. However, if you have had a liver or kidney transplant and your blood results show that your creatinine clearance (the amount of creatinine filtered by each kidney in 24 hours) is less than 75 mL/min/1.73m2 (or 140 mL/min/m2), then it may be necessary to take another form of biopsy called a hepatic biopsy.

What are the Symptoms of a High CEA Level?
High CEA levels are a sign of cancer. Several types of cancer can cause high CEA levels, including:
- Colon/Rectal Cancer
- Breast Cancer
- Pancreatic Cancer (Chronic Pancreatitis)
What are the Symptoms of a Low CEA Level?
A blood test can diagnose a low CEA level. If the diagnosis is confirmed, it may be treated with radiation therapy or chemotherapy.
If your CEA is high, you may experience symptoms like fatigue and joint pain. You may also notice that these problems worsen after eating certain foods (such as beef) or during cold weather. Treatment options include medications such as prednisone (Deltasone), azathioprine (Imuran), and cyclophosphamide (Cytoxan).
How Is the CEA Testing Done?
A doctor does this test. It can be done at a lab, a hospital, or even a doctor’s office. The CEA test measures the level of CEA antigen in your blood or urine. The results of this test are used to determine if you have pancreatic cancer or not. If something is wrong with your pancreas, these results could help diagnose it early on, so treatment may be started sooner than later (if possible).
The Carcinoembryonic Antigen (CEA) test is a blood test that can help determine if you have cancer. It’s not a definitive test for cancer, but it can help to determine if you have cancer. The CEA test detects the presence of malignant cells in your body and determines whether they are malignant or benign. Your doctor may recommend this type of test if you have symptoms such as:
- Painful growths on your skin or inside your mouth or throat.
- Painful lumps under your collarbone (sternum).
- Bulging lymph nodes.
To request a CEA Test at your local lab, go to your local hospital (or another healthcare provider) and schedule an appointment. When you have an appointment scheduled, they will ask if you have any health concerns.
If so, mention the symptoms of cancer (tumors/lumps in the breasts or elsewhere). If the results are positive for cancer (as described above), then they will send off a urine sample to be tested against the National Cancer Institute’s “Carcinoembryonic Antigen (CEA) test,” which is available nationwide. If it turns out that there is no cancer present, then they’ll repeat the test 3-6 months later.
