What is CEA scan?
CEA-Scan® (Arcitumomab) is indicated, in conjunction with standard diagnostic evaluations (e.g., additional imaging evaluation), for detection of the presence, location and extent of recurrent and/or metastatic colorectal carcinoma involving the liver, extrahepatic abdomen and pelvis in patients with a histologically …
What is CEA in pathology?
A carcinoembryonic antigen (CEA) test is a blood test used to help diagnose and manage certain types of cancers. The CEA test is used especially for cancers of the large intestine and rectum. Your doctor can also use the test results to help determine if a cancer treatment is working.
What is normal CEA range?
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).
How do you read CEA results?
The normal range for CEA is 0 to 2.5 nanograms per milliliter of blood (ng/mL). If CEA levels remain elevated during treatment, your treatment may not have been as successful as hoped. Anything greater than 10 ng/mL suggests extensive disease, and levels greater than 20 ng/mL suggest the cancer may be spreading.
Why CEA test is done?
This test is done to monitor the response to treatment and then to check for the return of colon and other cancers such as medullary thyroid cancer and cancers of the rectum, lung, breast, liver, pancreas, stomach, and ovaries.
What is a good CEA level?
What is a bad CEA number?
A CEA value of greater than 8 ng/ml was highly suggestive of residual disease or recurrence, even when no clinical evidence was present. Approximately 90% of the patients dying from colorectal cancer showed an increase in CEA to greater than 8 ng/ml during the course of the disease.
What does a CEA level of 5 mean?
A normal result is less than 5 nanograms per milliliter. Results might vary between labs. A higher-than-normal CEA level that increases over time might signal that your cancer has grown or has come back after treatment. But high levels of CEA do not always mean you have cancer.
