What is CA 27-29 blood test?
CA 27-29 is a blood test used to monitor certain types of cancer. CA 27-29 is the name of an antigen, which is a substance that stimulates your body’s defense system. Certain types of cancer cells release CA 27-29 antigen into the blood. This test measures the levels of CA 27-29 in your blood.
What is normal tumor marker range?
Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
What does a high cancer antigen mean?
High levels of CA 19-9 are often a sign of pancreatic cancer. But sometimes, high levels can indicate other types of cancer or certain noncancerous disorders, including cirrhosis and gallstones. Because high levels of CA 19-9 can mean different things, the test is not used by itself to screen for or diagnose cancer.
What is a normal ca15 3 level?
Cancer antigen 15-3 (CA 15-3) is used to monitor response to breast cancer treatment and disease recurrence. The reference range of serum CA 15-3 is less than 30 U/mL. The upper limit of the range varies depending on the laboratory and kit used for the test.
Do high tumor markers always mean cancer?
Tumor marker tests can provide a lot of helpful information, but they aren’t fail-safe. Just because a person has tumor markers, it doesn’t always mean cancer is present or has come back. Conditions besides cancer can raise tumor marker levels.
What does a high CA 27/29 mean?
Generally, the higher the CA 27-29 level, the more advanced the breast cancer or larger the tumor burden. If the tumor produces CA 27-29, then tumor marker levels tend to increase as the tumor grows. The highest levels may be seen in metastatic breast cancer, particularly with metastases to the liver or the bones.
