What are normal cancer antigen levels?
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 do cancer antigen numbers mean?
A cancer antigen number is also called a tumor marker. It is a number that indicates the amount of cancer antigen in the body. A cancer antigen is a protein made by cancer cells. Different types of cancer can make different types of antigens.
What is the normal range for cancer antigen 125?
Cancer antigen 125 (CA 125) is the only tumor marker recommended for clinical use in the diagnosis and management of ovarian cancer. The reference range of CA 125 is 0-35 units/mL (0-35 kU/L).
What is a cancer antigen 19 9 test?
What is a CA 19-9 blood test? This test measures the amount of a protein called CA 19-9 (cancer antigen 19-9) in the blood. CA 19-9 is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body.
How do you read cancer antigen 125 results?
How do I interpret my test results for certain types of ovarian cancer? The normal range of a CA 125 is less than 35. If your CA 125 is higher than 35, your doctor will consider your symptoms, the results from your scans (such as CT scan) if you had them done and your clinic examination.
What is a cancer antigen 15/3 test?
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.
Does a high CA-125 always mean cancer?
No, a high CA-125 does not always mean cancer is present. Generally speaking, the normal range of CA-125 is considered to be 0-35 units/mL, while a level above 35 units/mL is considered to be a high CA-125 level.
What is a high cancer antigen number?
An elevated level of CA 125 could prompt your provider to put you through unnecessary and possibly harmful tests. To check for cancer recurrence. Rising CA 125 levels may indicate that ovarian cancer has come back after treatment.
What does a cancer antigen test show?
Cancer antigen 19-9 (CA 19-9) is a protein found in the blood. When found at elevated levels, CA 19-9 may indicate the presence of certain types of cancers or noncancerous conditions.
What is cancer antigen 125 test?
Overview. A CA 125 test measures the amount of the protein CA 125 (cancer antigen 125) in the blood. This test may be used to monitor certain cancers during and after treatment. In some situations, the test may be used to look for early signs of ovarian cancer in people with a very high risk of the disease.
