What is an abnormal CA 125 level?
Results of the CA 125 test are measured in units per milliliter (U/mL). The normal value is less than 46 U/mL. If your CA 125 level is higher than normal, you may have a benign condition, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer.
Does a high CA 125 always mean cancer?
The cancer antigen 125 (CA 125) blood test isn’t recommended for women with an average risk of ovarian cancer. While women with ovarian cancer often have an elevated level of CA 125 , an elevated CA 125 level doesn’t always mean you have ovarian cancer.
What cancer does CA125 detect?
Cancer antigen 125 (CA125) is a protein found on most ovarian cancer cells that is secreted into the blood stream and can be measured. CA125 can also be found on other normal and cancerous cells in the body.
What is CA125 normal range?
The normal range for CA 125 is 0 to 35 units/ml. While a CA 125 level over 35 may indicate cancer, it does not always mean the person has cancer. A CA 125 level over 35 is only a potential indicator.
How high can CA-125 levels go?
The normal range for CA 125 is 0 to 35 units/ml. While a CA 125 level over 35 may indicate cancer, it does not always mean the person has cancer….CA 125 Levels Chart.
| CA 125 Levels (units/mL) | Potential Cancer |
|---|---|
| >35 (high) | Possible cancer. More tests will be needed for a diagnosis. |
Can stress cause CA-125 to rise?
The most popular current theories suggest that CA 125 is synthesized by mesothelial cells in response to stress, which can be either mechanical stress caused by fluid overload, or inflammatory stress instigated by the release of mediators such as TNFα and interleukins [5,6].
What level of CA 125 indicates cancer?
While a CA 125 level over 35 may indicate cancer, it does not always mean the person has cancer. A CA 125 level over 35 is only a potential indicator….CA 125 Levels Chart.
| CA 125 Levels (units/mL) | Potential Cancer |
|---|---|
| 0 – 35 (normal) | Unlikely to have cancer. 99% of the time, it means no cancer. |
Can you still have cancer with a normal CA125?
A normal CA125 test cannot be used to rule out ovarian cancer. Some women with ovarian tumours never have an elevated CA125, and about half of women with early-stage tumours have a CA125 level in the normal range. So it’s possible to have ovarian cancer and a normal CA125 result.
How high can CA 125 levels go?
High levels of CA 125 (from 125 to 10.000 U/ml and higher) were revealed in 54 from 57 patients (94.7%) with malignant ovarian tumors.
