What level of CA 125 indicates cancer?
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. |
What is an abnormal CA 125 level?
If your CA 125 level is higher than expected, you may have a condition that isn’t cancerous, or the test result could mean that you have ovarian, endometrial, peritoneal or fallopian tube cancer. Your provider may recommend other tests and procedures to determine your diagnosis.
Is CA 125 only for ovarian 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 is CA 125 test normal range?
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).
Is CA125 a tumor marker?
Cancer antigen 125 (CA 125) is the only tumor marker recommended for clinical use in the diagnosis and management of ovarian cancer.
How accurate is CA125?
Results: Using a CA125 cutoff of 30 U/mL, an overall sensitivity of 94.8% (96.6% specificity) was obtained when comparing malignancies versus healthy postmenopausal controls, whereas a cutoff of 65 U/mL provided a sensitivity of 83.9% (99.6% specificity).
How high can CA 125 levels go?
In two from five patients with borderline tumors CA 125 concentration varied from 47 to 130 U/ml. 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.
What is the normal range of CA-125?
What does a high ca 125 level mean?
Many of them are looking at one biomarker in particular, CA-125. CA-125 (cancer antigen 125) is a protein produced on the surface of cells that then circulates in the blood. High amounts of CA-125 in the blood (generally more than 35 units per mL) could be a sign of ovarian cancer.
What causes elevated ca 125?
Buamah P. Benign conditions associated with raised serum CA-125 concentration. J Surg Oncol 2000; 75:264.
What does an elevated serum CA 125 test indicate?
The CA-125 is a blood test that is often, but not always, elevated with ovarian cancer. If a postmenopausal woman has a mass and an elevated CA-125, she has an extremely high risk of having a cancer. However, in younger women, CA-125 is extraordinarily inaccurate.
What will a CA125 test Tell Me?
The CA-125 test looks for certain proteins in your blood. Ovarian cancer can be the reason for these proteins, but other conditions can cause them to be in your blood as well. Your doctor may order a CA-125 test if you’re about to start treatment for ovarian cancer.
