Ca125 (Definition)

Ca125 is also known as Cancer antigen 125. Ca-125 (cancer antigen 125 or carbohydrate antigen 125) is a biomarker/tumor marker for ovarian cancer (etc); however, it is not sensitive or specific enough to use as a screening test. Also, a uk study showed that treating based on ca125 level did not improve outcomes. "125" comes from the 125th attempt to develop a marker. It was introduced by bast ...Read more

My ca 125 blood test result slightly elevated, with a different reading 3 times, what could cause this to happen?

CA 125: A ca 125 is not a very accurate test. Anything that affects the lining of your abdomen (peritoneum), lung cavity (pleura), or sac around your heart (pericardium) can change the ca 125 level. This includes everything from a cold to kidney failure to cancer. ...Read more

I went to take a ca-125 blood test and the doctors office said it was normal that I had a 8.6, is that actually normal?

I went to take a ca-125 blood test and the doctors office said it was normal that I had a 8.6, is that actually normal?

CA 125 - Why check?: 8.6 sounds like a normal value for the cancer antigen 125 (ca125) laboratory test. However, why did you want to get it? It is not a screening test for ovarian cancer. It is an adjunctive test for measuring tumor response (ie, a tumor marker) for patients with known ovarian cancer. It isn't perfect even when we know someone has ovarian cancer. ...Read more

Where do I get a ca-125 blood test if I have no insurance but worry about cancer?

Where do I get a ca-125 blood test if I have no insurance but worry about cancer?

It can be high even if you don't have cancer, and it can be normal in some situations when you do have cancer. My advice is to save your money, and visit your doctor if you have a specific concern. ...Read more

Why is the ca-125 blood test for ovarian cancer not part of a yearly checkup?

Why is the ca-125 blood test for ovarian cancer not part of a yearly checkup?

Not beneficial: The ca125 test is not used for screening for ovarian cancer because it does not work in the general female population. The ca125 can be abnormal in situations without any cancer and most importantly using this test does not save any lives like in the case of maamograms for breast cancer. ...Read more

I just received my blood test results which showed a ca-125 reading of 35. The blood test results showed hyper chromic microcytic anaemia.

I just received my blood test results which showed a ca-125 reading of 35. The blood test results showed hyper chromic microcytic anaemia.

Benign: A Ca 125 of 35 was found to be a useful cutoff point, with 99% of healthy women having values less than 35. Levels above 35 units are certainly seen in healthy women, but beyond the cutoff point of 35, the higher the value, the more likely there is trouble. With ovarian cancer, the levels measure in hundreds. Depends on what you are looking for. Repeat the test. You probably need some iron tabs. ...Read more
