CA 15-3

The CA 19.9 quantitative test screens for abnormalities related to the pancreas and bile.

PSA is a protein made by your prostate, a gland in the male reproductive system. The test is used to screen for prostate cancer. Cancer screening means looking for signs of cancer before symptoms appear. But screening tests can’t diagnose cancer. If a screening test finds signs of cancer, you’ll need other tests to determine if you have cancer and how serious it may be.

Carcinoembryonic antigen (CEA) is a protein of the developing fetus. CEA levels gradually decrease or disappear after birth. In adults, abnormal CEA levels can indicate cancer. Smoking can also increase CEA. The test helps monitor treatment and checks for the recurrence of cancers of the colon, thyroid gland, rectum, lung, breast, liver, pancreas, stomach, and ovaries.

PSA is a protein made by the prostate, part of the male reproductive system. Most PSA in the blood is bound to serum proteins. A small amount is not protein-bound and is called free PSA. In men with prostate cancer, the ratio of free (unbound) PSA to total PSA is decreased. The lower the ratio, the greater the probability of prostate cancer.
