CA125 Cancer Monoclonal Antibody
CA125 is a protein normally made by certain cells in the body, including the ovaries, fallopian tubes, uterus, cervix, and lining of the chest and abdominal cavities (the pleura and peritoneum). When CA 125 is found in higher than normal amounts (more than 35 kU/ml), it is considered a marker for cancer. Benign conditions that can raise CA 125 include infections of the lining of the abdomen and chest, menstruation, pregnancy, endometriosis, and liver disease.
