New Blood Test for Ovarian Cancer

New Blood Test for Ovarian Cancer

Lead author Gil Mor, M.D., is an associate professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale School of Medicine in New Haven, Conn.

Yale researchers developed and tested the new blood test.

It's based on four proteins: leptin, prolactin, osteopontin, and insulin-like growth factor-II. If the levels of two or more of these chemicals fall within a certain warning area, the test will predict the patient has cancer.

Researchers tested the screening process on 200 women. Some were already diagnosed with ovarian cancer, and some were healthy.

The test correctly indicated which women had cancer 95 percent of the time and correctly indicated which women did not have cancer 95 percent of the time.
