This test seems like another variation on the old CA-125 test. It appears rather cumbersome as you must first have the "baseline" work done and then be monitored regularly to see whether there are changes in the CA-125 levels. Sounds like numerous false positives and negatives are generated. Still, better than nothing but hardly earth shattering as it depends on the one primary marker and wouldn't seem likely to be useful in diagnosing someone with early stage cancer.
