It just dawned on me. Are you maybe reading those lab ranges online versus on the report that shows your level of 4.6? That could explain the discrepancy. But that aside - this test is not generally useful.
I would be concerned that she is telling you that since it is well within range. What prompted you to have your CA-125 level drawn? It is not even accurate at diagnosing ovarian cancer as an elevated level can be caused by other things. A friend of mine had a CA-125 over 1000 when she had a benign (non-cancerous) ovarian cyst. She was over-treated (de-sexed) when all that should have been done was monitoring of the cyst or removal of JUST the cyst. The same thing happened to me except my CA-125 was not elevated.
