Are you on chemotherapy? Why is your WBC low?
If your white count is low you are more susceptible to infections. If you do have an infection of any sort your CA125 can be elevated.
Also, the comment by nyc lady is important to note; it is a rising trend that one should be concerned about. That said, I got upset when mine went from 2.9 to 5 so I know exactly what you mean.
Try not to worry (said the pot to the kettle !).
Peace.

It's not one test that should matter, should be a couple to establish a trend.
