Should ca-125 be within normal range (<35) for a healthy person or should it be zero?

Should ca-125 be within normal range (<35) for a healthy person or should it be zero?

Ca 125: The "normal" ca125 was established for post-menopausal women at <35 (any value 0-35).

Ca125 result is 20 which is within normal range >35. What is the perfect range. Is a result of 20 indicative of endometriosis at all?

Neither: If you had an elevated ca-125 prior to surgery for ovarian cancer and the level is down to a normal person's, then we can hope you have a cure, and should the level rise again it will be early warning. By itself, a normal ca-125 rules out nothing. I'm glad you're taking a proactive approach to your health. Good luck. ...Read more
