What are common causes for false-positive CA-125 Serum levels?
The CA-125 is not intended to be a screening test and should never be sued as one. There may be a complete list of what may cause a false positive somewhere, but there is little need for such a list in a medical setting, as clinicians do not rely on lists. Any irritation in the abdomen can cause a positive result. It’s especially inaccurate in premenopausal women (accuracy rate of about 50%); endometriosis, early-stage pregnancy or even normal hormonal fluctuations can lead to elevated CA-125 levels. Therefore a complete list can be very long.
