HE4 Blood Test

“HE4 is a novel serum biomarker that when combined with CA125™ significantly raises the level of sensitivity for the determination of risk of malignancy in patients presenting with a pelvic mass. HE4 is consistently expressed in patients with ovarian cancer, and it has demonstrated increased sensitivity and specificity over that of CA125 alone."
