Stains / Test Description
The protein CA125 reacts with most epithelial ovarian neoplasms of endometrioid, clear cell and undifferentiated types. It is also used as a tumor marker for ovarian carcinomas; CA125 has also been described in other neoplasms such as seminal vesicle and anaplastic lymphomas. No reactivity has been shown for mucinous ovarian tumors. It reacts with both normal tissues and neoplasms of fallopian tube, endometrium, endocervix and mesothelioma.
