ovarian tumor markers

The ovarian tumor marker (CA125) is a glycoprotein present in the body cavity epithelium and Mullerian duct. When these organs develop lesions, serum CA125 is correspondingly elevated, especially the epithelial malignant ovarian tumor is significantly increased, so CA125 The corresponding antigen of epithelial malignant ovarian tumor is called. CA125 is of great significance in the early diagnosis of ovarian cancer. It is a tumor-associated antigen on the surface of ovarian tumor cells. It is present in the body cavity epithelial cells of embryonic development, disappears after birth, but reappears in the ovarian cancer cells and enters the systemic circulation. . Basic Information Specialist classification: Oncology examination classification: blood examination Applicable gender: whether women are fasting: fasting Tips: Stop taking the treatment of the tumor. Normal value The normal range is 0 to 35 (U/ML). Clinical significance Abnormal results: serum CA125 increased in the lesions, especially in the epithelial malignant ovarian tumors. At present, CA125 is mostly used for the diagnosis, differential diagnosis, treatment effect observation and prognosis judgment of malignant ovarian tumors. However, with the deepening of the research, it is found that the elevated serum CA125 is not unique to epithelial malignant ovarian tumors, in other tumors and some benign The disease can also rise to some extent. People who need to be examined: patients with benign tumors in the nest, patients with ovarian malignancies. Precautions Forbidden before the test: Stop taking the treatment of the tumor. Requirements for inspection: Pay attention to the cryopreservation of serum samples. Inspection process All serum samples were allowed to stand at room temperature for 2 hours after blood collection, then centrifuged at 1000 r/min for 5 minutes, and the serum was stored at -20 ° C until use. All serum samples were tested for SA, LSA, CA125, CP2 and 6B11Ab25 tumor markers, respectively. Not suitable for the crowd Inappropriate crowd: None. Adverse reactions and risks No relevant information.
