What is carbohydrate antigen ca125 used to diagnose? What is the normal value of carbohydrate antigen ca125?

When some women go to the gynecology department for a physical examination, the doctor may recommend that they do a carbohydrate antigen CA125 test. However, most people are very unfamiliar with this substance and may not have heard of it at all. At this time, they will feel a little confused and don't know what the significance of doing this test is. So what is the carbohydrate antigen CA125?

1. What is carbohydrate antigen CA125 ? In simple terms, carbohydrate antigen CA125 is a common type of hormone in the human body. Women generally show signs of elevation during the first three months of pregnancy. The detection of this substance is widely used in gynecological diseases. In clinical practice, it is usually used as an ovarian cancer marker to help detect gynecological cancer diseases such as ovarian epithelial cancer, cervical cancer, uterine cancer, and endometrial cancer. It also has a certain positive detection rate for pancreatic cancer, lung cancer, and rectal cancer.

2. Normal value of carbohydrate antigen ca125 <br/>Under normal circumstances, the normal value of this substance in the serum of healthy people is less than 35 ku/L or 35 U/ml for men and less than 40 μg/L for women. If it is higher than this critical value, it means the result is positive. It may indicate the occurrence of some benign gynecological diseases.
3. Diagnostic significance of carbohydrate antigen CA125
1. Diagnosis of ovarian cancer: Changes in the content of carbohydrate antigen CA12 are often used to diagnose ovarian cancer. If the test finds that the content of this substance in the serum is significantly increased, a preliminary diagnosis can be made. After radiotherapy, chemotherapy and surgery, it can also be used for testing, and the content may decrease.

2. Detection of other non-ovarian malignant tumors: Detection of the content of carbohydrate antigen CA12 has certain diagnostic significance for various malignant tumor diseases such as breast cancer, pancreatic cancer and gastric cancer.
3. Detection of non-malignant tumors: When women suffer from endometriosis, pelvic inflammatory disease and ovarian cysts, or other people suffer from pancreatitis, hepatitis and cirrhosis, the content of carbohydrate antigen CA12 often increases to varying degrees, but the positive rate is generally low. However, it can be used as a basis for diagnosis.
