Glycoantigens, also known as glycolipid tumor marker tests, include CA50, CA724, CA199, CA125, etc., which can be used for screening and prognostic testing for tumors and other diseases.
1.CA50: Normal human serum concentration <2.0 million U/L, its increase can be seen in pancreatic cancer, gallbladder cancer, primary liver cancer and other diseases, but need to pay attention to pancreatitis, cholangiopathy and so on, the index will also be elevated to different degrees.
2. CA724: This index is a marker for gastrointestinal and ovarian tumors. The serum concentration is 6.7μg/L in normal people, and its increase can be seen in ovarian cancer, colon cancer, etc. But it should be noted that it can be increased in normal people and benign gastrointestinal diseases.
3.CA199: this substance can also be found in salivary glands and prostate glands of normal people, and the serum concentration of normal people is <37,000 U/L. This indicator is the first choice of tumor marker for pancreatic cancer screening. Diseases such as gallbladder and bile duct cancers can also lead to its elevation. In addition non-tumor diseases such as acute pancreatitis, hepatitis and cholangitis can also cause an increase in this indicator.
4.CA125: Normal<35,000U/L, its elevation may be caused by cervical cancer, breast cancer, benign ovarian tumors, uterine fibroids and other diseases, and may also be caused by physiological factors such as pregnancy.
If the above indicators are abnormal, it is recommended to go to the hospital in time.
