Glycolipid tumor marker detection

Glycolipid tumor marker detection includes cancer antigen-50 (CA-50), cancer antigen 72-4 (CA72-4), cancer antigen 242 (CA242), and sugar chain antigen 19-9 (CA19-9). . The increase of CA-50 is seen in most malignant tumors. Dynamic observation of its level changes is valuable for the treatment of cancer, prognosis and recurrence. CA72-4 is a marker for ovarian tumors and gastrointestinal tumors. CA242 is a marker for pancreatic cancer and colon cancer. CA19-9 is significantly elevated in pancreatic, biliary, and gastrointestinal cancers. Basic Information Specialist classification: Oncology examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Generally, blood tests are taken, and it is advisable to have an empty stomach in the morning. Normal value The result was negative after the test. Clinical significance Abnormal results: serum 199 in patients with digestive system cancer increased significantly, such as pancreatic cancer, hepatobiliary cancer, gastric cancer and colorectal cancer can be 683, 535, 279 and 115 times of the normal mean, respectively, with pancreatic cancer as the highest, so CA199 was It is considered to be a good marker for pancreatic cancer. CA50 is closely related to CA199. It is often expressed simultaneously with glycosphingolipid antigen. The upper limit of serum CA50 is 14000U/L, and the positive rates for pancreatic cancer and hepatobiliary cancer are 85% and 80%, respectively. Compared with CA199, the colon The positive rate of cancer is 70% higher than that of CA199. People who need to be examined: Patients with glycolipid tumors can be examined. Precautions Taboo before the examination: generally blood test, should be fasting in the morning. Requirements for inspection: Pay attention to the serum is not contaminated, resulting in false positives. Inspection process Blood samples were collected from 2 ml of fasting blood and stored at -20 ° C for testing. Biochip detector analysis results. The content of CA199 and CA50 was detected after ELISA test. Not suitable for the crowd Inappropriate people: no special requirements. Adverse reactions and risks No relevant information.
