Detection of protein tumor markers

Most solid tumors are derived from epithelial cells. When tumor cells rapidly differentiate and increase in value, some cell types or components that do not appear in normal tissues appear in large quantities, such as keratin as a cell scaffold, which becomes a tumor marker. Tumor markers whose chemical nature belongs to proteins include 1 enzyme; 2 protein or peptide hormones; 3 other proteins not belonging to the former two. Blood samples were collected from 2 ml of fasting blood and stored at -20 ° C for testing. Biochip detector analysis results. The contents of AFP, CA199 and CEA were measured after ELISA. Basic Information Specialist classification: Oncology examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: In the morning, blood tests are taken on an empty stomach. Normal value The normal value is negative. Clinical significance Abnormal results: Carcinoembryonic antigens in serum are elevated in colorectal cancer, lung cancer, pancreatic cancer, gastric cancer and breast cancer, as well as some other tumors. Hepatocellular carcinoma, yolk sac and embryonic malignant tumors, and some extrahepatic tumors can be re-synthesized. In the fetal period, alpha-fetoprotein (AFP) increases the serum AFP concentration, so AFP is a carcinoembryonic protein and becomes a serological marker of the above tumor. Acid ferritin has a certain value in the auxiliary diagnosis of liver cancer, and hematopoietic tumor can also be used as a reference for tracking the disease and observing the curative effect. Other protein-based tumor markers have associated malignancies or benign tumors. People who need to be examined: Tumor patients are generally required to check. Precautions Contraindications before the test: serum test, usually in the morning fasting blood test, it is therefore appropriate to fasting. Requirements for inspection: pay attention to serum is not contaminated and promptly sent for inspection. Inspection process Blood samples were collected from 2 ml of fasting blood and stored at -20 ° C for testing. Biochip detector analysis results. The contents of AFP, CA199 and CEA were measured after ELISA. Not suitable for the crowd Inappropriate people: no special requirements. It is generally used as a basis for cancer treatment or for prevention of physical examination. Adverse reactions and risks No relevant information.
