Carbohydrate antigen 724 is high, and what is the normal value of carbohydrate antigen 724

Glycan antigen 72-4, also known as glycoprotein antigen 72-4 and cancer antigen 72-4, is a polymer glycoprotein carcinoembryonic antigen, glycoprotein antigen 72-4 is a marker of gastrointestinal tumors and ovarian cancer, and its specificity for diagnosing gastric cancer is better than that of glycoprotein antigen 19-9 and carcinoembryonic antigen. Carbohydrate antigen 724 is a tumor marker. It is mainly used for auxiliary diagnosis and prognosis evaluation of gastric cancer.

There is no specificity.

Hello, depending on what you said, this physical examination found that the carbohydrate antigen 724 is high, and it doesn't matter if the test results are only slightly higher, although it can be used as a reference index when diagnosing cancer, but sometimes healthy people may also test it a little higher.

If you say that the results of other aspects of the examination are normal and there are no symptoms of discomfort in the body, it does not matter, you usually have a reasonable lifestyle and eating habits, and do regular physical examinations.

The carbohydrate antigen (CA724) normal should be less than 5, and if it is significantly high, it may often be a problem with stomach cancer or other cancers of the digestive system.

Although carbohydrate antigen 724 can be used as a reference index for diagnosing cancer, it cannot be said that it must be caused by cancer.

Extended Materials. Clinical significance of CA72-4.

1.Gastrointestinal tumors: The serum Ca72-4 concentration in gastric cancer patients is increased, and the clinical sensitivity is about 40% to 60%, which is often used as the preferred tumor marker for gastric cancer, and is a good indicator for the detection of gastric cancer disease stage and efficacy.

3.For other malignant tumors: esophageal cancer, breast cancer, pancreatic cancer, bile duct cancer, cervical cancer and other diseases, serum CA72-4 can also be increased to varying degrees.

4.Benign diseases: a small number of diseases such as cirrhosis, pancreatitis, and pneumonia can also see elevated serum CA72-4 levels.

CA72-4 is a mucin-like high-molecular-weight glycoprotein recognized by CC49 and two monoclonal antibodies, with a molecular weight of 220-400 kd and a serum content of <6 U mL in normal human serum. The specificity of the detection of gastric cancer is high, with a cut-off value of 6 u ml. Benign gastropathy is only elevated <1% of patients, while the proportion of gastric cancer elevated can be reached, and the positive rate can reach 56% if tested at the same time as CA19-9.

Analysis: Excessive elevation of carbohydrate antigen CA724 generally suggests the possibility of a tumor, but it is not absolute.

Inflammation can also cause a transient increase in its value.

Guidance: It is recommended that patients should do relevant examinations according to clinical manifestations, such as chest and abdomen color ultrasound, etc., and if there are no abnormal findings, CA724 can be re-examined after 1-2 months, as long as there is no persistent elevation, there is no need to worry too much.

Carbohydrate antigen 724 normal value 6u ml.

In the 80s of the 20th century, experts used hybridoma technology to obtain a large molecule glycoprotein antigen (CA) that can recognize tumors, and developed a monoclonal antibody recognition system. CA is the associated antigen for tumor cells. Commonly used CA series are:

CA125 (ovarian cancer-associated antigen); CA19-9 (pancreatic and bowel cancer-associated antigens); CA15-3 (breast cancer-associated antigen).

CA72-4 is a mucin-like high-molecular-weight glycoprotein recognized by CC49 and two monoclonal antibodies, with a molecular weight of 220-400 kd and a serum content of <6 U mL in normal human serum. The specificity of the detection of gastric cancer is high, with a cut-off value of 6 u ml.

The normal value of carbohydrate antigen 72-4 is generally less than the normal reference range on the test sheet, and if it is outside this range, then the content of this substance is increased.

According to your description, carbohydrate antigen 724 is a marker for the detection of gastric cancer and various digestive tract tumors, and it is also a non-specific tumor marker. It is mainly seen in gastrointestinal tract, ovarian tumors, gastric cancer, ovarian mucinous cystadenoma and non-small cell lung cancer, and has a certain sensitivity to biliary system tumors, colorectal cancer, and pancreatic cancer

Hello, CA724 is mainly seen in digestive tract tumors, such as stomach, rectum, pancreatic bile ducts, etc., and can also be seen in tumors in other parts, such as ovarian tumors, non-small cell lung tumors, etc., with high sensitivity. It can also be seen in many patients with chronic gastrointestinal diseases, such as gastritis, acute pancreatitis, cholecystitis, etc. For women, blood draws before and after pregnancy or menstruation fluctuate depending on individual body differences.

Other groups of people will have high CA724 due to drinking, poor sleep, and eating supplements. If the examiner takes some hormone drugs or other drugs before the CA724 test, it may cause high CA724. Therefore, it is recommended to recheck every other week.

Carbohydrate antigen 724 is an experiment for tumor marker screening, and the results are more common in gastric cancer, so it is recommended that you have further examination and go to the hospital for a gastroscopy to clarify the condition and treat the symptoms**.

It's just that high is not clinically significant, these tests are a tumor marker, but the specificity is not high, and increased height does not mean that there must be a problem.

Carbohydrate antigen 724 (CA72-4).

1. Benign diseases: rheumatism, ovarian cysts.

2. Gastric cancer, mucinous ovarian cancer.

2. Serum CA72-4 is highly correlated with lymphatic metastasis of gastric cancer.

The degree of elevated serum CA72-4 level is associated with the stage of gastric cancer.

After the tumor tissue is completely removed, the serum CA72-4 level can rapidly drop to normal values and remain at normal levels. In approximately 70%** of cases, serum CA72-4 concentrations are elevated, prior to clinical diagnosis.

Serum, CA72-4 is persistently elevated, suggesting the presence of residual tumor.

Glycoprotein carcinoid-like antigen 72-4, also known as glycoprotein 72-4 and cancer antigen 72-4, is a polymer glycoprotein carcinoid-like antigen and glyco-stranded antigen 72-4 is a marker of gastrointestinal tumors and ovarian cancer, and its specificity for diagnosing gastric cancer is better than that of glycoprotein antigen 19-9 and carcinoembryonic antigen. Carbohydrate antigen 724 is a tumor marker. It is mainly used for auxiliary diagnosis and prognosis evaluation of gastric cancer.

There is no specificity.
