What is the normal value of carbohydrate antigen 199? It is normal in these ranges

The normal value of carbohydrate antigen 199 refers to the normal value of the tumor marker oligosaccharide tumor-associated antigen.

Normal value parameters of carbohydrate antigen 199: The normal value of carbohydrate antigen 199 (CA199) is less than or equal to 0-37kU/L, or less than 27.00u/ml; the serum carbohydrate antigen 199 concentration in a healthy human body is around 20u/ml.

The following points should be noted when measuring carbohydrate antigen 199 and judging abnormal values:

1. Carbohydrate antigen 199 is currently the most sensitive tumor marker for pancreatic cancer, but its increased value does not necessarily mean that you have cancer. According to clinical medical statistics, when the carbohydrate antigen 199 value exceeds the normal value by dozens or even hundreds of times, the chance of cancer is very high. The reference value is 1000u/ml.

2. Research and investigation have found that four types of cancer can cause the value of carbohydrate antigen 199 to increase by hundreds of times, such as pancreatic cancer: about 683 times, hepatobiliary system cancer: about 535 times, gastric cancer: about 279 times, and colorectal cancer: about 115 times.

3. The carbohydrate antigen 199 test does not require fasting; however, for people with severe hemolytic conditions, women during menstruation, patients with liver failure, renal failure, etc., the test values ​​will be extremely biased, so this test is not suitable.
