CA19-9

Cancer antigen 19-9 refers to a tumor marker associated with pancreatic, gallbladder, colon, and stomach cancers and is also known as an associated gastrointestinal antigen.

Cancer antigen 19-9 has high sensitivity and specificity for pancreatic cancer. Detection of ca 199 marker is helpful for differential diagnosis, disease monitoring, and diagnosis of pancreatic cancer metastasis.

SEKBIO is now offering Mouse anti-human CA19-9 mAb and Humanized anti-human CA19-9 mAb. These antibodies are suitable for use in diagnostics, including ELISA, lateral flow, CLIA, etc. And our products are highly consistent with Roche kits and similar antibodies of CanAg.

CA19-9 Antigen

Cancer antigen 199 refers to a tumor marker associated with pancreatic cancer, gallbladder cancer, colon cancer, and gastric cancer, also known as a gastrointestinal tract-associated antigen. tumor marker ca199 has high sensitivity and specificity for pancreatic cancer, and its positive rate is between 85% and 95%, and it decreases with the improvement of the condition after surgery.

CA199 Test

The determination of CA19-9 is helpful for the differential diagnosis and condition monitoring of pancreatic cancer. When CA19-9 is less than 1000 U/ml, it has specific surgical significance. After tumor resection, the concentration of CA19-9 will decrease. If it rises again, it can indicate recurrence. The diagnosis of pancreatic cancer metastasis also has a high positive rate. Peripheral metastasis is almost always present when the serum CA19-9 level is higher than 10000 U/ml.
