What level of CA 19-9 indicates cancer?
If your CA 19-9 is less than 37 U/mL, you may not have cancer. If your CA 19-9 is above 37 U/mL, you may have cancer of the pancreas, liver, gallbladder, lung, colon, or stomach.
Can CA 19-9 detect cancer?
High levels of CA 19-9 are often a sign of pancreatic cancer. But sometimes, high levels can indicate other types of cancer or certain noncancerous disorders, including cirrhosis and gallstones. Because high levels of CA 19-9 can mean different things, the test is not used by itself to screen for or diagnose cancer.
What is a normal cancer marker for pancreatic cancer?
CA 19-9: CA 19-9 is a tumor marker commonly associated with pancreatic cancer. The normal range of CA 19-9 is between 0 and 37 U/mL (units/milliliter), but people with pancreatic cancer often have higher levels.
How accurate is a CA 19-9 blood test?
Overall, an elevated serum CA 19-9 level has a sensitivity of 79–81% and a specificity of 82–90% for diagnosing pancreatic cancer in symptomatic patients.
What is considered a very high CA 19-9 level?
A CA19-9 level of >100 U/mL is more likely to indicate the presence of malignant diseases, especially early stage of pancreatic cancer (1).
Is pancreatic cancer treatable?
Despite the overall poor prognosis and the fact that the disease is mostly incurable, pancreatic cancer has the potential to be curable if caught very early. Up to 10 percent of patients who receive an early diagnosis become disease-free after treatment.
What is a good tumor marker number?
Normal range: < 2.5 ng/ml. Normal range may vary somewhat depending on the brand of assay used. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
What is CA 19-9 a marker for?
CA 19-9 is a type of tumor marker. Tumor markers are substances found in tissue, blood, or other body fluids that may be a sign of cancer or certain noncancerous conditions.
What is a high CA 19-9 level?
What Do the CA 19-9 Results Mean? The normal CA 19-9 range in a healthy person is 0-37 units per milliliter. CA 19-9 levels can be higher in patients with pancreatic cancer.
