What's this test for?
This test is ideal if you're experiencing unexplained abdominal discomfort, persistent digestive issues, or have a family history of pancreatic or gastrointestinal conditions. It helps monitor disease activity in people already diagnosed with certain gastrointestinal cancers like pancreatic, liver, gastric, or colorectal tumors, and can help predict relapse following treatment. Many people use this test as part of ongoing monitoring rather than initial screening, as it's most useful when tracked over time.
What's included in this test?
This test measures CA 19-9, a carbohydrate antigen that can be elevated in people with certain gastrointestinal cancers including pancreatic, liver, gastric, and colorectal tumors. It's primarily used for monitoring disease progression or treatment response rather than screening, helping doctors understand whether cancer activity is increasing, decreasing, or stable over time.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your CA 19-9 levels mean and how they relate to your digestive health or monitoring needs. These notes include personalized recommendations on whether you need follow-up testing, lifestyle considerations, or when to consult with an oncologist or gastroenterologist. You'll also get the standard lab report and can track your CA 19-9 levels over time using our trends feature, which is especially helpful for monitoring treatment response or disease activity.
Who should consider getting this test?
This test is most useful for people already diagnosed with gastrointestinal cancers who need to monitor disease activity or treatment effectiveness. It's also considered for individuals with unexplained persistent abdominal symptoms, significant digestive issues, or strong family history of pancreatic or gastrointestinal cancers. It's important to note that CA 19-9 should not be used as a general screening test in healthy individuals.
What symptoms indicate I may need this test?
Symptoms that might warrant this test include persistent unexplained abdominal pain, significant unexplained weight loss, yellowing of skin or eyes (jaundice), persistent digestive problems, or changes in stool patterns. However, this test is typically ordered by a doctor as part of cancer monitoring rather than for initial symptom investigation, so discuss any concerning symptoms with your healthcare provider first.
What does elevated CA 19-9 mean?
Elevated CA 19-9 levels can indicate active gastrointestinal cancer, particularly pancreatic, liver, gastric, or colorectal tumors. However, levels can also be elevated in non-cancerous conditions like pancreatitis, gallstones, liver disease, or even some benign digestive disorders. This is why CA 19-9 is best used for monitoring known cancers rather than diagnosis, and results should always be interpreted by your doctor in the context of your full medical history.
What is CA 19-9 and why does it matter?
CA 19-9 (Carbohydrate Antigen 19-9) is a protein found on the surface of certain cells that can be released into the bloodstream, especially when certain types of cancer are present. It matters because tracking CA 19-9 levels over time helps doctors monitor how well cancer treatment is working or detect if cancer is coming back after treatment. Rising levels may suggest disease progression, while falling levels often indicate successful treatment response.
How often should I retest my CA 19-9 levels?
If you're being monitored for gastrointestinal cancer or recovering from treatment, your doctor will typically order CA 19-9 testing every 1-3 months during active treatment or surveillance. The frequency depends on your specific diagnosis, treatment plan, and whether levels are stable or changing. Your oncologist will create a personalized monitoring schedule based on your individual situation and treatment response.
What happens if my CA 19-9 results are abnormal?
If your CA 19-9 is elevated, your doctor will evaluate the results along with imaging studies, other blood tests, and your symptoms to determine the cause. Rising levels in someone with known cancer may prompt treatment adjustments or additional scans, while elevated levels in someone without cancer diagnosis require further investigation. Your doctor may recommend follow-up testing, imaging studies like CT or MRI, or consultation with a gastroenterologist or oncologist.
Can CA 19-9 be elevated without cancer?
Yes, CA 19-9 can be elevated in non-cancerous conditions including pancreatitis, gallstones, cirrhosis, inflammatory bowel disease, and other digestive disorders. Some people also naturally produce little to no CA 19-9 due to genetic factors, making the test less useful for them. This is why CA 19-9 is not recommended as a screening test for cancer in healthy people and should be interpreted carefully by your healthcare provider alongside other clinical information.

What this means
Your CA 19-9 level is slightly above the normal reference range. While this is a mild elevation and not necessarily concerning on its own, it warrants monitoring and discussion with your healthcare provider, especially if you have gastrointestinal symptoms or a history of digestive conditions.
