What does elevated CA 19-9 mean?
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 considered a normal CA 19-9 level?
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. Not every pancreatic cancer will cause elevated levels of CA 19-9, and some non-cancerous conditions (like pancreatitis and jaundice) can cause high levels of CA 19-9.
Does CA 19-9 mean cancer?
CA 19-9 does not cause cancer; rather, it is shed by the tumor cells and can be detected by laboratory tests in blood and sometimes other body fluids. This test measures the level of CA19-9. Since CA 19-9 can be measured in blood, it is useful as a tumor marker to follow the course of the cancer.
Can CA 19-9 be elevated without cancer?
When no malignant disease is found, a short-term follow-up is usually recommended5,6. Although elevated CA 19-9 level in healthy individuals is widely accepted to be unrelated to malignant diseases, patients with elevated CA 19-9 often present to the hospital in the fear of cancer.
How reliable is CA 19-9?
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 (14).
What are CA 19-9 levels at death?
The cutoff values of CA19-9 used in previous studies were varied. Among them, a value of 37 U/mL was most frequently used. This cutoff value is also recommended as the upper limit of the normal range for CA19-9, which is elevated in 70% to 80% of pancreatic cancer patients.
How long does it take to get CA 19-9 results?
However, CA 19-9 may also be elevated with the presence of other cancers. Preparation: No fasting required. Stop biotin consumption at least 72 hours prior to the collection. Test Results: 1-2 days.
What level of CA 19-9 indicates cancer?
If your CA 19-9 is above 37 U/mL, you may have cancer of the pancreas, liver, gallbladder, lung, colon, or stomach.
What are the symptoms of stage 1 pancreatic cancer?
Signs and Symptoms of Pancreatic Cancer
- Jaundice and related symptoms. Jaundice is yellowing of the eyes and skin.

- Weight loss and poor appetite.
- Nausea and vomiting.
- Gallbladder or liver enlargement.
- Blood clots.

How fast does pancreatic cancer go from Stage 1 to Stage 4?
We estimate that the average T1-stage pancreatic cancer progresses to T4 stage in just over 1 year.
Who is a part year resident of California?
If you lived inside or outside of California during the tax year, you may be a part-year resident. As a part-year resident, you pay tax on: Nonresident. A nonresident is a person who is not a resident of California. Generally, nonresidents are: This only applies if you’re domiciled outside of California.
What do you need to know about CA 19-9?
What Is CA 19-9? Antigens are substances that cause the immune system to respond. Carbohydrate antigen (CA) 19-9 is a type of antigen released by pancreatic cancer cells. It can also be referred to as a tumor marker. The CA 19-9 Radioimmunoassay (RIA) is a blood test that measures the CA 19-9 level in the blood.
When does CA 19-9 rise during radiation therapy?
During radiation therapy, CA 19-9 levels might be raised as dying cancer cells release CA 19-9. For this reason, the test is not usually done while the patient receives radiation treatment.
