Description
Ca 19.9 (G.I. Tract)
Sample Type:Serum
Tests Included:
Cancer Antigen 19-9 (CA 19-9) measurement
Sample Required:
Blood sample
Test Time:
Results are typically available within a few days.
Test Range Values:
Normal levels are usually below 37 units per milliliter (U/mL). Elevated levels might indicate certain gastrointestinal cancers or other conditions.
What is the test?
The CA 19-9 test measures the level of Cancer Antigen 19-9 in the blood, which can be elevated in some cases of gastrointestinal cancers, especially pancreatic cancer.
Test Procedure:
A blood sample is drawn from a vein, and the concentration of CA 19-9 is measured in the laboratory.
When to take the test:
The test is recommended for monitoring certain gastrointestinal cancers, assessing response to treatment, or detecting disease recurrence.
Who should take the test:
Patients with gastrointestinal cancers, especially pancreatic cancer, undergoing treatment, or being monitored might require this test. It’s usually ordered by oncologists or gastroenterologists.
Precautions for exceptional cases (pregnancy, etc.):
Pregnancy can cause elevated CA 19-9 levels. Pregnant individuals should inform their healthcare provider.
Frequently Asked Questions (FAQs) for Ca 19-9 (Gastrointestinal Tract) Test:
Q1: Can CA 19-9 levels be elevated in conditions other than gastrointestinal cancers?
A: Yes, elevated CA 19-9 levels can also occur in conditions like biliary obstruction, pancreatitis, or cirrhosis, not necessarily indicating cancer.
Q2: Is CA 19-9 used as a screening test for pancreatic cancer?
A: CA 19-9 isn’t recommended as a screening test due to its limitations in detecting early-stage pancreatic cancer.
Q3: Can lifestyle changes impact CA 19-9 levels?
A: Lifestyle changes typically do not significantly affect CA 19-9 levels. Regular check-ups and healthy practices contribute to overall health.
Q4: How frequently should CA 19-9 levels be monitored in cancer patients?
A: The frequency of testing is determined by the healthcare provider based on individual factors, treatment response, and disease status.
Q5: Can CA 19-9 levels help predict prognosis in cancer?
A: Elevated CA 19-9 levels might indicate disease progression or recurrence, but they aren’t used alone to predict prognosis.
