Lab tests for stomach cancer

Lab tests for stomach cancer

  • Genomic tumor assessment: Genomic testing examines a tumor on a genetic level to find the DNA alterations that are driving the growth of cancer. By identifying the mutations that occur in a cancer cell's genome, we can better understand what caused the tumor and tailor treatment based on these findings. Learn more about genomic tumor assessment.
  • Tumor molecular profiling: If you have a solid tumor, we’ll try to get a sample of tissue during a biopsy or surgery. Then, we’ll test for the presence of a variety of enzymes, proteins and genes to identify which therapies are likely to be most effective. Learn more about tumor molecular profiling.
  • CBC test: Complete blood count (CBC) tests determine the numbers of the different types of cells in the blood. A CBC test can be particularly helpful in determining whether you have too few red blood cells, which causes anemia.
  • Tumor marker tests: These blood tests may be used in addition to other tests if you have already received a stomach cancer diagnosis and are being treated for the disease. Tumor marker tests check for substances in the blood that digestive cancers may produce, such as carcinoembryonic antigen (CEA) and CA-19. The tests help doctors monitor the effectiveness of treatment. A rise in tumor marker levels may signal progression of the disease or a recurrence.
  • Liver function tests: These blood tests may be done to assess the function of your liver, an organ to which stomach cancer can spread.
  • Nutrition panel: With this test, we evaluate patients for deficiency of nutrients, such as vitamin D and iron. The test helps us identify the nutrients patients need replaced or boosted to support their quality of life. Learn more about our Nutrition Therapy program.

What are lab tests?

To diagnose stomach cancer, your doctor may recommend a various lab tests. After the doctor collects a blood sample, it is then sent to a pathologist for further testing.
