Understanding medical tests for FL

FL cannot be diagnosed by symptoms alone. In fact, you are often not the first to notice your FL. It is usually detected by routine checkups, or blood work for other health issues. Your doctor will need to use medical tests to diagnose your FL. Medical tests will also tell where FL is in your body.

  • Routine tests such as physical exam, blood cell counts, and bone marrow biopsy
  • Flow cytometry—a sample of your cells is examined using a laser beam and a computer to find out the type of cancer and the number of cells involved
  • Imaging tests such as PET-CT or CT scans—these scans produce pictures of the inside of your body that help show where FL is
