Tests and diagnosis

By Mayo Clinic Staff

Tests and procedures used to diagnose non-Hodgkin's lymphoma include:

  • Physical examination. Your doctor may conduct a physical exam to determine the size and condition of your lymph nodes and to find out whether your liver and spleen are enlarged.
  • Blood and urine tests. Blood and urine tests may help rule out an infection or other disease.
  • Imaging tests. Your doctor may recommend imaging tests to look for tumors in your body. Imaging tests may include X-ray, computerized tomography (CT) scan, magnetic resonance imaging (MRI) or positron emission tomography (PET).
  • Removing a sample of lymph node tissue for testing. Your doctor may recommend a biopsy procedure to sample or remove a lymph node for testing. Analyzing lymph node tissue in a lab may reveal whether you have non-Hodgkin's lymphoma and, if so, which type.
  • Looking for cancer cells in your bone marrow. To find out whether the disease has spread, your doctor may request a biopsy of your bone marrow. This involves inserting a needle into your pelvic bone to obtain a sample of bone marrow.
