Tests and diagnosis

By Mayo Clinic Staff

If abnormal numbers of blood cells have been detected in your blood, your doctor may begin with tests and procedures to rule out diseases and conditions other than myelodysplastic syndromes that have similar signs and symptoms.

In addition, your doctor may recommend tests and procedures used to diagnose myelodysplastic syndromes, such as:

  • Blood tests. Your doctor may recommend blood tests to count the number of blood cells in a sample of your blood (complete blood count) and examine your blood for unusual changes in the size, shape and appearance of various blood cells (peripheral blood smear).
  • Removing bone marrow for testing. During a bone marrow biopsy and aspiration, a doctor or nurse uses a thin needle to withdraw (aspirate) a small amount of liquid bone marrow, usually from a spot on the back of your hipbone. Then a small piece of bone and the enclosed marrow also is removed (biopsy). The samples are examined in a laboratory to look for abnormalities.
