MDS Testing: What to Expect

If signs and symptoms suggest you have MDS, your healthcare provider may require tests to look at your blood and bone marrow.

What Are Blood Tests?

  • Through blood tests an examination of the number of blood cells and the size and shape of the blood cells will be made
  • In a complete blood count (CBC), blood is taken from your arm. It is then examined under a microscope to see the number of red blood cells, white blood cells, and platelets that are in your blood
    • Blood cells from MDS patients may also have certain abnormalities in size, shape, or other features that can be seen under the microscope
  • Additional blood tests may be performed to check your liver and kidney function

What Is a Bone Marrow Biopsy?

  • A bone marrow biopsy is done by inserting a hollow needle into the hip or breast bone and taking a sample of bone marrow
  • This test examines a small piece of bone and marrow to determine the size, appearance, and type of cells that the marrow is making

What Are Cytogenetic Tests?

  • These tests examine chromosomes, which contain the genetic information used to create new cells
  • Changes in chromosomes may occur in patients with MDS
