Guided Bone Marrow Differentiation Index (or Cell Morphology Analysis)
This test examines the types and proportions of cells found in a sample of bone marrow, helping doctors assess blood cell production and detect abnormalities like infections, cancers, or genetic disorders.

Why This Test Matters in Diagnosis
Bone marrow is the body’s factory for making blood cells. This test looks at how well different types of blood cells (like red blood cells, white blood cells, and platelets) are developing. It can help diagnose conditions such as anemia, leukemia, or other blood-related diseases by checking for unusual cell counts or shapes.
What to Expect Before the Test
You’ll likely receive a local anesthetic at the injection site, and a small amount of bone marrow will be taken from your hip bone. The procedure is usually quick and may cause mild discomfort. Recovery is fast, and you can return to normal activities soon after.
How the Results Are Used
Your results will show the balance of different cell types in your bone marrow. High or low counts of certain cells may indicate problems with blood production or disease. Doctors use these findings alongside other tests to guide treatment plans.
Common Conditions This Test Helps Identify
This test is often used to diagnose or monitor conditions like leukemia, myelodysplastic syndromes, or inherited blood disorders. It can also help track how well treatments are working or check for signs of bone marrow damage from conditions like chemotherapy or radiation.
