Cytochemical or Morphological Examination of Blood Cells (Bone Marrow Aspirate or Peripheral Blood Smear)

What This Test Measures

The test involves analyzing blood or bone marrow samples for cellular details, including red blood cells, white blood cells, and platelets. Technicians observe features like cell shape, size, color, and any abnormalities such as fragments, inclusions, or unusual cell counts.

This test is often used to diagnose or monitor conditions like leukemia, lymphoma, anemia, or infections. It may also be part of routine checks for people with known blood disorders or those undergoing treatments that affect blood cells.

A small blood sample is drawn, typically from your arm. The sample is then spread thinly on a microscope slide and stained to highlight different cell types. The slide is examined under a microscope by a trained pathologist or hematologist.

Results are usually available within a few days, depending on lab processing times. Your healthcare provider will discuss the findings with you, including any abnormal findings that may require further testing or treatment.

This test helps detect or monitor conditions such as blood cancers (like leukemia or myeloma), immune system disorders, genetic blood disorders (like sickle cell disease), and infections that affect blood cells.

The main risk is the mild discomfort from the needle used to draw blood. Bone marrow aspiration (if performed) may involve a slightly deeper needle insertion and could cause temporary bruising or soreness.

If you have a bleeding disorder or are on blood-thinning medication, let your healthcare provider know before the test to ensure safe sample collection.
