Description
Why It’s Done:
A Peripheral Blood Smear is commonly used to:
• Diagnose blood disorders such as anemia, leukemia, lymphoma, and myelodysplastic syndromes.
• Evaluate abnormal findings from a complete blood count (CBC), such as low or high white/red blood cell counts or platelet counts.
• Identify infections like malaria or other parasitic diseases by visualizing the organism in blood.
• Detect abnormal cell shapes (e.g., sickle cells, schistocytes, spherocytes) to help diagnose specific types of anemia or other disorders.
• Monitor the effects of chemotherapy, bone marrow diseases, or certain medications on blood cells.
• Investigate unexplained symptoms such as fatigue, bruising, fever, or bleeding.
Preparation:
• No special preparation is required for the test.
• Fasting is not needed.
• A simple blood sample will be collected from a vein, typically from the arm.
• Inform your doctor of any ongoing medications, recent infections, or chronic illnesses that may affect blood cell counts or morphology.
