CBC measures the cells that make up blood and can help screen for disorders like infection, inflammation, anemia, cancer, and abnormal bleeding. A blood film examines the shape and number of blood cells under a microscope to diagnose blood disorders or other conditions, such as identifying abnormal cells or infections like malaria. Performing both tests provides the most complete picture of a patient's health and any blood-related medical issues.

8. Blood Smear
Blood film is a blood test used to look for abnormalities in blood cells
It provides information on the number and shape of the cells which
can help doctors diagnose certain blood disorders or other medical
conditions.

9. Significance
• Evaluation of anemia
• Evaluation of thrombocytopenia/thrombocytosis
• Identification of abnormal cells ( blasts/ abnormal promyelocytes/ atypical
lymphoid)
• .infections like malaria and microfilaria
• Inclusions like basophilic stippling, Howell-jolly bodies and Cabot ring
