Findings from a blood smear evaluation are not always diagnostic in themselves and more often indicate the possibility or presence of an underlying condition, its severity, and the need for further diagnostic testing. but you can see them in the image below. PERIPHERAL BLOOD FILM - A REVIEW. The blood smear allows for the evaluation of these cells: These cell populations are produced and mainly mature in the bone marrow and are eventually released into the bloodstream as needed. Human Blood Smear 4. There are two major types of lymphocytes, B cell and T cell, but they cannot be distinguished when viewed under the microscope using standard staining techniques.

If you see them side by side in your drawing, the difference between them should become apparent. The parasite may be seen when a blood smear is examined under a microscope.
