This document discusses a human blood smear and its components. It mentions red blood cells, white blood cells including basophils and granulocytes, and provides images of blood smears at different magnifications. The smear shows the typical cellular components found in a healthy human blood sample.
The document describes the key parts and functions of a compound microscope used to examine peripheral blood smears. It outlines the proper procedure for making blood films, including using a spreader slide to create a thin, even smear. An ideal blood smear is translucent and uniformly thick. The process of fixing blood films with Leishman's stain and identifying features of a well-stained smear is also detailed. The major blood cell types—red blood cells, white blood cells including granulocytes and agranulocytes—are defined based on their appearance under different microscope magnifications.
Este documento presenta una introducción a la hematología, el estudio e investigación de las enfermedades hematológicas. Explica brevemente las funciones de los glóbulos rojos, glóbulos blancos y plaquetas, y los procesos de eritropoyesis, granulopoyesis y megacariocitosis que generan estas células sanguíneas. Finalmente, muestra un esquema del proceso general de la mielopoyesis hematopoyética.
Este documento presenta valores de referencia y descripciones morfológicas para varios componentes del hemograma, incluyendo hematíes, hemoglobina, hematocrito, VCM, HCM, CMHC y reticulocitos. Describe alteraciones en el tamaño, forma y contenido de los eritrocitos, así como condiciones como poliglobulia y anemia. Los valores de referencia se basan en fuentes como "La clínica y el laboratorio" de Prieto Valtueña y Balcells, y trabajos de Hurtado Monroy et al.
Peripheral blood smear examination plays an important role in the evaluation of various blood disorders. A good peripheral smear should be prepared using the wedge or coverslip technique to obtain an even distribution of red blood cells. The smear is then stained using the Romanowsky method which involves fixing the cells using methanol followed by staining with Giemsa stain. During examination, red blood cells, white blood cells, platelets and any abnormal cells or inclusions are evaluated under the microscope. Changes in the size, shape, color and structural features of red blood cells can provide clues to underlying hematological conditions.
