Normal ranges for bone marrow differential cell counts in Saudi Arabians

The values for bone marrow nucleated cell differentials in normal Saudi Arabian donors of bone marrow have been determined by studying 18 such donors. Most of the figures obtained are similar to those in reference ranges published for normal subjects from Western countries although the percentages for segmented neutrophils, lymphocytes, and polychromatophilic normoblasts differ significantly. However, they provide a working reference range for assessing the bone marrow of Saudi patients with various types of haematological disease
