Comparative study of white cell count and differential leukocyte count in school children at Dead Sea level and at Amman.
White cell and differential counts were studied in school children living at Amman (group A), Dead Sea natives (group B), and residents of the Dead Sea area who originated from different areas (group C). A total of 159 subjects from group A, 146 from group B, and 38 from group C, were studied. Significant leukopenia was observed in group B, as compared with groups A and C (p less than 0.005). This was due to selective neutropenia in group B (p less than 0.005). Careful analysis revealed that this difference was genetic and not environmental. Living at 390 m below sea level does not affect the white cell or the differential count.
