Reticulocytes in healthy pregnancy

High reticulocyte counts are commonly found during pregnancy in non-anaemic Greek and Italian women, whereas in Anglo-Saxon women counts rarely rise above 2-0%. In this study, the Greek and Italian groups had peak mean values of 2-9%, although it occurred some weeks earlier in the Italian group. The Anglo-Saxon group's peak mean value was only 1-5%. The differences between the Anglo-Saxon and other groups are statistically highly significant and should be recognized when assessing haematological profiles in apparently normal women.
