A detailed clinical study of 151 women in the third trimester of pregnancy in Kathmandu, Nepal (altitude 1450 m), indicates a previously reported statistical approach via mass screening of a population without regard to potential haematologic abnormalities appears valid in establishing (a) the lower limit of a normal hemoglobin (Hb) level in pregnancy, (b) the approximate percent of the population which is anaemic, and (c) the distribution of anaemic values. The existing WHO criterion regarding low normal Hb levels in pregnancy was misleading when used to diagnose the most common cause of anaemia. It was found that a pregnant woman with a Hb of 9.0 g% could conceivably not be anaemic at this altitude.
