ABSTRACT
Anaemia The lower limit of normal for haemoglobin concentration in the non-pregnant female is taken as 11.5-12 g/dL. In the pregnant patient, levels below 10.5 g/dL should be considered abnormal; although in certain situations such as multiple pregnancy associated with larger increases in plasma volume, the physiological dilution of haemoglobin may cause even lower concentrations of haemoglobin.
