Serum level of iron and transferrin in normal and anaemic pregnant women.

Serum levels of iron and transferrin, and percent saturation of total iron binding capacity (TIBC) and latent iron binding capacity were estimated in 89 women in their I, II and IIIrd trimester of pregnancy. Associated infective, metabolic or degenerative diseases were excluded after clinical examination. The women were divided into three groups of normal, mildly anaemic and severely anaemic. In the normal group serum iron levels were within normal range irrespective of period of gestation, whereas in the anaemic groups, these were lower. Serum transferrin levels were significantly low in II and III trimester of pregnancy of anaemic women. Percent saturation of TIBC was even lower than normal in Ist trimester of pregnancy in normal pregnancy (27.12%). However in mild anaemic there was significant fall and in severe anaemia, it was very low, leaving a vast latent iron binding capacity. The decrease of % saturation of TIBC even in normal pregnant women is indicative of inherent poor stores, which may be due to defective diet.
