[Estimation of iron reserves in the body of pregnant women].

The iron reserves were assessed using Cook's formulas in 86 women in following trimesters of pregnancy and in the course of labour. The range of obtained iron reserves' levels was wide and amounted from -570 mg to 874 mg. The iron reserves' levels differed statistically in the groups of women with normal iron amount, with hypoferraemia and with sideropenic anaemia diagnosed on the basis of haematologic and iron indexes. Iron reserves insufficient for the maintenance of iron positive balance in organism were found in about 30% of examined gravidae.
