Abstract
The purpose of the study was to examine the cause of the increased serum ferritin post-partum observed previously. B-hemoglobin, B-leucocytes, S-ferritin, erythrocyte protoporphyrin and S-orosomucoid were dermined in the blood of 21 pregnant women in the 39th week of pregnancy, two to four days and six weeks after delivery. The S-ferritin was increased from 12.1 μg/1 at the 39th week of pregnancy to 30.1 μg/1 post-partum. The probable reason for this increment is an acute phase reaction since a rise in the concentration of S-orosomucoid and B-leucocytes were concurrently observed.
