Serum ferritin and blood haemoglobin levels were studied in 229 women attending a family planning clinic. Ferritin values ranged from 2 to 438 Jlg/l and was skewed with an arithmetic mean of 41.8 and geometric mean of 23.4 flg/l; 26.6% were iron-deficient (ferritin < 12 Jlg/l). Haemoglobin values were normally distributed with a mean of 11. 7 g/dl but 59% were anaemic (Hb < 12 gjdl]. The correlation between ferritin and haemoglobin values was poor (r = 0.147) but almost all women with a haemoglobin below 10 g/dl were iron-deficient. This study reaffirms the need for monitoring iron-deficiency anaemia in apparently healthy women seeking contraception.
