ESR and iron status in pregnancy.

ABSTRACT

ESR (Westergen) correlated significantly with the iron status (as measured by Hb concentration, haematocrit, red cell count, MCH, P/H ratio, serum iron, TIBC and percent saturation of transferrin) in a group of pregnant women (PW) at term. Serum ferritin correlated negatively with the ESR but the correlation was not statistically significant. Serum ferritin levels of < 50 micrograms/L were present in 9 (34.6%) PW with ESR > or = 50 mm 1st hour and 5 (19.2%) PW with ESR < 50 mm 1st hour. The mean ESR in PW was 55.7 (+/- 22.9) and was > or = 50 mm 1st hour in 50% and < 75 mm 1st hour in 82.7%. The difference in the mean ESR in anaemic and nonanaemic PW was highly significant (p < 0.001), 87.5% anaemic PW with serum ferritin > 50 micrograms/L had ESR > or = 50 mm 1st hour, suggesting the possible effect of chronic infection in raising ferritin levels in these PW.
