Significance of maternal plasma lead level in early pregnancy loss.

This study was undertaken to investigate the relation of plasma lead levels, and early pregnancy losses. The concentration of lead in the plasma was measured in 20 women with a history of pregnancy loss before the 20th gestational week, and the results were compared with 20 control patients with viable intrauterine pregnancy. The results showed a mean lead level of 18.8 microg/dL in the cases of pregnancy loss and 22.1 microg/dL in the control patients, thereby indicating that there is no significant relation between early pregnancy loss and maternal plasma lead levels.
