Figure 1

Second-trimester amniotic fluid concentrations of complement split products C3a and Bb. (a) Median level of amniotic fluid C3a was significantly higher () in women who developed early-onset preeclampsia as compared with the normal term pregnant control group (318.7 ng/mL versus 254.5 ng/mL). (b) Median level of amniotic fluid factor Bb was also significantly higher () in preeclamptic women than in normal pregnant women (1127 ng/mL versus 749 ng/mL).
