C-reactive protein in pregnancy and in the postpartum period.

Serum C-reactive protein levels were measured by means of the nephelometric immunoassay technique in 215 pregnant women at various gestational ages. The results indicate a positive correlation of serum C-reactive protein levels with gestational age. In addition, we studied serum C-reactive protein concentrations in 37 pregnant women in labor and during the postpartum period. Delivery was accomplished by either the vaginal or abdominal route and was associated with significant C-reactive protein production.
