Summary

Immediately after delivery, D-dimer levels significantly increase in all women, even in uncomplicated pregnancies. This rise reflects normal pregnancy-associated fibrinolysis and requires careful interpretation alongside other clinical data.

Area of Science:

  • Obstetrics and Gynecology
  • Hematology
  • Clinical Chemistry

Background:

  • D-dimer is a crucial biomarker for coagulation.
  • Pregnancy naturally elevates D-dimer levels, increasing progressively until term.

Purpose of the Study:

  • To establish the normal range of D-dimer levels immediately postpartum in uncomplicated pregnancies.
  • To quantify the immediate post-delivery increase in D-dimer.

Main Methods:

  • A cohort of 100 consecutive deliveries was studied.
  • A rapid immunoturbidimetric assay was used for D-dimer determination.

Main Results:

  • D-dimer levels showed a significant increase in all women post-delivery.
  • Postpartum D-dimer levels were 1 to over 10 times higher than the normal range.

Conclusions:

  • Elevated fibrinolysis is a normal physiological response to pregnancy and delivery.
  • Postpartum D-dimer levels should be interpreted cautiously, considering clinical context and other diagnostic methods for suspected conditions like PE, DVT, or DIC.
