Analysis of D-dimer in pregnancy is recommended not to be ignored.

D-dimer refers to the products of lysis of fibrin, which is part of the thrombus. The analysis allows you to find out whether there is a risk of accelerated formation of thrombi in a future mother or not. Before taking blood, it is advisable not to drink liquid and food for at least 12 hours.

  • The 1st trimester is 750 ng / ml.
  • The 2nd trimester is 1000 ng / ml.
  • 3rd trimester - no more than 1500 ng / ml.

Increase in D-dimer in pregnancy

An increase in the level indicates an increased risk of blood clots, and a number of diseases can precede this:

  • Presence of diabetes mellitus.
  • The presence of diseases of the urinary system.
  • Confirmation of preeclampsia.
  • Confirmation of infectious diseases.
  • Presence of liver diseases.
  • Early detachment of the placenta and threat of miscarriage.
