- 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.
D-dimer is below the norm during pregnancy
If the D-dimer is significantly lower than the norm for pregnant women, this already indicates a decrease in blood coagulability of the risk of bleeding incompatible with life. In such cases, hospitalization, consultation of the hematologist, and a course of coagulants are required. It is especially important to carry out the analysis for D-dimer immediately before childbirth, when the fact of blood loss is irrefutable and in case of complications it will be necessary to quickly help.
