Large D-Dimer Fluctuation in Normal Pregnancy: A Longitudinal Cohort Study of 4,117 Samples from 714 Healthy Danish Women

Figure 4

D-dimer concentrations as 5th, 25th, 50th, 75th, and 95th percentiles for each gestational week. D-dimer fluctuations for three randomly selected women are illustrated (square, triangle, and diamond). In spite of all having normal pregnancies, several women had stable high or low D-dimer values, while other had fluctuating D-dimer values throughout the pregnancy. Similar patterns are observed during delivery.
