D-dimer testing in pregnant patients: towards determining the next ‘level’ in the diagnosis of deep vein thrombosis "Unfortunately, the utility of D-dimer testing in pregnancy remains unclear, because most diagnostic studies have excluded pregnant women and because D-dimer levels are often elevated in pregnancy in the absence of DVT.
Currently available D-dimer assays vary in their accuracy and utility in diagnosing DVT. Quantitative enzyme-linked immunosorbent assay (ELISA)-based assays are highly sensitive and can reliably exclude DVT in patients with suspected DVT. However, the false-positive rates of these assays are also high, particularly in patients with alternative reasons for an elevated D-dimer level, such as pregnancy.
In one study, most asymptomatic pregnant women were found to have elevated D-dimer levels by a rapid ELISA after 16 weeks of gestation . In another study, only 22% of women in the second trimester and none in the third trimester had normal D-
dimer values as measured by a latex agglutination assay using standard "non-pregnant’ cut-points."
"Recent literature indicates that D-dimer levels in each of the three trimesters are
approximately 39% higher: 700, 1000, and 1400 ng/dL for each trimester (normal
cutoff 500 ng/dL). So, figure out what trimester your patient is in and use the
corresponding D-Dimer level for that trimester. "
