0.5 mL citrated plasma in non-additive transport tube.
Test Description
This test is used to measure the concentration of D‑dimers.
Interferences: Marked hemolysis and lipemia.
Note: Moderately to markedly lipemic samples can cause D-dimer results to be spuriously decreased. Citrated Whole Blood (Blue Top Tube) or citrated plasma is the only acceptable sample. The tube should be greater than 2/3rds filled. If submitting separated citrated plasma, label it as Citrated Plasma.
