D-DIMER
Collect
One 2.7 mL blue top (3.2% citrate plasma).
Also acceptable: One 1.8 mL blue top tube (3.2% sodium citrate).
All blue tops collected for coagulation assays which do not have a blood culture collected first must have a discard tube collected prior to filling.Discard tube should be another blue top in which greater than 1 mL of blood is collected.
Pediatric Collection
0.5 mL platelet poor plasma.
Unacceptable Conditions
Clotted sample; tube fill volume less than 90% or greater than 110%; more than 8 hours since collection; specimen not properly identified; incorrect container; insufficient sample volume.
Storage/Transport Temperature
Internal: Deliver to lab immediately.
Offsite: Separate plasma from cells as soon as possible. Place plasma in an aliquot container and transport to lab frozen.
Stability (from collection to initiation)
Whole blood: Ambient, 8 hours.
Platelet-poor plasma aliquot: Ambient, 8 hours; Refrigerated, 8 hours; Frozen (-20 degrees C), 2 weeks; Frozen (-70 degrees C), 6 months.
Remarks
For diagnostic purposes, D-dimer levels less than 500 ng fibrinogen equivalent units (FEU) make the diagnosis of deep venous thrombosis (DVT) or pulmonary embolism (PE) unlikely.
Performed by
PCL Clinical Laboratory- Coagulation
Performed
Daily
Methodology
Immunoturbidimetric method.
Reported
Same day
Reference Interval
0-500 FEU
Interpretive Data
For diagnostic purposes, D Dimer levels less than 500 ng/mL Fibrinogen Equivalent Units (FEU) make the diagnosis of Deep Venous Thrombosis (DVT) or Pulmonary Embolism (PE) unlikely.
