Test Overview
Automated Sensitive Immuno Turbidimetric Assay
The D-Dimer assay is intended for use as an aid in the diagnosis of venous thromboembolism (DVT) and pulmonary embolism (PE), and disseminated intravascular coagulation (DIC), and is indicative of reactive fibrinolysis, and the presence of a clot.
Please see http://www.pathology.med.umich.edu/handbook/Tables/DDIMER_INNOVANCE.pdf for additional information.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
High levels of lipids or turbid samples can lead to falsely elevated or decreased values. Patient samples may contain heterophilic antibodies (e.g. human anti-mouse antibodies (HAMA) and rheumatoid factors) that could react with immunoassays to give a falsely elevated or depressed result. This assay has been designed to minimize interference from heterophilic antibodies. Nevertheless, complete elimination from this interference cannot be guaranteed.

Specimen Requirements
Collect specimen in a blue top (citrate 3.2%) tube. Mix by inversion. Specimen should arrive at lab within 3 hours of collection; transport at room temperature. Alternatively, centrifuge, aliquot plasma into a polypropylene plastic vial, and freeze the specimen within 4 hours of collection. Transport frozen specimen on dry ice. Collection of the blood through lines that have been previously flushed with heparin should be avoided. If the blood must be drawn through a VAD (vascular access device), the line should be flushed with 5 mL of saline and the first 5 mL of blood or six dead space volumes of the VAD discarded.
