Performing Laboratory

Methodology

Immunoturbidimetric Assay

Useful for diagnosis of the syndrome of intravascular coagulation and fibrinolysis, also known as disseminated intravascular coagulation; and it may also be useful in screening possible recent arterial thromboembolism, deep venous thrombosis, pulmonary embolism, or sickle cell.

Specimen Requirements

Specimen must arrive and be tested within 4 hours of draw.

 

Draw a full, light blue-top (3.2% sodium citrate) tube by “clean” venipuncture (no excessive trauma). Immediately after draw, invert tube several times to mix blood with additive. If there is a delay in shipment of >4 hours, immediately spin down for 15 minutes, and place 2 mL of citrate platelet-poor plasma in a plastic vial. (Clotted blood is not acceptable.) Send specimen frozen. Avoid hemolysis.
