Test Code DICSCR DIC Panel

Specimen Type

Blood

Container

Two light blue top tubes (3.2% sodium citrate) and one lavender top tube

Preferred Volume

9.4 mL

Offsite Collection Instructions

  • All sodium citrate light blue top tubes require a ratio of 9 parts blood to 1 part anticoagulant (example: a 3.0 mL tube requires 2.7 mL blood added to 0.3 mL of anticoagulant).
  • Transportation temperature: room temperature
  • If transport time exceeds 4 hours, centrifuge Coagulation tests for 10 minutes at 1500 x g and send a minimum of 1 mL plasma frozen at -20oC.
  • Note: For clients who do not have access to dry ice do not freeze the specimen. Follow the centrifugation instructions or send the whole blood sample. It now becomes vital that the specimen arrives in the lab within twenty three hours of collection. 
  • Do not centrifuge lavender tube for Platelet Count. Do Not Freeze.

  ISTH DIAGNOSTIC SCORING SYSTEM FOR DIC
 Risk assessment: Does the patient have an underlying disorder known to be associated with overt DIC?
   • If yes, proceed
   • If not, do not use this algorithm
 Order global coagulation tests (Platelet Count, D-Dimer, PT, Fibrinogen)
 Score the test results:
   • Platelet Count (per uL): >100,000 = 0; 50,000-100,000 = 1; <50,000 = 2
   • Elevated D-Dimer (ug/mL FEU): <0.4 = 0, 0.4-4.0 = 2, >4.0 = 3
   • Prolongation (in seconds) of PT above upper limit of its normal reference range: <3.0 = 0, 3.0-6.0 = 1, >6.0 = 2
    • Fibrinogen level (mg/dL): >100 = 0, <100 = 1
 Calculate score:
   • If score 5 or greater, compatible with overt DIC:
     Repeat score daily
   • If score less than 5, suggestive (not affirmative) for non-overt DIC: Repeat next 1–2 days
