| diagnostic tests used to determine DIC: |
|
Definition
- Platelet count: Normal platelet count is 150,000-450,000 cells /mm3. This test measures the number of circulating platelets and checks to see whether the count has decreased. - Prothrombin time (PT): Normal PT value is 11.0-12.5 seconds. This test measures the adequacy of the extrinsic coagulation system to see whether PT has increased. - Activated partial thromboplastin time (a PTT): Normal value for a PTT is 23-35 seconds. The test measures the adequacy of the intrinsic coagulation system to see if there is any increase. - Fibrinogen count: Normal value for fibrinogen is 170-340 mg /dL. Fibrinogen is essential for clot formation and the test determines whether the count has decreased. - D dimer: Normal value for D dimer is 0-250 ng / nL. This test checks whether there is increased breakdown of fibrin. |
