What lab value indicates DIC?

Laboratory findings suggestive of DIC include a low platelet count, elevated D-dimer concentration, decreased fibrinogen concentration, and prolongation of clotting times such as prothrombin time (PT).

What is included in a DIC panel?

Panel includes Partial Thromboplastin Time (PTT), Prothrombin Time with INR (PT7), Fibrinogen (FIB), Advanced D-Dimer (ADV DIMER), and Platelet Count (PLT). A platelet count obtained within 24 hours of the DIC collection time may be used if no EDTA K2 specimen is submitted concurrently.

What is a DIC score?

Disseminated intravascular coagulation (DIC) is a hematological emergency reflective of life-threatening critical illness. The DIC score was developed as a consensus guideline by hematologists as part of the International Society of Thrombosis and Hemostasis (ISTH).

What tests confirm DIC?

In clinical practice, a diagnosis of DIC can often be made by a combination of the following tests :

• Platelet count.
• Global clotting times (aPTT and PT)
• One or two clotting factors and inhibitors (eg, antithrombin)
• Assay for D-dimer or FDPs.

How high is D-Dimer in DIC?

D-dimer is one of the criteria to diagnose (overt) DIC together with fibrinogen, aPTT and platelet count,10,11 and sharply elevated levels in particular strongly contribute to the diagnosis of DIC by consensus criteria. The optimal cut-off levels of D-dimer for diagnosing DIC vary between 3000 and 4000 µg/l.

What are the manifestations of DIC?

DIC may develop quickly over hours or days, or more slowly. Signs and symptoms may include bleeding, bruising, low blood pressure, shortness of breath, or confusion. Complications can be life-threatening and include bleeding or multiple organ failure.

Why is D-dimer high in DIC?

Fibrinolysis is an important component of DIC; thus, there will be evidence of fibrin breakdown, such as elevated levels D-dimer and FDPs. D-dimer elevation means that thrombin has proteolyzed fibrinogen to form fibrin that has been cross-linked by thrombin-activated factor XIIIa.

What is D-dimer normal range?

A normal D-dimer is considered less than 0.50. A positive D-dimer is 0.50 or greater. Since this is a screening test, a positive D-Dimer is a positive screen.

Do you give platelets for DIC?

In non-bleeding patients with DIC, prophylactic platelet transfusion is not given unless it is perceived that there is a high risk of bleeding. In bleeding patients with DIC and prolonged prothrombin time (PT) and activated partial thromboplastin time (aPTT), administration of fresh frozen plasma (FFP) may be useful.

What triggers DIC?

When you are injured, proteins in the blood that form blood clots travel to the injury site to help stop bleeding. If these proteins become abnormally active throughout the body, you could develop DIC. The underlying cause is usually due to inflammation, infection, or cancer.

When to use a laboratory test for DIC?

Laboratory testing for DIC is appropriate in patients with bleeding or microthrombi in combination with an associated DIC risk factor, including sepsis, obstetric disease, malignancy, and liver disease. The ISTH has developed a scoring system to aid in the diagnosis of overt DIC using laboratory testing results.

What does DIC stand for in medical terms?

Disseminated Intravascular Coagulation – DIC. Disseminated intravascular coagulation (DIC) is a disorder characterized by dysregulation of coagulation resulting in bleeding and coagulation, which without intervention may progress to organ failure and death. Laboratory findings suggestive of DIC consist of a low platelet count,…

What should the platelet count be for DIC?

Moderate to low thrombocytopenia (platelet count of 50-100 k/µL) is observed in the majority of patients with DIC, although severe thrombocytopenia (platelet count of <50 k/µL) may also occur. 3 Levi M. Diagnosis and treatment of disseminated intravascular coagulation.

What is the overt DIC score for hemostasis?

Criteria for Diagnosis. Score overt disseminated intravascular coagulation (DIC) based on the following system recommended by the International Society on Thrombosis and Hemostasis (ISTH) (Toh, 2007) Scores range from 0 to 8; a value of ≥5 is compatible with overt DIC ISTH Overt DIC Scoring System.
