What are lab values for DIC?

DIC Scoring Systems

Test Results Points
Platelet count (×103/μl)* 80-120 1
51-80 2
≤50 3
Fibrin degradation products (FDP; μg/ml)** 10-19 1

Which test is normal in DIC?

To diagnose DIC, your doctor may recommend blood tests to look at your blood cells and the clotting process. For these tests, a small amount of blood is drawn from a blood vessel, usually in your arm.

What does high DIC mean?

Disseminated intravascular coagulation (DIC) is a serious disorder in which the proteins that control blood clotting become overactive.

How is DIC score calculated?

The ISTH DIC score is calculated using platelet count (≥100,000 = 0; 50,000-99,999 = 1; <50,000 = 2), fibrinogen level (≥100 mg/dL = 0; <100 mg/dL = 1), prothrombin time prolongation above upper limit of normal (ULN) (<3 seconds = 0, 3-6 seconds = 1, >6 seconds = 2), and D-dimer (<2 times ULN = 0, 2-4 times ULN = 2, >4 …

How low are platelets in DIC?

Typically, moderate-to-severe thrombocytopenia is present in DIC. Thrombocytopenia is seen in as many as 98% of DIC patients, and the platelet count can dip below 50 × 109/L in 50%.

Is platelet count normal in DIC?

Early in the course of DIC, the platelet count may be in the normal range but is often decreased from baseline. Platelet counts are rarely less than 20,000/mcL. D-dimer and fibrin degradation product (FDP) levels are almost always markedly elevated.

Why is PT and PTT increased in DIC?

Both PT and aPTT seem prolonged in about 50% of DIC cases which is attributed to the consumption of coagulation factors but can also be prolonged in impaired synthesis of coagulation factors and in massive bleeding.

Is LDH elevated in DIC?

In the laboratory schistocytes are prominent in the blood smear and LDH levels usually more pronounced than in DIC, while most conventional coagulation markers are normal.

What is fibrinogen level in DIC?

However, because fibrinogen is an acute phase reactant, it can be elevated in patients with DIC associated with a chronic inflammatory disorder. A fibrinogen level of 300 mg/dl, while normal, may be lower than normal in a patient with a baseline high fibrinogen due to chronic inflammation.

Are PT and PTT normal in DIC?

PT is prolonged in 50–75% of patients with DIC, and in 25–50% it is normal or shortened [7]. Activated partial thromboplastin time (APTT) is prolonged in 50–60% of patients with DIC, but a normal or shortened APTT may also be seen [7].

What is DIC and how is it used?

The technique can also be used to determine kinematic quantities of discrete points, such as: rotations, velocities & accelerations. As the name implies, DIC works on the principle of correlation whereby a series of digitally acquired images are successively taken of a deforming object surface throughout a materials test.

What is the reference range and lower reference limit?

The lower reference limit would be the third number from the beginning (top) of the sorted list and the upper reference limit would be the third number from the (end) bottom. The reference range would be the central 95% of the data, which falls between the 3rd and 117th values.

What is the reference range of the data?

The reference range would be the central 95% of the data, which falls between the 3rd and 117th values. Outliers can have a substantial effect on the calculation of reference ranges by this method and should be removed.

When should a reference range be established locally?

Because of these differences, reference ranges should be established locally whenever a new test is introduced or an existing method is changed. NCCLS recommends testing at least 120 patient samples for establishment of a statistically significant reference interval.
