What is innovance D-dimer?

Innovance® D-DIMER is a particle-enhanced, immuno- turbidimetric assay designed for use on coagulation ana- lyzers for the quantitative determination of cross-linked fibrin degradation products (D-Dimers) in human plasma.

What is D-dimer immunoassay?

Most commercial D-dimer enzyme immunoassays employ two antibodies, a fibrin specific capture monoclonal and a less specific antibody cross-reacting with epitopes present on fibrinogen.

How do you test D-dimer?

A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

What is D-dimer quantitative test for?

D-dimer tests are used to check for blood clotting problems. Blood clots can cause health problems, such as: Deep vein thrombosis (DVT) Pulmonary embolism (PE)

What is the normal range of D-dimer test?

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. [4][5][6][7] There is not necessarily a critical level for a D-dimer.

What is D-dimer normal range?

Is D-dimer elevated in Covid?

In normal conditions, the levels of D-dimer are low whereas high levels of D-dimer in your blood indicates presence of a major clot. Several studies suggest that levels of D-dimer may rise sharply in the case of COVID-19 and is associated with the severity of the disease.

IS 500 D-dimer normal?

D-dimer values < or =500 ng/mL fibrinogen-equivalent units (FEU) are normal. Within the reportable normal range (220-500 ng/mL FEU), measured values may reflect the activation state of the procoagulant and fibrinolytic systems, but the clinical utility of such quantitation is not established.

What is the innovance® D-dimer (k040882) assay?

The INNOVANCE® D-Dimer is substantially equivalent to the VIDAS® D-Dimer ExclusionTM (k040882) assay. The INNOVANCE® D-Dimer method, like the VIDAS® D- Dimer ExclusionTM method, is intended for use in conjunction with a clinical pretest probability (PTP) assessment model to exclude pulmonary embolism (PE) disease.

What is the innovance® D-Dimer® method?

The INNOVANCE® D-Dimer is substantially equivalent to the VIDAS® D-Dimer ExclusionTM (k040882) assay. The INNOVANCE® D-Dimer method, like the VIDAS® D- Dimer ExclusionTM method, is intended for use in conjunction with a clinical pretest probability (PTP) assessment model to exclude pulmonary embolism (PE) disease.

What is a positive D dimer test?

Patient specimens were tested with the INNOVANCE® D-Dimer assay and results were compared to a cutoff value of 0.5 mg/L (FEU). A D-dimer result <0.5 mg/L (FEU) was considered negative and a D-dimer result -0.5 mg/L (FEU) was considered positive.

Why are polystyrene particles aggregated when mixed with D-dimer?

Polystyrene particles covalently coated with a monoclonal antibody (8D3) are aggregated when mixed with samples containing D-dimer. The D-dimer cross- linkage region has a stereosymmetrical structure, i.e. the epitope for the monoclonal antibody occurs twice.
