D-Dimer
Measuring D-dimer level in 12 mins

The presence of D-dimer in blood indicates that thrombin has been formed and fibrin generated from fibrinogen in vivo as a result of activation of the coagulation system. This test measures the level in the blood to help assess the thrombotic state.

INTENDED USE :

ichroma D-Dimer is a fluorescence Immunoassay (FIA) for the quantitative determination of D-Dimer in human whole blood/plasma. It is useful as an aid in management and monitoring of post therapeutic evaluation of thromboembolic disease patients.

For in vitro diagnostic use only.

PRINCIPLE :

The test uses a sandwich immunodetection method; the detector antibodies in buffer bind to antigens in the sample, forming antigen-antibody complexes, and migrate onto nitrocellulose matrix to be captured by the other immobilized-antibodies on test strip.

More antigens in the sample will form more antigen-antibody complexes which lead to stronger fluorescence signal by detector antibodies, which is processed by instrument for ichromaâ?¢ tests to show D-Dimer concentration in the sample.

D-Dimer Rapid Test Device is used for the qualitative detection of D-dimer in human whole blood and plasma; The test is used as an aid in the assessment and evaluation of patients with suspected disseminated intravascular coagulation (DIC), deep vein thrombosis (DVT), and pulmonary embolism (PE).

During blood coagulation process, fibrinogen is converted to fibrin by the activation of thrombin. The resulting fibrin monomers polymerise to form a soluble gel of non-cross-linked fibrin. This fibrin gel is then converted to cross-linked fibrin by thrombin activated Factor XIII to form an insoluble fibrin clot. Production of plasmin, the major clot-lysing enzyme, is triggered when a fibrin clot is formed. Although fibrinogen and fibrin are both cleaved by the fibrinolytic enzyme plasmin to yield degradation products, only degradation products from cross-linked fibrin contain D-dimer and are called cross-linked fibrin degradation products. Therefore, fibrin derivatives in human blood or plasma containing D-dimer are a specific marker of fibrinolysis.

The D-Dimer Rapid Test Device (Whole blood//Plasma) detects D-Dimer through visual interpretation of color development in the internal strip. Anti-D-Dimer antibodies are immobilized on the test region of the membrane, and anti-mouse antibodies immobilized on the control region. During testing, the specimen reacts with anti-D-Dimer antibodies conjugated to colored particles and precoated onto the sample pad of the strip. The mixture then migrates through the membrane by capillary action and interacts with reagents on the membrane. If there is sufficient D-Dimer in the specimen, a colored band will form at the test region of the membrane. The presence of this colored band indicates a positive result, while its absence indicates a negative result. The appearance of a colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.

The cardiac troponin i fast test kit (colloidal gold) is intended for use together with the fia8000 quantitative immunoassay analyzer (fia8000). The product employs colloidal gold immunochromatogrphy to determine ctni in human serum, plasma, or whole blood specimens. Two monoclonal antibodies are employed to identify ctni specifically, resulting in a purplish red streak appears on the test line. The color intensity of the test line increases in proportion to the concentrations of ctni.

Then insert test card into the fia8000 quantitative immunoassay analyzer, the concentration of ctni is measured quantitatively and displayed on the screen. The result can be transmitted to the lab or hospital information system.

The One Step Test for NT-proBNP (colloidal gold) is intended for use together with the FIA8000 Quantitative Immunoassay Analyzer (FIA8000). The product employs colloidal gold immunochromatogrphy to determine NT-proBNP in human serum, plasma, or whole blood specimens. One monoclonal antibody and one polyclonal antibody are employed to identify NT-proBNP specifically, resulting in a purplish red streak appears on the test line. The color intensity of the test line increases in proportion to the concentrations of NT-proBNP.

Then insert test card into the FIA8000 Quantitative Immunoassay Analyzer, the concentration of NT-proBNP is measured quantitatively and displayed on the screen. The result can be transmitted to the lab or hospital information system.

The One Step Test for PCT (colloidal gold) is intended for use together with the FIA8000 Quantitative Immunoassay Analyzer (FIA8000). The product employs colloidal gold immunochromatogrphy to determine PCT in human serum, plasma, or whole blood specimens. Two monoclonal antibodies are employed to identify PCT specifically, resulting in a purplish red streak appears on the test line. The color intensity of the test line increases in proportion to the concentrations of PCT.

Then insert test card into the FIA8000 Quantitative Immunoassay Analyzer, the concentration of PCT is measured quantitatively and displayed on the screen. The result can be transmitted to the lab or hospital information system.

The One Step Test for B2-MG (colloidal gold) is intended for use together with the FIA8000 Quantitative Immunoassay Analyzer (FIA8000). The product employs colloidal gold immunochromatogrphy to determine B2-MG in human serum, plasma, or whole blood specimens. Two monoclonal antibodies are employed to identify B2-MG specifically, resulting in a purplish red streak appears on the test line. The color intensity of the test line increases in proportion to the concentrations of B2-MG.

Then insert test card into the FIA8000 Quantitative Immunoassay Analyzer, the concentration of B2-MG is measured quantitatively and displayed on the screen. The result can be transmitted to the lab or hospital information system.
