The D-dimer laboratory test is used to detect the presence of D-dimer (a protein fragment that is produced when a blood clot dissolves in the body).
The principle of the D-dimer test is based on the fact that when blood clots are formed and then broken down through a process called fibrinolysis, they release D-dimer protein in the bloodstream.
D-dimer test procedure
Draw a blood sample from a vein, usually in the arm. Label the tubes with patient information.
Gently mix the blood sample to prevent clotting.
Centrifuge the blood sample to separate the serum or plasma from the cellular components.
Utilize an appropriate laboratory method for D-dimer detection, such as ELISA or latex agglutination.
Perform quality control procedures to ensure the accuracy and reliability of the test results.
Finally measure the absorbance to quantify the D-dimer levels in the sample.
Compare the results to established reference ranges.
D-dimer test high Means
A high D-dimer test typically indicates increased blood clot formation and breakdown, suggesting conditions like deep vein thrombosis (DVT), pulmonary embolism (PE), or disseminated intravascular coagulation (DIC).
d-dimer test normal range
The normal range for D-dimer levels is typically below 500-550 micrograms per liter (μg/L) or D-dimer units (DDU). Elevated levels may indicate conditions involving increased blood clot formation and fibrinolysis,
what causes elevated d-dimer blood test
Elevated D-dimer levels can be caused by various conditions such as blood clots (deep vein thrombosis, pulmonary embolism), inflammation, infection, trauma, surgery, and certain medical disorders.
what does the d-dimer test show
D-dimer test typically shows increased blood clot formation and breakdown. It happens in deep vein thrombosis, inflammation, infection, trauma.
There are 5 types of Immunoglobulin, which are unique in their functions. These ig or antibodies synthesize in the host as the result of antigens. IGA, IgM, IgA, IgD, and IgE are different kinds of antibodies. Each antibody has a different function and structure. All antibodies consist of light chains…
