  2. D-dimer - Wikipedia

    en.wikipedia.org/wiki/D-dimer

    D-dimer (or D dimer) is a dimer that is a fibrin degradation product (FDP), a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis. It is so named because it contains two D fragments of the fibrin protein joined by a cross-link , hence forming a protein dimer .

  3. Fibrin degradation product - Wikipedia

    en.wikipedia.org/wiki/Fibrin_degradation_product

    Principles of D-dimer testing. Fibrin degradation products (FDPs), also known as fibrin split products, are components of the blood produced by clot degeneration. [1] Clotting, also called coagulation, at the wound site produces a mass of fibrin threads called a net that remains in place until the cut is healed. As a cut heals, the clotting ...

    en.wikipedia.org/wiki/Activated_protein_C...

    The aPTT-based APC resistance test involves a modified aPTT test performed in the presence and absence of activated protein C (APC). [1] [5] The ratio of these aPTT values is calculated and is called the APC sensitivity ratio (APCsr) or simply APC ratio (APCr).

  6. Partial thromboplastin time - Wikipedia

    en.wikipedia.org/wiki/Partial_thromboplastin_time

    The partial thromboplastin time (PTT), also known as the activated partial thromboplastin time (aPTT or APTT), is a blood test that characterizes coagulation of the blood.A historical name for this measure is the Kaolin-cephalin clotting time (KCCT), [1] reflecting kaolin and cephalin as materials historically used in the test.

    en.wikipedia.org/wiki/Dilute_Russell's_viper...

    Russell's viper, Daboia russelii Dilute Russell's viper venom time (dRVVT) is a laboratory test often used for detection of lupus anticoagulant (LA). It is an assessment of the time for blood to clot in the presence of a diluted amount of venom from Russell's viper (Daboia russelii), a highly venomous snake native to the Indian subcontinent and named after the herpetologist Patrick Russell.

  8. Protein dimer - Wikipedia

    en.wikipedia.org/wiki/Protein_dimer

    In biochemistry, a protein dimer is a macromolecular complex or multimer formed by two protein monomers, or single proteins, which are usually non-covalently bound. Many macromolecules, such as proteins or nucleic acids, form dimers. The word dimer has roots meaning "two parts", di-+ -mer. A protein dimer is a type of protein quaternary structure.

  9. Erythrocyte fragility - Wikipedia

    en.wikipedia.org/wiki/Erythrocyte_fragility

    Erythrocyte fragility refers to the propensity of erythrocytes (red blood cells, RBC) to hemolyse (rupture) under stress. It can be thought of as the degree or proportion of hemolysis that occurs when a sample of red blood cells are subjected to stress (typically physical stress, and most commonly osmotic and/or mechanical stress).
