  2. Hypercoagulability in pregnancy - Wikipedia

    en.wikipedia.org/.../Hypercoagulability_in_pregnancy

    Pregnancy-induced hypercoagulability is probably a physiologically adaptive mechanism to prevent post partum hemorrhage. [1] Pregnancy changes the plasma levels of many clotting factors, such as fibrinogen, which can rise up to three times its normal value. [2] Thrombin levels increase. [3] Protein S, an anticoagulant, decreases.

  3. Thrombin generation assay - Wikipedia

    en.wikipedia.org/wiki/Thrombin_generation_assay

    A thrombin generation assay (TGA) or thrombin generation test (TGT) is a global coagulation assay (GCA) and type of coagulation test which can be used to assess coagulation and thrombotic risk. [ 1 ] [ 2 ] [ 3 ] It is based on the potential of a plasma to generate thrombin over time, following activation of coagulation via addition of ...

  4. Clotting time - Wikipedia

    en.wikipedia.org/wiki/Clotting_time

    Clotting time is a general term for the time required for a sample of blood to form a clot, or, in medical terms, coagulate.The term "clotting time" is often used when referring to tests such as the prothrombin time (PT), activated partial thromboplastin time (aPTT or PTT), activated clotting time (ACT), thrombin time (TT), or Reptilase time.

  5. Mixing study - Wikipedia

    en.wikipedia.org/wiki/Mixing_study

    Fresh normal plasma has all the blood coagulation factors with normal levels. If the problem is a simple factor deficiency, mixing the patient plasma 1:1 with plasma that contains 100% of the normal factor level results in a level ≥50% in the mixture (say the patient has an activity of 0%; the average of 100% + 0% = 50%). [3]

  6. Activated protein C resistance test - Wikipedia

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

    The activated protein C resistance (APCR) test is a coagulation test used in the evaluation and diagnosis of activated protein C (APC) resistance, a form of hypercoagulability. [ 1 ] [ 2 ] Hereditary APC resistance is usually caused by the factor V Leiden mutation, whereas acquired APC resistance has been linked to antiphospholipid antibodies ...

  7. Coagulation testing - Wikipedia

    en.wikipedia.org/wiki/Coagulation_testing

    Blood clotting tests are the tests used for diagnostics of the hemostasis system. Coagulometer is the medical laboratory analyzer used for testing of the hemostasis system. Modern coagulometers realize different methods of activation and observation of development of blood clots in blood or in blood plasma. [citation needed]

  8. Coagulation activation marker - Wikipedia

    en.wikipedia.org/wiki/Coagulation_activation_marker

    [1] [3] They may also be useful in the assessment of hypercoagulability and venous thromboembolism risk. [4] [5] [6] Levels of coagulation activation markers are increased with pregnancy, [7] with estrogen-containing birth control pills, [8] with menopausal hormone therapy, [9] [6] and with high-dose parenteral estradiol therapy for prostate ...

    Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms.
