Patients with the prothrombin mutation are treated similarly to those with other types of thrombophilia, with anticoagulation for at least three to six months. Continuing anticoagulation beyond three to six months depends on the circumstances surrounding thrombosis, for example, if the patient experiences a thromboembolic event that was ...
Hypoprothrombinemia can be the result of a genetic defect, may be acquired as the result of another disease process, or may be an adverse effect of medication.For example, 5-10% of patients with systemic lupus erythematosus exhibit acquired hypoprothrombinemia due to the presence of autoantibodies which bind to prothrombin and remove it from the bloodstream (lupus anticoagulant ...
Prothrombin G20210A is congenital. [21] Prothrombin G20210A is not usually accompanied by other factor mutations (i.e., the most common is factor V Leiden). The gene may be inherited heterozygous (1 pair), or much more rarely, homozygous (2 pairs), and is not related to gender or blood type. Homozygous mutations increase the risk of thrombosis ...
Hyperprothrombinemia is a state of high of prothrombin levels in the blood [1] which leads to hypercoagulability. An example of a genetic cause includes the mutation prothrombin G20210A . [ 2 ] Hyperprothrombinemia is a risk factor for venous thromboembolism .
For example, sickle-cell disease (caused by mutations of hemoglobin) is regarded as a mild prothrombotic state induced by impaired flow. [1] Similarly, myeloproliferative disorders , in which the bone marrow produces too many blood cells, predispose to thrombosis, particularly in polycythemia vera (excess red blood cells) and essential ...
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.

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] The PT or PTT will be normal (the mixing study shows correction).
