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. [2]
The prothrombin time ratio is the ratio of a subject's measured prothrombin time (in seconds) to the normal laboratory reference PT. The PT ratio varies depending on the specific reagents used, and has been replaced by the INR. [3] Elevated INR may be useful as a rapid and inexpensive diagnostic of infection in people with COVID-19. [4]
Tests for thrombophilia include complete blood count (with examination of the blood film), prothrombin time, partial thromboplastin time, thrombodynamics test, thrombin time and reptilase time, lupus anticoagulant, anti-cardiolipin antibody, anti-β2 glycoprotein 1 antibody, activated protein C resistance, fibrinogen tests, factor V Leiden and ...

Prothrombin time > 100 seconds or Three of the following variables: Age < 10 yr or > 40 years; Cause: Hepatitis C or E; halothane hepatitis; idiosyncratic drug reaction; Duration of jaundice before ...
Cirrhosis can take quite a long time to develop, and symptoms may be slow to emerge. [13] Some early symptoms include tiredness, weakness, loss of appetite, weight loss, and nausea. [13] Early signs may also include redness on the palms known as palmar erythema. [11] People may also feel discomfort in the right upper abdomen around the liver. [13]
The syndrome is associated with changes on blood tests such as a high blood ammonia level, low blood sugar level, and prolonged prothrombin time. [2] Often, the liver is enlarged in those who have the syndrome. [2] Prevention is typically by avoiding the use of aspirin in children. [1]
The thrombin time (TT), also known as the thrombin clotting time (TCT), is a blood test that measures the time it takes for a clot to form in the plasma of a blood sample containing anticoagulant, after an excess of thrombin has been added. [1] It is used to diagnose blood coagulation disorders and to assess the effectiveness of fibrinolytic ...
Coagulopathy (also called a bleeding disorder) is a condition in which the blood's ability to coagulate (form clots) is impaired. [1] This condition can cause a tendency toward prolonged or excessive bleeding (bleeding diathesis), which may occur spontaneously or following an injury or medical and dental procedures.
