Simply so, what causes high PT?
Causes of prolonged PT include the following: Warfarin use. Vitamin K deficiency from malnutrition, biliary obstruction, malabsorption syndromes, or use of antibiotics. Liver disease, due to diminished synthesis of clotting factors.
One may also ask, what is the difference between PT and INR? PT and INR are both measures of how long it takes your blood to clot, expressed in two different ways. PT stands for prothrombin time. It is a measure in seconds of how long it takes your blood to clot. The INR is a formula that allows for differences between laboratories so that test results can be compared.
Correspondingly, what is a normal PT level?
PT is measured in seconds. Most of the time, results are given as what is called INR (international normalized ratio). If you are not taking blood thinning medicines, such as warfarin, the normal range for your PT results is: 11 to 13.5 seconds. INR of 0.8 to 1.1.
What is a good PT INR level?
In healthy people an INR of 1.1 or below is considered normal. An INR range of 2.0 to 3.0 is generally an effective therapeutic range for people taking warfarin for disorders such as atrial fibrillation or a blood clot in the leg or lung.
