8 Ιουν 2024 · International Normalized Ratio. INR is a standardized measure of PT, ensuring consistency in results across different laboratories. The normal range for INR is around 0.8 to 1.2. Higher INR values suggest a slower clotting time and an increased risk of bleeding.
1 Μαΐ 2023 · Introduction. International normalized ratio (INR) is the preferred test of choice for patients taking vitamin K antagonists (VKA). It can also be used to assess the risk of bleeding or the coagulation status of the patients. Patients taking oral anticoagulants are required to monitor INR to adjust the VKA doses because these vary between patients.
For patients treated with VKAs, we recommend a therapeutic INR range of 2.0 to 3.0 (target INR of 2.5) rather than a lower (INR < 2) or higher (INR 3.0-5.0) range (Grade 1B). 4.2 Therapeutic Range for High-Risk Groups
3 Μαρ 2009 · The INR ensures that PT results obtained by different laboratories can be compared. It is important to monitor the INR (at least once a month and sometimes as often as twice weekly) to make sure that the level of warfarin remains in the effective range.
The recommended therapeutic range for the INR (which is calculated from the patient's PT, a mean control PT, and the international sensitivity index) for oral anticoagulant treatment of most conditions is 2.0 to 3.0. In patients with mechanical cardiac valves, the INR should be at least 2.5 to 3.5.
1 Οκτ 2019 · Vitamin K antagonists (e.g., warfarin [Coumadin]), unfractionated heparin, low-molecular-weight heparin (LMWH), and direct oral anticoagulants are commonly used for the prevention and treatment...
