2023年3月16日 · An international normalized ratio (INR) is a blood test that indicates how well the blood is able to clot. People who take warfarin (Coumadin) need to monitor this level to make sure it doesn’t go too high or too low. A normal INR range is …

A prothrombin time (PT/INR) test measures how fast a blood sample forms a clot. Healthcare providers often do this test to monitor how fast your blood clots if you’re taking the blood thinner warfarin. It’s also used to diagnose blood disorders. A high PT/INR means your body takes longer than normal to form blood clots.

国际标准化比值（international normalized ratio，INR）是患者凝血酶原时间与正常对照凝血酶原时间之比的ISI次方（ISI：国际敏感度指数，试剂出厂时由厂家标定），是可以校正凝血活酶试剂差异对凝血酶原时间测值进行标准化报告的方法。

2019年8月15日 · International normalized ratio (INR) is blood-clotting test. It is a test used to measure how quickly your blood forms a clot, compared with normal clotting time. A normal INR is 1.0. Each increase of 0.1 means the blood is slightly thinner (it takes longer to clot). INR is related to the prothrombin time (PT).

A prothrombin time test with an INR (PT/INR) measures how long it takes blood to clot. It's used to diagnose and manage bleeding and clotting disorders.

2023年12月5日 · INR为国际标准化比值的缩写，INR的正常值是0.8-1.5，INR的值越高，血液凝固所需的时间越长。 但是，如果INR值非常高时，就会出现无法控制的出血的风险。 INR可有效监测使用抗凝药物的效果，通常使用抗凝药物华法林，需要监测INR。 一旦使用华法林，就应规律性的监测INR，有静脉血栓的患者需要口服华法林，INR值一般应保持在2.0-2.5。 有心房颤动的患者，口服华法林的INR值一般应保持在2.0-3.0。 INR值高于4.0时，可能会引起无法控制的出 …

2024年12月3日 · 健康成年人，inr 值大约 1.0；inr 的值越高，血液凝固所需的时间越长。 因此，如果 INR 太低，表明可能有形成血栓的危险；INR 过高，则可能表示出血 ...

凝血酉每原時間(Prothrombin Time，PT)是廣泛被使用的常規檢驗項目，主要用於追蹤口 服抗凝劑Warfarin (Coumarin)藥物治療，外在和共同路徑之血液凝固因子(Coagulation fa- ctor)減少或缺乏之篩檢，PT之檢驗報告方式從早期用”秒”，到目前普遍使用INR(Inte- rnational Normalize ...

The international normalized ratio (INR) is a standardized number that's figured out in the lab. If you take blood thinners, also called anticlotting medicines or anticoagulants, it may be important to check your INR. The INR is found using the results of the prothrombin time (PT) test. This measures the time it takes for your blood to clot.

The international normalised ratio (INR) blood test tells you how long it takes for your blood to clot. A test called the prothrombin time (PT) actually measures how quickly your blood clots. The PT results can be expressed as an INR to standardise the results.
