What Is an INR Report?
The INR (International Normalized Ratio) is a blood test that compares your blood’s clotting time to a standard. It’s used to manage conditions like blood thinners (anticoagulants) to prevent clots or bleeding. This report likely summarizes INR values measured during your hospitalization period, often linked to your treatment plan for conditions such as atrial fibrillation, deep vein thrombosis, or after certain surgeries.
Why Was This Test Done?
Your INR report was likely ordered to ensure your blood clotting is under control during your hospitalization. This may be part of a broader plan to prevent complications like excessive bleeding or blood clots, especially if you’re taking medications like warfarin or similar anticoagulants.
How Is the INR Report Used?
Doctors use this report to adjust your medication dose if needed, ensuring your blood clots appropriately without causing dangerous bleeding. It helps track trends over time, such as whether your INR stays within a safe range or if adjustments are required.
What Do the Results Mean?
The report may show a range of INR values measured at different times during your hospitalization. While specific values aren’t provided here, a typical INR between 2.0 and 3.0 is often used for certain anticoagulant therapies to balance clot prevention and bleeding risk. Your doctor will interpret these results in the context of your overall health and treatment plan.
Reference range
INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A
Inform your healthcare provider if you are taking blood thinners. No special preparation required.
