'''INR''' (International Normalized Ratio) measures how long your blood takes to clot. If you take a blood thinner like warfarin, your clinician sets a target INR band and you test regularly to stay inside it. Loopa lets you log INR inside [[Vitals tracking]] and flags each reading against your own target band.
This is opt-in and informational only. It is not medical advice and Loopa never advises on dosing. Never change your medication based on a reading here. Follow your clinician and your anticoagulation clinic.
== Turn it on and set your band ==
INR is off by default. Turn on the INR tracker in Settings, then set your '''target band''' (for example 2.0 to 3.0). Your clinician gives you this range. Once set, it appears as a hint on the log form and under the INR column in your history.
== Log a reading ==
On the '''Vitals''' page, enter INR as a ratio to one decimal, like 2.5. Valid entries run from 0.5 to 10.0. Save. INR only appears when the tracker is on.
== What the reading means ==
INR is a unitless ratio. Higher means your blood clots more slowly. Loopa grades each reading against the band you set:
- '''In range''': inside your target band.
- '''Below target''': under the low end. Clotting risk skews higher.
- '''Above target''': over the high end. Bleeding risk skews higher.
Common target bands run from 2.0 to 3.0 for many conditions, and higher (often 2.5 to 3.5) for some mechanical heart valves.<ref>{{cite web|title=A Patient's Guide to Taking Warfarin|url=https://www.heart.org/en/health-topics/arrhythmia/prevention--treatment-of-arrhythmia/a-patients-guide-to-taking-warfarin|website=American Heart Association|access-date=June 30, 2026}}</ref> Your band is personal. Use the one your clinician gave you.
== Track the trend ==
When INR is on, the '''Trends''' card charts your last 30 days and the '''History''' table shows each reading with its in, below, or above chip and your band. Bring this trend to your INR checks. Many things move INR, including diet (especially vitamin K), alcohol, illness, and other medications.
