Home PT/INR Testing
PT/INR home testing is a convenient way for individuals on anticoagulant therapy to monitor their blood coagulation levels from the comfort of their own homes. This allows patients to quickly assess their INR levels, ensuring they stay within the target range prescribed by their healthcare provider, thereby enhancing self- management and reducing the need for frequent clinical visits.
The INR is calculated using this formula. This is a ratio of Prothrombin Times that providers or pharmacists use to make adjustments a patient’s warfarin dosage

Defining PT/INR
- PT Patient: Patient’s measured PT (seconds)
- PT Normal: Laboratory’s geometric mean value PT for normal patients not on warfarin (seconds)
- ISI: International Sensitivity Index (1.0)
- PT: Prothrombin Time (number of seconds it takes blood to clot)

What is the normal INR Range?
The normal INR range for most patients not on anticoagulant therapy is typically between 0.8 and 1.2. However, for individuals on anticoagulant medication such as warfarin, the target INR range may vary based on your condition being treated. Common target INR ranges for those on anticoagulants are generally between 2.0 and 3.0. It’s important to follow the specific target ranges set by your healthcare provider.
