The INRatio™ Meter: What it Does

Thrombotic Disorders
The human body has a complex mechanism that causes blood to clot if a wound occurs. Under normal circumstances this is a desirable response that enables wounds to heal, but under certain clinical conditions, called "thrombotic disorders", this same mechanism can cause an unwanted blood clot or "thrombus" that can be life threatening. Examples of thrombotic disorders include atrial fibrillation, heart attack, deep vein thrombosis, and acute ischemic stroke.

Oral Anticoagulants
Thrombotic disorders must be managed through the use of an oral anticoagulant, a drug which decreases the clotting ability of the blood so unwanted clots are prevented. More than 6 million people worldwide are treated with oral anticoagulants such as Coumadin® or generic sodium warfarin.

The Prothrombin Time Test
Oral anticoagulant treatments must be monitored carefully. If the dose is too low, an unwanted clot could form. If the dose is too high, there is risk of internal and external bleeding. A Prothrombin Time (PT) test is the most common way to measure the clotting tendency of blood, and is thus used to help manage oral anticoagulant therapy.

The INRatio Meter
The INRatio meter measures Prothrombin Time (PT), allowing oral anticoagulant patients to monitor the clotting time of their blood more effectively. The meter also reports results as an International Normalized Ratio (INR), a conversion unit which is a standardized method of reporting PT results.
