Alere INRatio PT / INR Monitor

The Alere INRatio PT/INR Monitoring System is a diagnostic point of care system that provides Prothrombin Time (PT) and International Normalized Ratio (INR) results using fresh capillary whole blood. The INRatio PT/INR Monitor reduces the headache of oral anticoagulation management, is easy to use, and features on board quality controls with every test. The Alere INRatio PT/INR Monitoring System provides results in less than two minutes using a simple finger stick procedure.

How it Works

  1. A Test Strip is inserted into the INRatio monitor.
  2. A drop of fresh whole blood from a fingerstick is applied to the test strip.
  3. The blood is drawn into the test area by capillary action where it mixes with reagents that cause coagulation to begin.
  4. The monitor performs the PT test AND 2 quality control tests (normal and therapeutic) simultaneously, and determines whether the controls are within preset limits. If they are, strip integrity is verified, and the monitor reports the PT test result. If they are not, the monitor displays an ERROR message.
  5. The test results are displayed in less than 60 seconds.

Prothrombin Time is a test of the blood's ability to clot. Blood clots form in response to vessel injury to prevent excessive loss of blood. If blood clots form inappropriately and lodge in the vascular system of important organs, serious consequences such as stroke can result. In certain medical conditions (i.e. atrial fibrillation or mechanical heart valves), blood clots are more likely to form and there is an increased risk of an adverse event.

Oral anticoagulants are used to prevent clots in these conditions. Oral anticoagulants have a narrow therapeutic range and the response to a standard dose varies widely both between patients and within a patient over time. Patients undergoing oral anticoagulant therapy must have their level of anticoagulation monitored often. Dosage adjustment should be made as needed to ensure maximum safety and efficacy.

INRatio empowers Healthcare Professionals to maintain complete control over PT/INR testing in support of improving patient care. INRatio provides results in less than two minutes using a simple fingerstick procedure. As studies have indicated, patients taking Warfarin that stay within their therapeutic range are significantly less likely to encounter an adverse event. INRatio enables facilities to meet the challenges of managing their oral anticoagulation patients.
