The qLabs® PTZ-INR test system consists of an ElectroMeter and PTZ-INR test strips. The qLabs® test system is designed to perform quantitative measurements of Prothrombin Time (PTZ) and International Normalized Ratio (INR) on fresh capillary whole blood. The qLabs® PTZ/ INR test strips are intended for in-vitro diagnosis in patients taking oral anticoagulants (blood thinners) who need to monitor the clotting time of their blood. They are suitable for both expert use and home use.
PTZ-INR tests measure the ability of blood to clot. Blood usually clots to reduce its flow when blood vessels are injured, thus preventing excessive bleeding. However, clotting that occurs inconveniently around the heart, lungs or brain can prevent normal blood flow and lead to life-threatening events such as a stroke or heart attack. Anticoagulant medication (blood thinners) is prescribed for patients who can no longer properly reabsorb blood clots and patients who have a low tolerance to clots. Because these medications have a narrow treatment window and can be sensitive to diets and lifestyles, it may be necessary to adjust a patient's dosage regularly. To provide the basis of a good decision regarding the need for such an adjustment, it is important for the patient to know the clotting status of their blood. The PTZ or INR value from the PTZ-INR test helps the patient or healthcare worker make these decisions. A fast and accurate measurement of the PTZ or INR value is crucial for the safety and effectiveness of anticoagulant therapy.
The clotting capacity of the blood is expressed as the Prothrombin Time (PTZ) or International Normalized Ratio (INR) value. While PT times may vary depending on the test method used, INR values should always be the same regardless of the method used. The International Normalized Ratio (INR) is recommended by the WHO to avoid reagent and test method dependency. The qlabs® ElectroMeter calculates the PTZ value based on an analysis of the test data and then converts it to the correct INR value.
