About PT/INR Testing
A PT test measures the time it takes for blood to form a clot. Most labs will report PT test results using INR which is a calculated measurement that adjusts for laboratory test variances. A PT test is regularly scheduled to monitor prothrombin levels for patients taking Warfarin, a blood thinner. Warfarin aids in the prevention of blood clots and conditions that may result like deep vein thrombosis or pulmonary embolism.
The PT2 Monitoring System
The Coag-Sense® PT2 System offers superior accuracy and precision in a portable format. Measurement of the patient sample uses our patented direct clot technology and measures actual clot time. No algorithms or look-up tables are required. Only a 10-12 µl sample is needed. The sample is applied to the test strip using a transfer tube to place the required amount in the appropriate place. Results are available in less than one minute and can be communicated to providers via USB, Wi-Fi, or Bluetooth. Explore a variety of resources including videos, user manuals, and FAQs.
