Accurate results in less than a minute
The Coag-Sense meter directly measures the prothrombin time, so the time required to perform a test is the actual prothrombin time in seconds. By not using look-up tables or curve fitting algorithms, the Coag-Sense meter offers both speed and accuracy.

Superb Precision
Coag-Sense's patented micro mechanical detection system delivers superb precision and reliability. Professionals testing with the Coag-Sense system have demonstrated %CV's of 2.5%. Unlike electrochemical detection based devices, the Coag-Sense system does not rely on the concentration of blood constituents not involved in clot formation to produce results. This improves precision and reduces variability in readings often seen in other systems.

Red Blood Cells Not Required
Because the Coag-Sense system uses a micro mechanical means of clot detection instead of electrochemical, re-calcified plasma control strips can be run as easily as whole blood. This also means that the Coag-Sense system is not affected by low hemoglobin or hematocrit levels, a common source of inaccurate results in systems using current to detect clot formation.

Small sample size (10 µl minimum) for easy dosing
Only 10µl of fingerstick sample is required to run the Coag-Sense system. To reduce strip waste caused by unsteady hands, sample is easily transferred from the patient's finger to the test strip using the minipipette or sample transfer tubes provided.

Offers true controls using the actual thromboplastin and plasma
The purpose of quality control testing for a prothrombin time test system is to verify the integrity of both device and reagent performance. Coag-Sense is the first system to offer true high and low control strips which contain the same thromboplastin used in the patient test strip along with plasma of known INR. There is no substitute for confirming performance of the actual thromboplastin used in the patient test strips.

Other Benefits of the Coag-Sense System Include:
  • Portable, yet stable design
  • Barcoding on each test strip – no calibration code input or chip required
  • No test strip refrigeration required
  • No electrodes to clean or worry about
  • Enclosed detection wheel in each strip eliminates cross contamination risk
  • AC powered or battery powered for convenience
  • Testing, treatment and potential revenue capture in one appointment
  • Superior 24/7/365 Technical Support


When clinicians and researchers want the most accurate means of determining prothrombin time, they turn to either the World Health Organization (WHO) mechanical tilt-tube technique or the Fibrometer. Both these methods use a mechanical approach to directly detect clot formation, but they are cumbersome to perform. The new Coag-Sense PT/INR Monitoring System represents a breakthrough in point-of-care prothrombin time monitoring technology by miniaturizing and simplifying a direct mechanical means of detecting clot formation.

By directly detecting the clot, the Coag-Sense system avoids the challenges that plague other systems that use secondary means of clot detection like monitoring changes in impedance or pressure. For example, the concentration of red blood cells or other substances in blood sample can affect results in the measurement process of those products. The Coag-Sense system simply lifts the fibrin clot from the reaction well which interrupts a light beam. The PT time is the actual time from when the blood sample is applied to when the clot is formed. This produces results similar to the gold standard WHO tilt-tube methods as can be seen in the comparison graph below
