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


The new Coag-Sense system offers healthcare professionals an easy and efficient way to obtain accurate and reliable PT/INR results at the point of care. Now you can make immediate therapy adjustments and improve patient satisfaction. To learn more, please contact Customer Service at 866-903-0890.
