Coagulation measurement at the Point-of-Care

The coagulation measurement in the qLabs® Q3 ElectroMeter is based on the coagulometric method. A drop of blood is added to the thromboplastin reagent in the test strip and the time until fibrin formation is measured. With the blood sample thus clotting, the time of clotting is determined by the change in impedance.

The use of INR values (International Normalised Ratio) ensures direct comparability of measured values, worldwide. The "Quick value" (in %), which is still often used in Germany, depends on the test substance used by the respective laboratory. There are more than 25 different test substances from various manufacturers. The same blood can therefore have a "Quick value" of "10%" in one test procedure, which corresponds to a "Quick value" of "30%" in another test procedure.




INR-Values are independent:

  • The type of measurement (in the laboratory or in practice)
  • The measuring device used
  • The test substance used
  • Of the doctor performing the measurement (whether in the practice or during hospitalisation)

INR-Values are therefore comparable, Quick-values are NOT!

Experts recommend the use of the INR value as the unit for coagulation time determination

Your benefits at a glance

About 150,000 patients measure their INR value at home as part of their coagulation self-management. However, many of them have to go to the doctor regularly to have their coagulation value determined.

With qLabs® Q3 ElectroMeter PTZ-INR System kann der INR-Wert innerhalb ca. einer Minute patientennah bestimmt werden!
