Our platform is built around acoustic levitation technology that enables quantitative viscoelastic and optical measurements of a sample with high accuracy and repeatability. This non-contact technique avoids premature clotting due to surface contamination for higher reliability.
Coagulation measurements are performed without any surfaces contacting the sample, avoiding contamination and tainted results.
Small sample volume
Only one drop of blood (< 6 µL) is needed for testing. 60x less than competing solutions.
Plasma and blood assays with the ability to monitor viscoelasticity, PT, aPTT, thrombin generation and platelet function simultaneously.
Tests are completed within 10 minutes.
