Quick and Easy Test for

Blood Rheology

Innovative Technology for Hemorheology

RheoSCAN-AnD300 can measure comprehensive rheological properties of blood within a short time (< 2 min). Now, RBC deformability, aggregation and aggregating force can be easily measured with a leading-edge microfluidic technology.

• Deformability : EI@3Pa, EImax, t1/2
• Aggregation : AI, M, ESR, t1/2
• Aggregating force : critical shear stress (CSS)
• Due to the quick and easy operation, RheoSCAN can be used at research laboratories and clinical environments.

Critical Shear Stress

Critical Shear Stress(CSS) is the minimum force required to disperse RBC aggregation.​ CSS is found to be independent of hematocrit.

The diagnosis takes less than 1 minute.

CSS only requires 500uL of whole blood sample.

RBC deformability requires 6uL of whole blood sample with PVP solution.

RBC aggregation is dispersed somewhere
