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.

hematology analyzer RheoSCAN Q1

Impaired RBC Deformability leads to hypoxia

RBC deformability plays a critical role in blood circulation. Healthy RBCs have to pass through capillaries whose diameter is smaller than their size. Decreased red blood cell deformability results in hypoxia due to decreased oxygen delivery capacity in blood vessels.

→ Serious problem in micro-circulation

hematology analyzer RheoSCAN Q2

Hyper-aggregated RBCs result in vascular diseases


RBC aggregation is one of the key factors in determining blood flow resistance in microcirculation. Healthy red blood cells are easy to disaggregate and enter small vessels in an efficient manner, whereas hyper-aggregated red blood cells do not dis-aggregate and causes local hypertension, vascular sclerosis, and hypoxia.

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.
