Blood viscosity is a direct measure of the ability of the blood to flow. It’s a basic biomarker for circulatory health.
Hemovister, Blood Analyzer is a computerized scanning capillary viscometer that measures both the thickness and stickiness of blood — the only blood viscometer able to provide a comprehensive viscosity profile from a blood sample in less than 4 minutes.
Viscosity is a basic, often overlooked biomarker for circulatory health. Blood viscosity is a direct measure of the ability of the blood to flow and is easily modifiable using existing therapies. Viscosity determines:

Hyperviscosity syndrome is a condition where blood is unable to flow freely through the circulatory system, thus decreasing the level of oxygen organs and tissues receive.
Hyperviscosity syndromes are a well-established class of conditions that can arise in a variety of disease states, including among others polycythemia vera, dysproteinemias, multiple myeloma, leukemia, sickle cell anemia, and sepsis.
Hyperviscosity includes syndromes of serum hyperviscosity where patients may hemorrhage or experience neurologic or ocular disorders; syndromes of polycythemic hyperviscosity that result in reduced blood flow or capillary perfusion and increased organ congestion; and, syndromes of hyperviscosity caused by reduced
deformability of red blood cells as in sickle cell anemia.

Hemovister Blood Analyzer is a computerized scanning capillary viscometer that delivers rapid and accurate measurements of both the thickness and stickiness of blood. It is FDA-cleared as a Class I viscometer and independently validated by the leading experts in the hemodynamics field.
Hemovister is the only blood viscometer able to provide a comprehensive viscosity profile from a blood sample in less than 4 minutes.
The Hemovister Blood Analyzer is a calibrated glass capillary system used to monitor changes in the amount of solids present in blood plasma in various disorders.
Test requirements: 4 mL of blood in lavender tube (EDTA), ambient stability 8 hours, refrigerated stability 4 days, frozen specimens unacceptable.
The Uvasic tube is used with the Hemovister Blood Analyzer for each blood viscosity test. Designed for testing biological fluids, the patented Uvasic tube is disposable and prevents the lab technician from making contact with the specimen.
The calibrated glass capillary is positioned horizontally between riser columns in a U-shape. Driven by gravity, the blood sample equilibrates from one column to the other by moving through the glass capillary, which is calibrated to ensure accuracy. The sweeping deceleration of blood flow as the column heights balance produces a complete viscosity scan.
