Blood viscosity measurement

With the continuous improvement of social life, people pay more and more attention to their physical health, so physical examination has become an indispensable part of many people's daily life. Blood viscosity measurement can be used to understand the fluidity and various changing patterns of people's blood. It can help medical staff better understand people's physical conditions. Friends in need can learn more about the relevant knowledge.

Determination of whole blood and plasma viscosity is of great significance for understanding blood fluidity and its changing patterns under physiological and pathological conditions, evaluating the causes of microcirculatory disorders, and diagnosing, preventing and treating diseases with abnormal blood viscosity.

Clinical data show that many diseases that manifest obvious microcirculatory disorders are accompanied by increased whole blood and plasma viscosity. Moreover, the degree of microcirculation disturbance and the severity of the disease are parallel to the increase in whole blood and plasma viscosity. Microcirculation disorders accompanied by increased whole blood or plasma viscosity are common in many diseases, such as cerebral stroke, myocardial infarction, coronary heart disease, cor pulmonale, etc. If treated, blood viscosity will decrease as clinical symptoms and microcirculation disorders improve.

The determination of blood viscosity is of great significance in the differential diagnosis of ischemic and hemorrhagic stroke, observation of therapeutic efficacy, and post-treatment judgment. In recent years, the relationship between changes in blood rheology and cerebrovascular disease has attracted increasing attention. The factors that affect blood rheology mainly include hematocrit, whole blood viscosity, plasma viscosity, red blood cell electrophoresis time, erythrocyte sedimentation rate and fibrinogen. Changes in these indicators directly affect the fluidity, viscosity and coagulation of blood. If the changes exceed the normal range, they may cause cerebrovascular disease. In hemorrhagic stroke, the most obvious decrease is in whole blood viscosity and hematocrit (plasma viscosity and fibrinogen content are both reduced, and red blood cell electrophoresis time is shortened). It indicates the occurrence of hemorrhagic vascular disease. In ischemic stroke, whole blood viscosity, plasma viscosity and other blood rheology test indicators all increase. Among them, increased cell volume and whole blood viscosity are the main causes of ischemic vascular disease.
