A blood rheology examination report
Hematocrit:
This refers to the ratio of blood cells to plasma in the blood, and it reflects the blood concentration. Increased hemocrit indicates thicker, more viscous blood, which is common in cerebral vascular diseases and polycythemia. Decreased hemocrit means thinner blood, with a corresponding decrease in blood viscosity, suggesting blood loss or anemia. Normal values: males 0.42-0.47, females 0.39-0.40.
Whole blood viscosity:
This reflects the blood’s viscosity, with higher viscosity leading to poorer fluidity. Increased whole blood viscosity suggests increased red blood cell aggregation, poor deformability or elasticity of red blood cells, and arterial wall hardening and roughness. Normal values: low shear, males 7.5-10.0, females 5.8-8.1; high shear, males 5.6-6.7, females 4.7-6.01.
Whole blood reduced viscosity:
This reflects the ability of blood cells to produce viscosity. Normal values: low shear, males 14-20, females 12-21; high shear, males 10-13, females 9-13.
Plasma viscosity:
This reflects the impact of large molecules (fibrinogen, globulin, triglycerides) in the blood on blood cell viscosity. Normal value: 1.64-1.78.
Erythrocyte electrophoresis time reflects the aggregation of blood cells. The shorter the time, the more positive charge there is on the surface of red blood cells, and the more dispersed they are, reducing aggregation. Prolongation of electrophoresis time is common in cerebral vascular disease, coronary heart disease, and arteriosclerosis. Normal: 13~17.4s.
Erythrocyte sedimentation rate is related to plasma density, viscosity, and aggregation force between red blood cells. In normal conditions, men: 0~21mm/h, women: 0~38mm/h.
Erythrocyte sedimentation rate equation K value, K value business reflects the enhancement of red blood cell aggregation.
Fibrinogen, during blood coagulation, fibrinogen polymerizes into fibrin polymers, with a “bridge” phenomenon occurring between them. It plays an important role in thrombosis formation in arteries and reflects the coagulability of blood. Normal: 2.4-3.7g/L.
Red blood cell deformability, a low value indicates the presence of hemolytic anemia, vascular diseases, diabetes, and liver disease.
Red blood cell rigidity index, the higher the rigidity index, the less the red blood cells deform, and it is one of the reasons for high blood viscosity. Normal for men: 7.16, women: 7.14.
Blood rheology examination, or blood viscosity testing, is an essential diagnostic tool in medicine that evaluates the flow properties of blood and its capacity to circulate efficiently within the vascular system. This examination is pivotal for several reasons. Firstly, it serves as an early indicator of cardiovascular diseases such as hypertension, coronary artery disease, and stroke. By detecting alterations in blood viscosity, healthcare providers can intervene early to prevent or manage these conditions effectively.
Moreover, abnormal blood viscosity can heighten the risk of blood clots, leading to serious health issues such as deep vein thrombosis (DVT) and pulmonary embolism. Regular blood rheology examinations are therefore crucial in monitoring this risk. Additionally, for patients with conditions that influence blood viscosity, such as diabetes or polycythemia, these tests help in assessing the efficacy of treatments, allowing for timely adjustments in medication or lifestyle changes.
Blood rheology tests also contribute to the evaluation of anemia and other blood disorders, guiding further diagnostic steps and treatment plans. Furthermore, the data from these tests is invaluable for medical research, aiding in the development of new treatments and understanding the underlying mechanisms of various diseases. As the field of medicine leans more towards personalized care, the insights from blood rheology examinations are increasingly important for tailoring treatments to individual needs, potentially enhancing outcomes and minimizing side effects.
In essence, the blood rheology examination report is a critical component in the healthcare provider’s toolkit for assessing, monitoring, and managing a spectrum of health conditions. It not only aids in early diagnosis but also plays a significant role in treatment planning and overall patient care.
