whole blood reduced viscosity

Whole blood viscosity changes with the accumulation of red blood cells. The higher the hematocrit, the greater the viscosity of whole blood. In order to eliminate the influence of hematocrit and to compare the viscosity of different blood samples, some scholars introduced the concept of whole blood reduction viscosity. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Do not take anticoagulant drugs, such as aspirin, before testing. Normal value 6.65 to 8.15 mPa·s. Clinical significance (1) increased ischemic stroke, myocardial infarction, coronary atherosclerotic heart disease (coronary heart disease), pulmonary heart disease, thromboangiitis obliterans, arteriosclerotic embolism, tumor, multiple myeloma, original Macroglobulinemia, fibrinogen hyperplasia, polycythemia vera. (2) reduce hemorrhagic stroke, hematemesis and black feces (upper gastrointestinal bleeding), uterine bleeding, hemorrhagic shock. Low results may be diseases: dysfunctional uterine bleeding, high results may be diseases: polycythemia vera precautions It is forbidden to take anticoagulant drugs such as aspirin before testing. Inspection process (1) Turn on the instrument to warm up and let the constant temperature system reach the test temperature. (2) After the sample is kept at the test temperature for 5 minutes, mix well and add to the sample cup. (3) Press the measurement button and the shear rate is measured in descending order. In order to avoid the sinking of blood cells, the choice of shear rate should not be too much, and the retention time should not be too long. (4) After each sample is measured, the sample cup should be cleaned and dried. Not suitable for the crowd People who take aspirin for a long time. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
