Plasma Viscosity (PV)

Plasma viscosity is about 1/8 to 1/4 of the viscosity of whole blood, which is one of the indicators reflecting blood fluidity. Generally, plasma viscosity is mainly related to changes in the molecular compound, such as fibrinogen, globulin, blood lipids and sugars. Increased plasma viscosity leads to poor blood flow and even blockage, which can reflect the presence of congestion. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Reduced in low proteinemia. Normal value: Male: 0.85-1.99 mPa / sec Female: 0.82-1.84 mPa / sec Above normal: Increased in macroglobulinemia. negative: Positive: Tips: Do not take anticoagulant drugs, such as aspirin, before testing. Normal value Male 0.85 to 1.99 mPa / s. Female 0.82 to 1.84 mPas/sec. Clinical significance Increased plasma viscosity is seen in macroglobulinemia, multiple myeloma, globulinemia, hypertension, hyperlipidemia, and the like. The decrease in plasma viscosity is seen in hypoproteinemia, various anemias, liver diseases, and the like. Low results may be diseases: anemia considerations 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.
